Generally, if vi is displaying printable characters ++ in octal/hexadecimal forms, your environment is not configured correctly. ++ Try looking at the man pages that allow you to configure your locale. ++ For example, to configure an ISO 8859-1 locale under Solaris using csh, ++ you would do: ++ ++ setenv LANG C ++ setenv LC_CTYPE iso_8859_1 ++ ++ Other LC_CTYPE systems/values that I'm told work: ++ ++ System Value ++ ====== ===== ++ FreeBSD lt_LN.ISO_8859-1 ++ HP-UX 9.X american.iso88591 ++ HP-UX 10.X en_US.iso88591 ++ SunOS 4.X iso_8859_1 ++ SunOS 5.X iso_8859_1 ++ ++ If there's no other solution, you can use the print and noprint edit ++ options of vi to specify that a specific character is printable or not ++ printable. ++ ++Q: My map won't work! ++A: One thing that you should immediately check if a vi map doesn't work ++ is if depends on the final cursor position after a P or p command. ++ Historic vi's were inconsistent as to the final position of the cursor, ++ and, to make matter worse, the final cursor position also depended on ++ whether the put text came from a named or unnamed buffer! Vi follows ++ the POSIX 1003.2 standard on this one, and makes this consistent, always ++ placing the cursor on the first character. ++ ++Q: I'm using ksh or csh as my vi edit option shell value, and file ++ expansions don't work right! ++A: The problem may be in your ksh or csh startup files, e.g., .cshrc. Vi ++ executes the shell to do name expansion, and the shell generally reads ++ its startup files. If the startup files are not correctly configured ++ for non-interactive use, e.g., they always echo a prompt to the screen, ++ vi will be unable to parse the output and things will not work ++ correctly. ++ ++Q: How does the iclower edit option differ from the ignorecase (i.e. ic) ++ edit option? ++A: The difference is that the ignorecase edit option always ignores the ++ case of letters in the Regular Expression (RE), and the iclower edit ++ option only ignores the case if there are no upper-case letters in the ++ RE. If any upper-case letters appear in the Regular Expression, then ++ it will be treated case-sensitively, as if the ignorecase edit option ++ was not set. ++ ++Q: When I edit binary files, vi appends a <newline> to the last line! ++A: This is historic practice for vi, and further, it's required by the ++ POSIX 1003.2 standard. My intent is to provide a command line and/or ++ edit option to turn this behavior off when I switch to version 2.0 of ++ the Berkeley DB package. ++ ++Q: My cursor keys don't work when I'm in text input mode! ++A: A common problem over slow links is that the set of characters sent by ++ the cursor keys don't arrive close enough together for vi to understand ++ that they are a single keystroke, and not separate keystrokes. Try ++ increasing the value of the escapetime edit option, which will cause ++ vi to wait longer before deciding that the <escape> character that ++ starts cursor key sequences doesn't have any characters following it. ++ ++Q: When I edit some files, vi seems to hang forever, and I have to kill it. ++A: Vi uses flock(2) and fcntl(2) to do file locking. When it attempts to ++ acquired a lock for a file on an NFS mounted filesystem, it can hang ++ for a very long (perhaps infinite) period of time. Turning off the ++ "lock" edit option will keep vi from attempting to acquire any locks ++ on the files you edit. ++ ++Q: When I compile vi I get lots of warnings about pointer assignments ++ being incompatible! ++A: Vi is partially written to support wide characters. When this code ++ interfaces with the code that doesn't yet support wide characters, ++ the pointer types clash. This will hopefully be fixed in the near ++ future, but I've been saying that for awhile, now. ++ ++Q: I get jumpy scrolling behavior in the screen! ++A: This is almost certainly a problem with the system's terminfo or ++ termcap information for your terminal. If the terminfo/termcap entry ++ doesn't have the settable scrolling region capabilities, or the more ++ powerful scrolling commands, these behaviors can result. Historic ++ implementations of vi, and some of the vi clones, don't suffer from ++ this problem because they wrote their own screen support instead of ++ using the curses library. ++ ++ The solution is to find a good terminfo or termcap entry for your ++ terminal, which will fix the problem for all of the applications on ++ your system, not just vi. Eric Raymond maintains the freely ++ redistributable termcap/terminfo entries. They can be downloaded ++ from http://www.ccil.org/~esr/ncurses.html, or you can contact him ++ at esr@snark.thyrsus.com. ++ ++Q: The entire screen repaints on every keystroke! ++A: Your system's curses implementation is broken. You should use the ++ curses implementation provided with vi or a curses replacement such ++ as ncurses. Eric Raymond is one of the maintainers of the freely ++ redistributable ncurses package. You can download ncurses from ++ http://www.ccil.org/~esr/ncurses.html, or you can contact him at ++ esr@snark.thyrsus.com. ++ ++Q: When I use vi on a Sun console (terminal type sun-34) the screen ++ is occasionally trashed, usually when exiting vi! ++A: The Sun console can't handle the 'al' capability of the termcap ++ entry (the il1 capability of terminfo entries). If you delete that ++ entry from your terminfo/termcap information everything should work ++ correctly. ++ ++Q: I don't have a version of ctags (or I have ctags, but it doesn't tag ++ nearly enough things)! ++A: There's a version of ctags available on the 4.4BSD-Lite distributions, ++ as well as the FreeBSD, NetBSD, Linux and GNU distributions. Or, you ++ might want to try Exuberant Ctags: ++ ++ Title: Exuberant Ctags ++ Version: 1.3 ++ Entered-date: 16JUN96 ++ Description: ++ A better ctags which generates tags for all possible tag types: ++ macro definitions, enumerated values (values inside enum{...}), ++ function and method definitions, enum/struct/union tags, external ++ function prototypes (optional), typedefs, and variable ++ declarations. It is far less easily fooled by code containing #if ++ preprocessor conditional constructs, using a conditional path ++ selection algorithm to resolve complicated choices, and a ++ fall-back algorithm when this one fails.

It's no ++ longer possible to use the # command itself to repeat or modify ++ a previous # command, '.' is the only possibility. ++ + Lots more reworking of the ex addresses, putting ? and / into ++ the ex addressing code broke the world. ++ + Make the Put, Preserve and Print commands work (don't ask). ++ + Split stdout/stderr from shell expansions; stdout is expansion ++ text, stderr is entered on the message queue. ++1.40 -> 1.41 Fri Nov 18 16:13:52 1994 ++ + Addition of a port for AUX 3.1 ++ + Addition of a message catalog for Russian. ++ + Make vi ? and / commands be true ex addresses (historic practice). ++ + Display the date first in vi -r recovery list. ++1.39 -> 1.40 Mon Nov 14 10:46:56 1994 ++ + Two bug fixes for 1.39; -r option and v_change core dump. ++1.38 -> 1.39 Sun Nov 13 18:04:08 1994 ++ + Ex substitution with confirmation now matches historic practice ++ (except that it still runs in raw mode, not cooked). ++ + Nvi now clears the screen before painting, if repainting the ++ entire screen. ++ + Fix final cursor position for put command entering text in a ++ single line. ++ + Change to break error message lines on the last <blank> in the ++ line. ++ + Always center the current line when returning to a previously ++ edited file or moving to a tag line that's not visible on the ++ screen. ++ + Change write of the current file using an explicit name or % to ++ match the semantics of :w<CR>, not :w file<CR>. ++ + Add command aliases to vi, and remap 6 historic commands to their ++ historic counterparts: D->d$, Y->y_, S->c_, C->c$, A->$a, I->^i. ++ + Match option display to historic practice; if boolean or numeric ++ options changed to default values, not displayed by default. ++ Nvi treats string options the same way, vi always displayed any ++ string option that was changed. ++ + Added lock edit option, if not set, no file locking is done. ++ + Rework ex to permit any ex command in the EXINIT variable or ++ exrc startup files. This fixes the bug were `vi +100 file' ++ painted the screen and then moved to line 100 and repainted. ++ (Yanked to SCCS ID 9.1.) ++ + Bug fix: could report file modified more recently than it was ++ written, incorrectly. ++ + Search fix: historically, motions with deltas were not corrected ++ to the previous/next line based on the starting/stopping column. ++ + Addressing fixes: make trailing non-existent addresses work, change ++ % to be text substitution, not a unique address (to follow future ++ POSIX). ++1.37 -> 1.38 Mon Oct 24 12:51:58 1994 ++ + Scrolling fix; ^B can move to nonexistent lines. ++ + Fix to vi mapped commands; <escape> characters while already in ++ command mode did not historically cause the mapped characters to ++ be flushed. ++ + Add the backup edit option, automatically version edit files. ++ + Make it possible to edit files that db can't read, i.e. edit a ++ temporary file, with the correct file name. ++ + Only anchor the last line of the file to the bottom line of the ++ screen if there's half or less of a screen between the target ++ line and the end of the file. ++ + Fix wrapmargin text allocation bug. ++ + Fix ex put command to work in any empty file. ++ + Fix global command to handle move's to line 0 correctly. ++ + Regularize the yank cursor motions, several bug fixes for historic ++ practice. ++ + Fix N and n, when used as a motion command for the ! command, ++ repeat the last bang command instead of prompting for a new ++ one. ++ + Timeout maps beginning with <escape> quickly, instead of based ++ on the keytime option. ++ + Bug fix for wraplen option, wasn't triggered for input commands. ++1.36 -> 1.37 Sun Oct 9 19:02:53 1994 ++ + Change PORT directories to install patches before distribution. ++ + Fix ^A to set search direction and pattern for consistency. ++ + Fold the showdirty option into the showmode option. ++ + Ex addressing fix: change search offset and line arguments (e.g. ++ the copy command) to be ex addressing offsets, matching historic ++ practice. ++ + Ex addressing fix: support ^ as an offset/flag equivalent to -. ++ + Ex addressing fix: historically, any missing address defaulted to ++ dot, e.g. "4,,," was the same as ".,.". ++ + Ex addressing fix: historically, <blank> separated numbers were ++ additive, e.g. "3 5p" displayed line 8. ++ + Ex addressing fix: make ';' as a range delimiter match historic ++ practice. ++ + Change nvi to exit immediately if stdout isn't a terminal. ++ + Change alternate file name behavior to match historic practice, ++ make the :write command set the current file name. ++ + Text input fix; input keys from a map, with an associated count, ++ weren't historically affected by the wrapmargin value. ++ + Add wraplen option, same as wrapmargin, but from the left-hand ++ column, not the right. ++ + Make ex address .<number> be equivalent to .+<number>, i.e. the ++ '+' is understood; matches historic practice, and it's widely ++ documented for ed(1). ++ + Input mode ^V^J historically mapped into a single ^J. ++ + Minor catalog changes, fixes; don't use 's' to pluralize words. ++1.35 -> 1.36 Thu Sep 8 08:40:25 1994 ++ + Don't overwrite user's maps with standard (termcap) mappings. ++ + Make \ escape kill and erase characters in vi text input mode. ++ + Fix ^D autoindent bug by resolving leading <blank>s at ^D. ++ + Rework abbreviation tests (again!) to match historic practice. ++ + Change ^D/^U default scrolling value to be based on window option ++ value, not screen lines, correct scrolling option value, both to ++ match historic practice.

In addition, it sets the last '!' command. ++1.27 -> 1.28 Wed Jul 27 21:29:18 1994 ++ + Add support for scrolling using the CS and SF/sf/SR/sr termcap ++ strings to the 4BSD curses. ++ + Rework of getkey() introduced a bug where command interrupt put ++ nvi into an infinite loop. ++ + Piping through a filter historically cut the replaced lines into ++ the default buffer, although not the numeric ones. ++ + Read of a filter and !! historically moved to the first nonblank ++ of the resulting cursor line (most of the time). ++ + Rework cursor motion flags, to support '!' as a motion command. ++1.26 -> 1.27 Tue Jul 26 10:27:58 1994 ++ + Add the meta option, to specify characters the shell will expand. ++ + Fix the read command to match historic practice, the white space ++ and bang characters weren't getting parsed correctly. ++ + Change SIGALRM handler to save and restore errno. ++ + Change SunOS include/compat.h to include <vfork.h> so that the ++ ex/filter.c code works again. ++ + Don't put lines deleted by the ex delete command into the numeric ++ buffers, matching historic practice. ++ + Fix; if appending to a buffer, default buffer historically only ++ references the appended text, not the resulting text. ++ + Support multiple, semi-colon separated search strings, and 'z' ++ commands after search strings. ++ + Make previous context mark setting match historic practice (see ++ docs/internals/context). ++ + Fix the set command to permit whitespace between the option and ++ the question mark, fix question marks in general. ++ + Fix bug where ex error messages could be accidentally preceded ++ by a single space. ++ + Fix bug where curses reorganization could lose screen specific ++ mappings as soon as any screen exited. ++ + Fix bug in paragraph code where invalid macros could be matched. ++ Make paragraph motions stop at formfeed (^L) characters. ++ + Change 'c' to match historic practice, it cut text into numeric ++ buffers. ++1.25 -> 1.26 Tue Jul 19 17:46:24 1994 ++ + Ignore SIGWINCH if the screen size is unchanged; SunOS systems ++ deliver one when a screen is uncovered. ++ + Fix: don't permit a command with a motion component to wrap due ++ to wrapscan and return to the original cursor position. ++ + Fix: ^E wasn't beeping when reaching the bottom of the file. ++ + Fix bg/fg bug where tmp file exiting caused a NULL dereference. ++ + Rework file locking code to use fcntl(2) explicitly. ++ + Fix bug in section code where invalid macros could be matched. ++ + Fix bug where line number reset by vi's Q command. ++ + Add explicit character mode designation to character mode buffers. ++ + Add <sys/ioctl.h> include to sex/sex_window.c, needed by NET/2 ++ vintage systems. ++ + Change to always flush a character during suspend, 4BSD curses ++ has the optimization where it doesn't flush after a standend(). ++ + Fix bug on OSF1 where <curses.h> changes the values of VERASE, ++ VKILL and VWERASE to incorrect ones. ++ + Fix bug where optarg used incorrectly in main.c. ++ + Block all signals when acting on a signal delivery. ++ + Fix recovery bug where RCV_EMAIL could fire even if there wasn't ++ a backing file; format recovery message. ++1.24 -> 1.25 Sun Jul 17 14:33:38 1994 ++ + Stop allowing keyboard suspends (^Z) in insert mode, it's hard ++ to get autowrite correct, and it's not historic practice. ++ + Fix z^, z+ to match historic practice. ++ + Bug in message handling, "vi +35 non-existent_file" lost the ++ status message because the "+35" pushed onto the stack erased ++ it. For now, change so that messages aren't displayed if there ++ are keys waiting -- may need to add a "don't-erase" bit to the ++ character in the stack instead. ++ + Bug in svi_msgflush(), where error messages could come out in ++ normal video. ++1.23 -> 1.24 Sat Jul 16 18:30:18 1994 ++ + Fix core dump in exf.c, where editing a non-existent file and ++ exiting could cause already free'd memory to be free'd. ++ + Clean up numerous memory errors, courtesy of Purify. ++ + Change process wait code to fail if wait fails, and not attempt ++ to interpret the wait return information. ++ + Open recovery and DB files for writing as well as reading, System ++ V (fcntl) won't let you acquire LOCK_EX locks otherwise. ++ + Fix substitute bug where could malloc 0 bytes (AIX breaks). ++ + Permit the mapping of <carriage-return>, it's historic practice. ++ + Historic vi didn't eat <blank> characters before the force ++ flag, match historic practice. ++ + Bug in ex argument parsing, corrected for literal characters ++ twice. ++ + Delete screen specific maps when the screen closes. ++ + Move to the first non-<blank> in the line on startup; historic ++ practice. ++ + Change the ex visual command to move directly to a line if no ++ trailing 'z' command. ++ + Fix "[[" and "]]" to match historic practice (yet again...). ++ + Fix "yb" and "y{" commands to update the cursor correctly. ++ + Change "~<motion>" to match the yank cursor movement semantics ++ exactly. ++ + Move all of the curses related code into sex/svi -- major rework, ++ but should help in future ports. ++ + Fix bug in split code caused by new file naming code, where would ++ drop core when a split screen exited. ++ + Change svi_ex_write to do character display translation, so that ++ messages with file names in them are displayed correctly. ++ + Display the file name on split screens instead of a divider line. ++ + Fix move bug, wasn't copying lines before putting them. ++ + Fix bug were :n dropped core if no arguments supplied. ++ + Don't quote characters in executed buffer: "ifoo<esc>" should leave ++ insert mode after the buffer is executed. ++ + Tagpop and tagpush should set the absolute mark in case only moving ++ within a file. ++ + Skip leading whitespace characters before tags and cursor word ++ searches. ++ + Fix bug in ex_global where re_conv() was allocating the temporary ++ buffer and not freeing it. ++1.22 -> 1.23: Wed Jun 29 19:22:33 1994 ++ + New <sys/cdefs.h> required "inline" to change to "__inline" ++ + Fix System V curses code for new ^Z support. ++ + Fix off-by-one in the move code, avoid ":1,$mo$" with only one ++ line in the buffer. ++ + Line orientation of motion commands was remembered too long, ++ i.e. '.' command could be incorrectly marked as line oriented. ++ + Move file modification time into EXF, so it's shared across ++ split screens. ++ + Put the prev[ious] command back in, people complained. ++ + Random fixes to next/prev semantics changed in 1.22. ++ + Historically vi doesn't only move to the last address if there's ++ ANYTHING after the addresses, e.g. ":3" moves to line 3, ":3|" ++ prints line 3. ++1.21 -> 1.22: Mon Jun 27 11:01:41 1994 ++ + Make the line between split screens inverse video again. ++ + Delete the prev[ious] command, it's not useful enough to keep. ++ + Rework :args/file name handling from scratch -- MAJOR CHANGE, ++ likely to introduce all sorts of new bugs. ++ + Fix RE bug where no subexpressions in the pattern but there were ++ subexpressions referenced in the replacement, e.g. "s/XXX/\1/g". ++ + Change recovery to not leave unmodified files around after a ++ crash, by using the owner 'x' bit on unmodified backup files. ++ MAJOR CHANGE, the system recovery script has to change! ++ + Change -r option to delete recovery.* files that reference non- ++ existent vi.* files. ++ + Rework recovery locking so that fcntl(2) locking will work. ++ + Fix append (upper-case) buffers, broken by cut fixes. ++ + Fix | to not set the absolute motion mark. ++ + Read $HOME/.exrc file on startup if the effective user ID is ++ root. This makes running vi while su(1)'d work correctly. ++ + Use the full pathname of the file as the recovery name, not ++ just the last component. Matches historic practice. ++ + Keep marks in empty files from being destroyed. ++ + Block all caught signals before calling the DB routines. ++ + Make the line change report match historic practice (yanked ++ lines were different than everything else). ++ + Add section on multiple screens to the reference manual. ++ + Display all messages at once, combine onto a single line if ++ possible. Delete the trailing period from all messages. ++1.20 -> 1.21: Thu May 19 12:21:58 1994 ++ + Delete the -l flag from the recover mail. ++ + Send the user email if ex command :preserve executed, this matches ++ historic practice. Lots of changes to the preserve and recovery ++ code, change preserve to snapshot files (again, historic practice). ++ + Make buffers match historic practice: "add logically stores text ++ into buffer a, buffer 1, and the unnamed buffer. ++ + Print <tab> characters as ^I on the colon command line if the ++ list option set. ++ + Adjust ^F and ^B scroll values in the presence of split screens ++ and small windows. ++ + Break msg* routines out from util.c into msg.c, start thinking ++ about message catalogs. ++ + Add tildeop set option, based on stevie's option of the same name. ++ Changes the ~ command into "[count] ~ motion", i.e. ~ takes a ++ trailing motion. ++ + Chose NOT to match historic practice on cursor positioning after ++ consecutive undo commands on a single line; see vi/v_undo.c for ++ the comment. ++ + Add a one line cache so that multiple changes to the same line ++ are only counted once (e.g. "dl35p" changes one line, not 35). ++ + Rework signals some more. Block file sync signals in vi routines ++ that interface to DB, so can sync the files at interrupt time. ++ Write up all of the signal handling arguments, see signal.c. ++1.19 -> 1.20: Thu May 5 19:24:57 1994 ++ + Return ^Z to synchronous handling.

This is historic practice. ++ + Change "lock failed" error message to a file status message. ++ It always fails over NFS, and making all NFS files readonly ++ isn't going to fly. ++ + Use the historic line number format, but check for overflow. ++ + Fix bug where vi command parser ignored buffers specified as ++ part of the motion command. ++ + Make [@*]buffer commands on character mode buffers match historic ++ practice. ++ + Fix bug where the cmap/chf entries of the tty structure weren't ++ being cleared when new characters were read. ++ + Fix bug where the default command motion flags were being set ++ when the command was a motion component. ++ + Fix wrapmargin bug; if appending characters, and wrapmargin breaks ++ the line, an additional space is eaten. ++1.14 -> 1.15: Fri Apr 29 07:44:57 1994 ++ + Make the ex delete command work in any empty file. ++ + Fix bug where 't' command placed the cursor on the character ++ instead of to its left. ++ + ^D and ^U didn't set the scroll option value historically. ++ Note, this change means that any user set value (e.g. 15^D) ++ will be lost when splitting the screen, since the split code ++ now resets the scroll value regardless. ++ + Fix the ( command to set the absolute movement mark. ++ + Only use TIOCGWINSZ for window information if SIGWINCH signal ++ caught. ++ + Delete the -l flag, and make -r work for multiple arguments. ++ Add the ex "recover[!] file" command. ++ + Switch into ex terminal mode and use the sex routines when ++ append/change/insert called from vi mode. ++ + Make ^F and ^B match historic practice. This required a fairly ++ extensive rework of the svi scrolling code. ++ + Cursor positioning in H, M, L, G (first non-blank for 1G) wasn't ++ being done correctly. Delete the SETLFNB flag. H, M, and L stay ++ logical movements (SETNNB) and G always moves to the first nonblank. ++ + System V uses "lines" and "cols", not "li" and "co", change as ++ necessary. Check termcap function returns for errors. ++ + Fix `<character> command to do start/end of line correction, ++ and to set line mode if starting and stopping at column 0. ++ + Fix bug in delete code where dropped core if deleted in character ++ mode to an empty line.

We have already seen how {3x} deletes three characters, and {22G} moves ++us to line 22 of the file. For almost all of the commands, one can survive by ++thinking of these leading numbers as a 'repeat count' specifying that the ++command is to be repeated so many number of times. ++ ++Other commands use the repeat count slightly differently, like the {G} command ++which use it as a line number. ++ ++For example: ++ ++{3^D} means scroll down in the file three lines. Subsequent {^D} OR {^U} will ++scroll only three lines in their respective directions! ++ ++{3z^M} says put line three of the file at the top of the screen, while {3z.} ++says put line three as close to the middle of the screen as possible. ++ ++{50|} moves the cursor to column fifty in the current line. ++ ++{3^F} says move forward 3 screenfulls. This is a repetition count. The ++documents advertise that {3^B} should move BACK three screenfulls, but I ++can't get it to work. ++ ++Position the cursor on some text and try {3r.}. This replaces three characters ++with '...'. However, {3s.....^[} is the same as {3xi.....^[}. ++ ++Try {10a+----^[}. ++ ++A very useful instance of a repetition count is one given to the '.' command, ++which repeats the last 'change' command. If you {dw} and then {3.}, you will ++delete first one and then three words. You can then delete two more words with ++{2.}. If you {3dw}, you will delete three words. A subsequent {.} will delete ++three more words. But a subsequent {2.} will delete only two words, not three ++times two words. ++ ++Caveat: The author has noticed that any repetition count with {^B} will NOT ++work: indeed, if you are at the end of your file and try {3^B} sufficiently ++often, the editor will hang you in an infinite loop. Please don't try it: ++take my word for it. ++ ++Section 28: {t} {T} {|} ++ ++Position the cursor on line 13 below: ++ ++Line 13: Four score and seven years ago, our forefathers brought ... ++ ++Note that {fv} moves the cursor on/over the 'v' in 'seven'. Do a {0} to return ++to the beginning of the line and try a {tv}. The cursor is now on/over the ++first 'e' in 'seven'. The {f} command finds the next occurrence of the ++specified letter and moves the cursor to it. The {t} command finds the ++specified letter and moves the cursor to the character immediately preceding ++it. {T} searches backwards, as does {F}. ++ ++Now try {60|}: the cursor is now on the 'o' in 'brought', which is the ++sixtieth character on the line. ++ ++Section 29: {d} {c} ++ ++Due to their complexity we have delayed discussion of two of the most powerful ++operators in vi until now. Effective use of these operators requires more ++explanation than was deemed appropriate for the first half of the tutorial. ++ ++{d} and {c} are called operators instead of commands because they consist of ++three parts: a count specification or a buffer specification (see section ++#BUFFERS), the {d} or {c}, and the object or range description. We will not ++discuss buffers at this stage, but will limit ourselves to count ++specifications. Examples speak louder than words: position the cursor at the ++beginning of line 14: ++ ++Line 14: Euclid alone has looked on beauty bear. ++ ++Obviously, there is something wrong with this quotation. Type {2fb} to ++position the cursor on the 'b' of 'bear'. Now, type {cwbare^[} ++and observe the results. The {cw} specifies that the change command {c} is to ++operate on a word object. More accurately, it specifies that the range of the ++change command includes the next word. ++ ++Position the cursor on the period in Line 14. (one way is to use {f.}) ++Now, type {cbbeast^[}. This specifies the range of the change command to be the ++previous word (the 'b' reminiscent of the {b} command). If we had wished to ++delete the word rather than change it, we would have used the {d} operator, ++rather than the {c} operator. ++ ++Position the cursor at the beginning of the line with {0}. Type ++{d/look/^M}. The search string specified the range of the delete. ++Everything UP TO the word 'looking' was deleted from the line. ++ ++In general, almost any command that would move the cursor will specify a range ++for these commands. The most confusing exception to this rule is when {dd} or ++{cc} is entered: they refer to the whole line. Following is a summary of the ++suffixes (suffices? suffici?) and the ranges they specify: ++ ++ suffix will delete{d}/change{c} ++ ------ ------------------------ ++ ^[ cancels the command ++ w the word to the right of the cursor ++ W ditto, but ignoring punctuation ++ b the word to the left of the cursor ++ B ditto, but ignoring punctuation ++ e see below. ++ E ditto ++ (space) a character ++ $ to the end of the line ++ ^ to the beginning of the line ++ / .. / up to, but not including, the string ++ ? .. ? back to and including the string ++ fc up to and including the occurrence of c ++ Fc back to and including the occurrence of c ++ tc up to but not including the occurrence of c ++ Tc back to but not including the occurrence of c ++ ^M TWO lines (that's right: two) ++ (number)^M that many lines plus one ++ (number)G up to and including line (number) ++ ( the previous sentence if you are at the beginning of ++ the current sentence, or the current sentence up to where ++ you are if you are not at the beginning of the current ++ sentence. Here, 'sentence' refers to the intuitive ++ notion of an English sentence, ending with '!', '?', ++ or '.' and followed by an end of line or two spaces. ++ ) the rest of the current sentence ++ { analogous to '(', but in reference to paragraphs: ++ sections of text surrounded by blank lines ++ } analogous to ')', but in reference to paragraphs ++ [[ analogous to '(', but in reference to sections ++ ]] analogous to ')', but in reference to sections ++ H the first line on the screen ++ M the middle line on the screen ++ L the last line on the screen ++ 3L through the third line from the bottom of the screen ++ ^F forward a screenful ++ ^B backward a screenful ++ : ++ : etc. etc. etc. ++ ++This list is not exhaustive, but it should be sufficient to get the idea ++across: after the {c} or {d} operator, you can specify a range with another ++move-the-cursor command, and that is the region of text over which the command ++will be effective. ++ ++Section 30: updating the screen {^R} ++ ++Vi tries to be very intelligent about the type of terminal you are working on ++and tries to use the in-terminal computing power (if any) of your terminal. ++Also if the terminal is running at a low baud rate (say 1200 or below), vi sets ++various parameters to make things easier for you. For example, if you were ++running on a 300 baud terminal (that's 30 characters per second transmission ++rate) not all 24 lines of the screen would be used by vi. In addition, there ++is a large portion of the editor keeping track of what your screen currently ++looks like, and what it would look like after a command has been executed. Vi ++then compares the two, and updates only those portions of the screen that have ++changed. ++ ++Furthermore, some of you may have noticed (it depends on your terminal) that ++deleting lines or changing large portions of text may leave some lines on the ++screen looking like: ++@ ++meaning that this line of the screen does not correspond to any line in your ++file. It would cost more to update the line than to leave it blank for the ++moment. If you would like to see your screen fully up-to-date with the ++contents of your file, type {^R}. ++ ++To see it in action, delete several lines with {5dd}, type {^R}, and then type ++{u} to get the lines back. ++ ++Here is as good a place as any to mention that if the editor is displaying the ++end of your file, there may be lines on the screen that look like: ++~ ++indicating that that screen line would not be affected by {^R}. These lines ++simply indicate the end of the file. ++ ++Section 31: text buffers {"} ++ ++Vi gives you the ability to store text away in "buffers". This feature is very ++convenient for moving text around in your file. There are a total of thirty- ++five buffers available in vi. There is the "unnamed" buffer that is used by all ++commands that delete text, including the change operator {c}, the substitute ++and replace commands {s} and {r}, as well as the delete operator {d} and delete ++commands {x} and {X}. This buffer is filled each time any of these commands ++are used. However, the undo command {u} has no effect on the unnamed buffer. ++ ++There are twenty-six buffers named 'a' through 'z' which are available for the ++user. If the name of the buffer is capitalized, then the buffer is not ++overwritten but appended to. For example, the command {"qdd} will delete one ++line and store that line in the 'q' buffer, destroying the previous contents of ++the buffer. However, {"Qdd} will delete one line of text and append that line ++to the current contents of the 'q' buffer. ++ ++Finally, there are nine buffers named '1' through '9' in which the last nine ++deletes are stored. Buffer 1 is the default buffer for the modify commands and ++is sometimes called the unnamed buffer. ++ ++To reference a specific buffer, use the double-quote command {"} followed by ++the name of the buffer. The next two sections show how buffers can be used to ++advantage. ++ ++Section 32: rearranging and duplicating text: {y} {Y} {p} {P} ++ ++Position yourself on line 15 below and {z^M}: ++ ++Line 15: A tree as lovely as a poem ... ++Line 16: I think that I shall never see ++ ++Type {dd}. Line 15 has disappeared and been replaced with the empty line (one ++with the single character @ on it) or (again depending on your terminal) Line ++16 has moved up and taken its place. We could recover Line 15 with an undo ++{u} but that would simply return it to its original location. Obviously, the ++two lines are reversed, so we want to put line 15 AFTER line 16. This is ++simply done with the put command {p}, which you should type now. What has ++happened is that {dd} put Line 15 into the unnamed buffer, and the {p} command ++retrieved the line from the unnamed buffer. ++ ++Now type {u} and observe that Line 15 disappears again (the put was undone ++without affecting the unnamed buffer). Type {P} and see that the capital {P} ++puts the line BEFORE the cursor. ++ ++To get Line 15 where it belongs again type {dd}{p}. ++ ++Also in Line 15 note that the words 'tree' and 'poem' are reversed. Using the ++unnamed buffer again: {ft}{dw}{ma}{fp}{P}{w}{dw}{`aP} will set things aright ++(note the use of the reverse quote). ++ ++The put commands {p} and {P} do not affect the contents of the buffer. ++Therefore, multiple {p} or {P} will put multiple copies of the unnamed buffer ++into your file. ++ ++Experiment with {d} and {p} on words, paragraphs, etc. Whatever {d} ++deletes, {p} can put. ++ ++Position the cursor on Line 17 and {z^M}: ++ ++Line 17: interest apple cat elephant boy dog girl hay farmer ++ ++Our task is to alphabetize the words on line 17. With the named buffers (and a ++contrived example) it is quite easy: ++ ++{"idw}{"adw}{"cdw}{"edw}{"bdw}{"ddw}{"gdw}{"hdw}{"fdw} ++ ++stores each of the words in the named buffer corresponding to the first letter ++of each of the words ('interest' goes in buffer "i, 'apple' goes in buffer "a, ++etc.). Now to put the words in order type: ++ ++{"ap$}{"bp$}{"cp$}{"dp$}{"ep$}{"fp$}{"gp$}{"hp$}{"ip$} ++ ++Notice that, because 'farmer' was at the end of the line, {dw} did not include ++a space after it, and that, therefore, there is no space between 'farmer' and ++'girl'. This is corrected with {Fg}{i ^[}. ++ ++This example could have been done just as easily with lines as with ++words. ++ ++You do not have to delete the text in order to put it into a buffer. If all ++you wish to do is to copy the text somewhere else, don't use {d}, rather use ++the yank commands {y} or {Y}. {y} is like {d} and {c} - an operator rather ++than a command. It, too, takes a buffer specification and a range ++specification. Therefore, instead of {dw}{P} to load the unnamed buffer with a ++word without deleting the word, use {yw} (yank a word). ++ ++{Y} is designed yank lines, and not arbitrary ranges. That is, {Y} is ++equivalent to {yy} (remember that operators doubled means the current line), ++and {3Y} is equivalent to {3yy}. ++ ++If the text you yank or modify forms a part of a line, or is an object such as ++a sentence which partially spans more than one line, then when you put the text ++back, it will be placed after the cursor (or before if you use {P}). If the ++yanked text forms whole lines, they will be put back as whole lines, without ++changing the current line. In this case, the put acts much like the {o} or {O} ++command. ++ ++The named buffers "a through "z are not affected by changing edit files. ++However, the unnamed buffer is lost when you change files, so to move text from ++one file to another you should use a named buffer. ++ ++Section 33: recovering lost lines ++ ++Vi also keeps track of the last nine deletes, whether you ask for it or not. ++This is very convenient if you would like to recover some text that was ++accidentally deleted or modified. Position the cursor on line 18 following, ++and {z^M}. ++ ++ ++Line 18: line 1 ++Line 19: line 2 ++Line 20: line 3 ++Line 21: line 4 ++Line 22: line 5 ++Line 23: line 6 ++Line 24: line 7 ++Line 25: line 8 ++Line 26: line 9 ++Type {dd} nine times: now don't cheat with {9dd}! That is totally different. ++ ++The command {"1p} will retrieve the last delete. Furthermore, when the ++numbered buffers are used, the repeat-command command {.} will increment the ++buffer numbers before executing, so that subsequent {.} will recover all nine ++of the deleted lines, albeit in reverse order. If you would like to review the ++last nine deletes without affecting the buffers or your file, do an undo {u} ++after each put {p} and {.}: ++ ++{"1p}{u}{.}{u}{.}{u}{.}{u}{.}{u}{.}{u}{.}{u}{.}{u}{.} ++ ++will show you all the buffers and leave them and your file intact. ++ ++If you had cheated above and deleted the nine lines with {9dd}, all nine lines ++would have been stored in both the unnamed buffer and in buffer number 1. ++(Obviously, buffer number 1 IS the unnamed buffer and is just the default ++buffer for the modify commands.) ++ ++Section 34: advanced file manipulation: {:r} {:e} {:n} {:w} {!} {:!} ++ ++We've already looked at writing out the file you are editing with the ++{:w} command. Now let's look at some other vi commands to make editing ++more efficient. ++ ++Section 34.1: more than one file at a time {:n} {:args} ++ ++Many times you will want to edit more than one file in an editing session. ++Instead of entering vi and editing the first file, exiting, entering vi and ++editing the second, etc., vi will allow you to specify ALL files that you wish ++to edit on the invocation line. Therefore, if you wanted to edit file1 and ++file2: ++ ++% vi file1 file2 ++ ++will set up file1 for editing. When you are done editing file one, write it ++out {:w^M} and then type {:n^M} to get the next file on the list. On large ++programming projects with many source files, it is often convenient just to ++specify all source files with, say: ++ ++% vi *.c ++ ++If {:n^M} brings in a file that does not need any editing, another {:n^M} ++will bring in the next file. ++ ++If you have made changes to the first file, but decide to discard these changes ++and proceed to the next file, {:n!^M} forces the editor to discard the current ++contents of the editor. ++ ++You can specify a new list of files after {:n}; e.g., {:n f1 f2 f3^M}. This ++will replace the current list of files (if any). ++ ++You can see the current list of files being edited with {:args^M}. ++ ++Section 34.2: reading files and command output: {:r} ++ ++Typing {:r fname^M} will read the contents of file fname into the editor and ++put the contents AFTER the cursor line. ++ ++Typing {:r !cmd^M} will read the output of the command cmd and place that ++output after the cursor line. ++ ++Section 34.3: invoking vi from within vi: {:e} {:vi} ++ ++To edit another file not mentioned on the invocation line, type {:e filename^M} ++or {:vi filename^M}. If you wish to discard the changes to the current file, ++use the exclamation point after the command, e.g. {:e! filename^M}. ++ ++Section 34.4: escaping to a shell: {:sh} {:!} {^Z} ++ ++Occasionally, it is useful to interrupt the current editing session to perform ++a UNIX task. However, there is no need to write the current file out, exit ++the editor, perform the task, and then reinvoke the editor on the same file. ++One thing to do is to spin off another process. If there are several UNIX ++commands you will need to execute, simply create another shell with {:sh^M}. ++At this point, the editor is put to sleep and will be reawakened when you log ++out of the shell. ++ ++If it is a single command that you want to execute, type {:!cmd^M}, where cmd ++is the command that you wish to run. The output of the command will come to ++the terminal as normal, and will not be made part of your file. The message ++"[Hit return to continue]" will be displayed by vi after the command is ++finished. Hitting return will then repaint the screen. Typing another ++{:!cmd^M} at this point is also acceptable. ++ ++However, there is a quicker, easier way: type {^Z}. Now this is a little ++tricky, but hang in there. When you logged into UNIX, the first program you ++began communicating with was a program that is called a "shell" (i.e. it 'lays ++over' the operating system protecting you from it, sort of like a considerate ++porcupine). When you got your first prompt on the terminal (probably a '%' ++character) this was the shell telling you to type your first command. When ++you typed {vi filename} for some file, the shell did not go away, it just went ++to sleep. The shell is now the parent of vi. When you type {^Z} the editor ++goes to sleep, the shell wakes up and says "you rang?" in the form of another ++prompt (probably '%'). At this point you are talking to the shell again and ++you can do anything that you could before including edit another file! (The ++only thing you can't do is log out: you will get the message "There are ++stopped jobs.") ++ ++When your business with the shell is done, type {fg} for 'foreground' and the ++last process which you ^Z'd out of will be reawakened and the shell will go ++back to sleep. I will refer you to the documentation for the Berkeley shell ++'csh' for more information on this useful capability. ++ ++Section 34.5: writing parts of a file: {:w} ++ ++The {:w} command will accept a range specifier that will then write only a ++selected range of lines to a file. To write this section to a file, position ++the cursor on the section line (e.g. {/^Section 34.5:/^M}) and {z^M}. Now type ++{^G} to find out the line number (it will be something like "line 513"). Now ++{/^Section 34.6:/-1^M} to find the last line of this section, and {^G} to find ++its line number (it will be something like 542). To write out this section of ++text by itself to a separate file which we will call "sepfile", type ++{:510,542w sepfile^M}. If sepfile already exists, you will have to use the ++exclamation point: {:1147,1168w! sepfile^M} or write to a different, non- ++existent file. ++ ++{:!cat sepfile^M} will display the file just written, and it should be the ++contents of this section. ++ ++There is an alternate method of determining the line numbers for the write. ++{:set number^M} will repaint the screen with each line numbered. When the file ++is written and the numbers no longer needed, {:set nonumber^M} will remove the ++numbers, and {^R} will adjust the screen. ++ ++Or, if you remember your earlier lessons about marking lines of text, ++mark the beginning and ending lines. Suppose we had used {ma} to mark the ++first line of the section and {mb} to mark the last. Then the command ++{:'a,'bw sepfile^M} will write the section into "sepfile". In general, ++you can replace a line number with the 'name' of a marked line (a single-quote ++followed by the letter used to mark the line) ++ ++ ++Section 34.6: filtering portions of text: {!} ++ ++{!} is an operator like {c} and {d}. That is, it consists of a repetition ++count, {!}, and a range specifier. Once the {!} operator is entered in its ++entirety, a prompt will be given at the bottom of the screen for a UNIX ++command. The text specified by the {!} operator is then deleted and ++passed/filtered/piped to the UNIX command you type. The output of the UNIX ++command is then placed in your file. For example, place the cursor at the ++beginning of the following line and {z^M}: ++ ++ls -l vi.tutorial ++********* marks the bottom of the output from the ls command ********** ++ ++Now type {!!csh^M}. The line will be replaced with the output from the ls ++command. The {u} command works on {!}, also. ++ ++Here is an extended exercise to display some of these capabilities. When this ++tutorial was prepared, certain auxiliary programs were created to aid in its ++development. Of major concern was the formatting of sections of the tutorial ++to fit on a single screen, particularly the first few sections. What was ++needed was a vi command that would 'format' a paragraph; that is, fill out ++lines with as many words as would fit in eighty columns. There is no such vi ++command. Therefore, another method had to be found. ++ ++Of course, nroff was designed to do text formatting. However, it produces a ++'page'; meaning that there may be many blank lines at the end of a formatted ++paragraph from nroff. The awk program was used to strip these blank lines from ++the output from nroff. Below are the two files used for this purpose: I refer ++you to documentation on nroff and awk for a full explanation of their function. ++Position the cursor on the next line and {z^M}. ++ ++******** contents of file f ********** ++# ++nroff -i form.mac | awk "length != 0 { print }" ++***** contents of file form.mac ****** ++.na ++.nh ++.ll 79 ++.ec ++.c2 ++.cc ++************************************** ++ ++Determine the line numbers of the two lines of file f. They should be ++something like 574 and 575, although you better double check: this file is ++under constant revision and the line numbers may change inadvertently. Then ++{:574,575w f^M}. Do the same for the lines of file form.mac. They will be ++approximately 577 and 582. Then {:577,582w form.mac^M}. File f must have ++execute privileges as a shell file: {:!chmod 744 f^M}. ++ ++Observe that this paragraph is ++rather ratty in appearance. With our newly created files we can ++clean it up dramatically. Position the cursor at the beginning ++of this paragraph and type the following sequence of ++characters ++(note that we must abandon temporarily our convention ++of curly braces since the command itself contains a curly brace - we ++will use square brackets for the nonce): [!}f^M]. ++ ++Here is a brief explanation of what has happened. By typing [!}f^M] we ++specified that the paragraph (all text between the cursor and the first blank ++line) will be removed from the edit file and piped to a UNIX program called ++"f". This is a shell command file that we have created. This shell file runs ++nroff, pipes its output to awk to remove blank lines, and the output from awk ++is then read back into our file in the place of the old, ratty paragraph. The ++file form.mac is a list of commands to nroff to get it to produce paragraphs ++to our taste (the right margin is not justified, the line is 79 characters ++long, words are not hyphenated, and three nroff characters are renamed to ++avoid conflict: note that in this file, the {^G} you see there is vi's display ++of the control-G character, and not the two separate characters ^ up-arrow and ++G upper-case g). ++ ++This example was created before the existence of the fmt program. I now type ++[!}fmt^M] to get the same effect much faster. Actually, I don't type those ++six keys each time: I have an abbreviation (which see). ++ ++Section 35: searching with magic patterns ++ ++The documentation available for "magic patterns" (i.e. regular expressions) is ++very scanty. The following should explain this possibly very confusing feature ++of the editor. This section assumes that the magic option is on. To make ++sure, you might want to type {:set magic^M}. ++ ++By "magic pattern" we mean a general description of a piece of text that the ++editor attempts to find during a search. Most search patterns consist of ++strings of characters that must be matched exactly, e.g. {/card/^M} searches ++for a specific string of four characters. Let us suppose that you have ++discovered that you consistently have mistyped this simple word as either ccrd ++or czrd (this is not so far-fetched for touch typists). You could {/ccrd/^M} ++and {n} until there are no more of this spelling, followed by {/czrd/^M} and ++{n} until there are no more of these. Or you could {/c.rd/^M} and catch all of ++them on the first pass. Try typing {/c.rd/^M} followed by several {n} and ++observe the effect. ++ ++Line 27: card cord curd ceard ++ ++When '.' is used in a search string, it has the effect of matching any single ++character. ++ ++The character '^' (up-arrow) used at the beginning of a search string means ++the beginning of the line. {/^Line 27/^M} will find the example line above, ++while {/Line 27/^M} will find an occurrence of this string anywhere in the ++line. ++ ++Similarly, {/ the$/^M} will find all occurrences of the word 'the' occurring ++at the end of a line. There are several of them in this file. ++ ++Note that {:set nomagic^M} will turn off the special meaning of these magic ++characters EXCEPT for '^' and '$' which retain their special meanings at the ++beginning and end of a search string. Within the search string they hold no ++special meaning. Try {/\/ the$\//^M} and note that the dollar-sign is not the ++last character in the search string. Let the dollar-sign be the last ++character in the search string, as in {/\/ the$/^M} and observe the result. ++ ++Observe the result of {/back.*file/^M}. This command, followed by sufficient ++{n}, will show you all lines in the file that contain both the words 'back' ++and 'file' on the same line. The '*' magic character specifies that the ++previous regular expression (the '.' in our example) is to be repeatedly ++matched zero or more times. In our example we specified that the words 'back' ++and 'file' must appear on the same line (they may be parts of words such as ++'backwards' or 'workfile') separated by any number (including zero) of ++characters. ++ ++We could have specified that 'back' and 'file' are to be words by themselves by ++using the magic sequences '\<' or '\>'. E.g. {/\<back\>.*\<file\>/^M}. The ++sequence '\<' specifies that this point of the search string must match the ++beginning of a word, while '\>' specifies a match at the end of a word. By ++surrounding a string with these characters we have specified that they must be ++words. ++ ++To find all words that begin with an 'l' or a 'w', followed by an 'a' or an ++'e', and ending in 'ing', try {/\<[lw][ea][a-z]*ing\>/^M}. This will match ++words like 'learning', 'warning', and 'leading'. The '[..]' notation matches ++exactly ONE character. The character matched will be one of the characters ++enclosed in the square brackets. The characters may be specified individually ++as in [abcd] or a '-' may be used to specify a range of characters as in [a-d]. ++That is, [az] will match the letter 'a' OR the letter 'z', while [a-z] will ++match any of the lower case letters from 'a' through 'z'. If you would like to ++match either an 'a', a '-', or a 'z', then the '-' must be escaped: [a\-z] will ++match ONE of the three characters 'a', '-', or 'z'. ++ ++If you wish to find all Capitalized words, try {/\<[A-Z][a-z]*\>/^M}. The ++following will find all character sequences that do NOT begin with an ++uncapitalized letter by applying a special meaning to the '^' character in ++square brackets: {/\<[^a-z][a-z]*\>/^M}. When '^' is the first character of a ++square-bracket expression, it specifies "all but these characters". (No ++one claimed vi was consistent.) ++ ++To find all variable names (the first character is alphabetic, the remaining ++characters are alphanumeric): try {/\<[A-Za-z][A-Za-z0-9]*\>/^M}. ++ ++In summary, here are the primitives for building regular expressions: ++ ++ ^ at beginning of pattern, matches beginning of line ++ $ at end of pattern, matches end of line ++ . matches any single character ++ \< matches the beginning of a word ++ \> matches the end of a word ++ [str] matches any single character in str ++ [^str] matches any single character NOT in str ++ [x-y] matches any character in the ASCII range between x and y ++ * matches any number (including zero) of the preceding pattern ++ ++Section 36: advanced substitution: {:s} ++ ++The straightforward colon-substitute command looks like the substitute ++command of most line-oriented editors. Indeed, vi is nothing more than a ++superstructure on the line-oriented editor ex and the colon commands are ++simply a way of accessing commands within ex (see section #EX). This gives us ++a lot of global file processing not usually found in visual oriented editors. ++ ++The colon-substitute command looks like: {:s/ .. / .. /^M} and will find the ++pattern specified after the first slash (this is called the search pattern), ++and replace it with the pattern specified after the second slash (called, ++obviously enough, the replacement pattern). E.g. position the cursor on line ++28 below and {:s/esample/example/^M}: ++ ++Line 28: This is an esample. ++ ++The {u} and {U} commands work for {:s}. The first pattern (the search pattern) ++may be a regular expression just as for the search command (after all, it IS a ++search, albeit limited to the current line). Do an {u} on the above line, and ++try the following substitute, which will do almost the same thing: ++{:s/s[^ ]/x/^M}. ++Better undo it with {u}. The first pattern {s[^ ]} matches an 's' ++NOT followed by a blank: the search therefore ignores the 's'es in 'This' and ++'is'. However, the character matched by {[^ ]} must appear in the replacement ++pattern. But, in general, we do not know what that character is! (In this ++particular example we obviously do, but more complicated examples will follow.) ++Therefore, vi (really ex) has a duplication mechanism to copy patterns matched ++in the search string into the replacement string. Line 29 below is a copy of ++line 28 above so you can adjust your screen. ++ ++Line 29: This is an esample. ++ ++In general, you can nest parts of the search pattern in \( .. \) and refer to ++it in the replacement pattern as \n, where n is a digit. The problem outlined ++in the previous paragraph is solved with {:s/s\([^ ]\)/x\1/^M}: try it. Here ++\1 refers to the first pattern grouping \( .. \) in the search string. ++ ++Obviously, for a single line, this is rather tedious. Where it becomes ++powerful, if not necessary, is in colon-substitutes that cover a range of ++lines. (See the next section for a particularly comprehensive example.) ++ ++If the entire character sequence matched by the search pattern is needed in ++the replacement pattern, then the unescaped character '&' can be used. On ++Line 29 above, try {:s/an e.ample/not &/^M}. If another line is to have the ++word 'not' prepended to a pattern, then '~' can save you from re-typing the ++replacement pattern. E.g. {:s/some pattern/~/^M} after the previous example ++would be equivalent to {:s/some pattern/not &/^M}. ++ ++One other useful replacement pattern allows you to change the case of ++individual letters. The sequences {\u} and {\l} cause the immediately ++following character in the replacement to be converted to upper- or lower-case, ++respectively, if this character is a letter. The sequences {\U} and {\L} turn ++such conversion on, either until {\E} or {\e} is encountered, or until the end ++of the replacement pattern. ++ ++For example, position the cursor on a line: pick a line, any line. Type ++{:s/.*/\U&/^M} and observe the result. You can undo it with {u}. ++ ++The search pattern may actually match more than once on a single line. ++However, only the first pattern is substituted. If you would like ALL ++patterns matched on the line to be substituted, append a 'g' after the ++replacement pattern: {:s/123/456/g^M} will substitute EVERY occurrence ++on the line of 123 with 456. ++ ++Section 37: advanced line addressing: {:p} {:g} {:v} ++ ++Ex (available through the colon command in vi) offers several methods for ++specifying the lines on which a set of commands will act. For example, if you ++would like to see lines 50 through 100 of your file: {:50,100p^M} will display ++them, wait for you to [Hit return to continue], and leave you on line 100. ++Obviously, it would be easier just to do {100G} from within vi. But ++what if you would like to make changes to just those lines? Then the ++addressing is important and powerful. ++ ++Line 30: This is a text. ++Line 31: Here is another text. ++Line 32: One more text line. ++ ++The lines above contain a typing error that the author of this tutorial tends ++to make every time he attempts to type the word 'test'. To change all of these ++'text's into 'test's, try the following: ++{:/^Line 30/,/^Line 32/s/text/test/^M}. This finds the beginning and end of ++the portion of text to be changed, and limits the substitution to each of the ++lines in that range. The {u} command applies to ALL of the substitutions as ++a group. ++ ++This provides a mechanism for powerful text manipulations. ++And very complicated examples. ++ ++Line 33: This test is a. ++Line 34: Here test is another. ++Line 35: One line more test. ++ ++The above three lines have the second word out of order. The following command ++string will put things right. Be very careful when typing this: it is very ++long, full of special characters, and easy to mess up. You may want to ++consider reading the following section to understand it before trying the ++experiment. Don't worry about messing up the rest of the file, though: the ++address range is specified. ++ ++{:/^Line 33/,/^Line 35/s/\([^:]*\): \([^ ]*\) \([^ ]*\) \([^.]*\)/\1: \2 \4 \3/^M} ++ ++There are several things to note about this command string. First of all, the ++range of the substitute was limited by the address specification {/^Line ++33/,/^Line 35/^M}. It might have been simpler to do {:set number^M} to see the ++line numbers directly, and then, in place of the two searches, typed ++the line numbers, e.g. {1396,1398}. Or to mark the lines with {ma} and {mb} ++and use {'a,'b}. ++ ++Then follows the substitute pattern itself. To make it easier to understand ++what the substitute is doing, the command is duplicated below with the various ++patterns named for easier reference: ++ ++ s/\([^:]*\): \([^ ]*\) \([^ ]*\) \([^.]*\)/\1: \2 \4 \3/ ++ |--\1---| |--\2---| |--\3---| |--\4---| ++ |--------search pattern------------------|-replacement| ++ |--pattern---| ++ ++In overview, the substitute looks for a particular pattern made up of ++sub-patterns, which are named \1, \2, \3, and \4. These patterns are specified ++by stating what they are NOT. Pattern \1 is the sequence of characters that ++are NOT colons: in the search string, {[^:]} will match exactly one character ++that is not a colon, while appending the asterisk {[^:]*} specifies that the ++'not a colon' pattern is to be repeated until no longer satisfied, and ++{\([^:]*\)} then gives the pattern its name, in this case \1. Outside of the ++specification of \1 comes {: }, specifying that the next two characters must be ++a colon followed by a blank. ++ ++Patterns \2 and \3 are similar, specifying character sequences that are ++not blanks. Pattern \4 matches up to the period at the end of the line. ++ ++The replacement pattern then consists of specifying the new order of the ++patterns. ++ ++This is a particularly complicated example, perhaps the most complicated ++in this tutorial/reference. For our small examples, it is obviously ++tedious and error prone. For large files, however, it may be the most ++efficient way to make the desired modifications. ++ ++(The reader is advised to look at the documentation for awk. This tool is very ++powerful and slightly simpler to use than vi for this kind of file ++manipulation. But, it is another command language to learn.) ++ ++Many times, you will not want to operate on every line in a certain ++range. Rather you will want to make changes on lines that satisfy ++certain patterns; e.g. for every line that has the string 'NPS' on it, ++change 'NPS' to 'Naval Postgraduate School'. The {:g} addressing ++command was designed for this purpose. The example of this paragraph ++could be typed as {:g/NPS/s//Naval Postgraduate School/^M}. ++ ++The general format of the command is {:g/(pattern)/cmds^M} and it ++works in the following way: all lines that match the pattern ++following the {:g} are 'tagged' in a special way. Then each of these ++lines have the commands following the pattern executed over them. ++ ++Line 36: ABC rhino george farmer Dick jester lest ++Line 37: george farmer rhino lest jester ABC ++Line 38: rhino lest george Dick farmer ABC jester ++ ++Type: ++ ++{:g/^Line.*ABC/s/Dick/Harry Binswanger/|s/george farmer/gentleman george/p^M} ++ ++There are several things of note here. First, lines 36, 37, and 38 above are ++tagged by the {:g}. Type {:g/^Line.*ABC/p^M} to verify this. Second, there ++are two substitutes on the same line separated by '|'. In general, any colon ++commands can be strung together with '|'. Third, both substitutes operate on ++all three lines, even though the first stubstitute works on only two of the ++lines (36 and 38). Fourth, the second substitute works on only two lines (36 ++and 37) and those are the two lines printed by the trailing 'p'. ++ ++The {:v} command works similarly to the {:g} command, except that the sense of ++the test for 'tagging' the lines is reversed: all lines NOT matching the search ++pattern are tagged and operated on by the commands. ++ ++Using {^V} to quote carriage return (see section 39) can be used in global ++substitutions to split two lines. For example, the command ++{:g/\. /s//.^V^M/g^M} will change your file so that each sentence is on a ++separate line. (Note that we have to 'escape' the '.', because '.' by itself ++matches any character. Our command says to find any line which contains a ++period followed by 2 spaces, and inserts a carriage return after the period.) ++ ++Caveat: In some of the documentation for ex and vi you may find the ++comment to the effect that {\^M} can be used between commands following ++{:g}. The author of this tutorial has never gotten this to work and has ++crashed the editor trying. ++ ++Section 38: higher level text objects and nroff: {(} {)} [{] [}] {[[} {]]} ++ ++(Note: this section may be a little confusing because of our command ++notation. Using curly braces to surround command strings works fine as ++long as the command string does not contain any curly braces itself. ++However, the curly braces are legitimate commands in vi. Therefore, for ++any command sequence that contains curly braces, we will surround that ++sequence with SQUARE braces, as on the previous Section line.) ++ ++In working with a document, particularly if using the text formatting ++programs nroff or troff, it is often advantageous to work in terms of ++sentences, paragraphs, and sections. The operations {(} and {)} move to ++the beginning of the previous and next sentences, respectively. Thus ++the command {d)} will delete the rest of the current sentence; likewise ++{d(} will delete the previous sentence if you are at the beginning of ++the current sentence, or, if you are not at the beginning of a sentence, ++it will delete the current sentence from the beginning ++up to where you are. ++ ++A sentence is defined to end at a '.', '!', or '?' which is followed ++by either the end of a line, or by two spaces. Any number of closing ++')', ']', '"', and ''' characters may appear after the '.', '!', or '?' ++before the spaces or end of line. Therefore, the {(} and {)} commands ++would recognize only one sentence in the following line, but two ++sentences on the second following line. ++ ++Line 39: This is one sentence. Even though it looks like two. ++Line 40: This is two sentences. Because it has two spaces after the '.'. ++ ++The operations [{] and [}] move over paragraphs and the operations {[[} ++and {]]} move over sections. ++ ++A paragraph begins after each empty line, and also at each of a set of nroff ++paragraph macros. A section begins after each line with a form-feed ^L in the ++first column, and at each of a set of nroff section macros. When preparing a ++text file as input to nroff, you will probably be using a set of nroff macros ++to make the formatting specifications easier, or more to your taste. These ++macros are invoked by beginning a line with a period followed by the one or two ++letter macro name. Vi has been programmed to recognize these nroff macros, and ++if it doesn't recognize your particular macro you can use the {:set paragraphs} ++or {:set sections} commands so that it will. ++ ++Section 39: more about inserting text ++ ++There are a number of characters which you can use to make correnctions ++during input mode. These are summarized in the following table. ++ ++ ^H deletes the last input character ++ ^W deletes the last input word ++ (erase) same as ^H; each terminal can define its own erase character; ++ for some it is ^H, for others it is the DELETE key, and for ++ others it is '@'. ++ (kill) deletes the input on this line; each terminal can define its ++ own line-kill character; for some it is ^U, for others it is ++ '@'; you will need to experiment on your terminal to find ++ out what your line-kill and erase characters are. ++ \ escapes a following ^H, (kill), and (erase) characters: i.e. ++ this is how to put these characters in your file. ++ ^[ escape key; ends insertion mode ++ ^? the delete key; interrupts an insertion, terminating it ++ abnormally. ++ ^M the return key; starts a new line. ++ ^D backtabs over the indentation set by the autoindent option ++ 0^D backtabs over all indentation back to the beginning of the line ++ ^^D (up-arrow followed by control-d)same as 0^D, except the indentation ++ will be restored at the beginning of the next line. ++ ^V quotes the next non-printing character into the file ++ ++If you wish to type in your erase or kill character (say # or @ or ^U) then you ++must precede it with a \, just as you would do at the normal system command ++level. A more general way of typing non-printing characters into the file is ++to precede them with a ^V. The ^V echoes as a ^ character on which the cursor ++rests. This indicates that the editor expects you to type a control character ++and it will be inserted into the file at that point. There are a few ++exceptions to note. The implementation of the editor does not allow the null ++character ^@ to appear in files. Also the linefeed character ^J is used by the ++editor to separate lines in the file, so it cannot appear in the middle of a ++line. (Trying to insert a ^M into a file, or putting it in the replacement ++part of a substitution string will result in the matched line being split in ++two. This, in effect, is how to split lines by using a substitution.) You can ++insert any other character, however, if you wait for the editor to echo the ^ ++before you type the character. In fact, the editor will treat a following ++letter as a request for the corresponding control character. This is the only ++way to type ^S or ^Q, since the system normally uses them to suspend and resume ++output and never gives them to the editor to process. ++ ++If you are using the autoindent option you can backtab over the indent which it ++supplies by typing a ^D. This backs up to the boundary specified by the ++shiftwidth option. This only works immediately after the supplied autoindent. ++ ++When you are using the autoindent option you may wish to place a label at the ++left margin of a line. The way to do this easily is to type ^ (up-arrow) and ++then ^D. The editor will move the cursor to the left margin for one line, and ++restore the previous indent on the next. You can also type a 0 followed ++immediately by a ^D if you wish to kill all indentation and not have it resume ++on the next line. ++ ++Section 40: more on operators: {d} {c} {<} {>} {!} {=} {y} ++ ++Below is a non-exhaustive list of commands that can follow the operators ++to affect the range over which the operators will work. However, note ++that the operators {<}, {>}, {!}, and {=} do not operate on any object ++less than a line. Try {!w} and you will get a beep. To get the ++operator to work on just the current line, double it. E.g. {<<}. ++ ++ suffix will operate on ++ ------ ------------------------ ++ ^[ cancels the command ++ w the word to the right of the cursor ++ W ditto, but ignoring punctuation ++ b the word to the left of the cursor ++ B ditto, but ignoring punctuation ++ e see below. ++ E ditto ++ (space) a character ++ $ to the end of the line ++ ^ to the beginning of the line ++ / .. / up to, but not including, the string ++ ? .. ? back to and including the string ++ fc up to and including the occurrence of c ++ Fc back to and including the occurrence of c ++ tc up to but not including the occurrence of c ++ Tc back to but not including the occurrence of c ++ ^M TWO lines (that's right: two) ++ (number)^M that many lines plus one ++ (number)G up to and including line (number) ++ ( the previous sentence if you are at the beginning of ++ the current sentence, or the current sentence up to where ++ you are if you are not at the beginning of the current ++ sentence.

Vi gives you the ability to specify an abbreviation for ++a long string such that typing the abbreviation will automatically ++expand into the longer phrase. ++ ++Type {:ab nps Naval Postgraduate School^M}. Now type: ++ ++{iThis is to show off the nps's UNIX editor.^M^[} ++ ++Section 42: vi's relationship with the ex editor: {:} ++ ++Vi is actually one mode of editing within the editor ex. When you are ++running vi you can escape to the line oriented editor of ex by giving ++the command {Q}. All of the colon-commands which were introduced above ++are available in ex. Likewise, most ex commands can be invoked from vi ++using {:}. ++ ++In rare instances, an internal error may occur in vi. In this case you ++will get a diagnostic and will be left in the command mode of ex. You can ++then save your work and quit if you wish by giving the command {x} after ++the colon prompt of ex. Or you can reenter vi (if you are brave) by ++giving ex the command {vi}. ++ ++Section 43: vi on hardcopy terminals and dumb terminals: open mode ++ ++(The author has not checked the following documentation for accuracy. It is ++abstracted from the Introduction to Vi Editing document.) ++ ++If you are on a hardcopy terminal or a terminal which does not have a cursor ++which can move off the bottom line, you can still use the command set of vi, ++but in a different mode. When you give the vi command to UNIX, the editor will ++tell you that it is using open mode. This name comes from the open command in ++ex, which is used to get into the same mode. ++ ++The only difference between visual mode (normal vi) and open mode is the way in ++which the text is displayed. ++ ++In open mode the editor uses a single line window into the file, and moving ++backward and forward in the file causes new lines to be displayed, always below ++the current line. Two commands of vi work differently in open: {z} and {^R}. ++The {z} command does not take parameters, but rather draws a window of context ++around the current line and then returns you to the current line. ++ ++If you are on a hardcopy terminal, the {^R} command will retype the current ++line. On such terminals, the editor normally uses two lines to represent the ++current line. The first line is a copy of the line as you started to edit it, ++and you work on the line below this line. When you delete characters, the ++editor types a number of \'s to show you the characters which are deleted. The ++editor also reprints the current line soon after such changes so that you can ++see what the line looks like again. ++ ++It is sometimes useful to use this mode on very slow terminals which can ++support vi in the full screen mode. You can do this by entering ex and using ++an {open} command. ++ ++********************************************************************* ++Section 44: options: {:set} {setenv EXINIT} ++ ++You will discover options as you need them. Do not worry about them very much ++on the first pass through this document. My advice is to glance through them, ++noting the ones that look interesting, ignoring the ones you don't understand, ++and try re-scanning them in a couple of weeks. ++ ++If you decide that you have a favorite set of options and would like to change ++the default values for the editor, place a {setenv EXINIT} command in your ++.login file. When you are given an account under UNIX your directory has ++placed in it a file that is executed each time you log in. If one of the ++commands in this file sets the environment variable EXINIT to a string of vi ++commands, you can have many things done for you each time you invoke vi. For ++example, if you decide that you don't like tabstops placed every eight columns ++but prefer every four columns, and that you wish the editor to insert linefeeds ++for you when your typing gets you close to column 72, and you want ++autoindentation, then include the following line in your .login file: ++ ++setenv EXINIT='set tabstop=4 wrapmargin=8 autoindent' ++ ++or equivalently ++ ++setenv EXINIT='se ts=4 wm=8 ai' ++ ++Each time you bring up vi, this command will be executed and the options set. ++ ++There are forty options in the vi/ex editor that the user can set for his/her ++own convenience. They are described in more detail in individual sections ++below. The section line will show the full spelling of the option name, the ++abbreviation, and the default value of the option. The text itself ++comes from the ex reference manual and is not the epitome of clarity. ++ ++Section 44.1: {autoindent}, {ai} default: noai ++ ++Can be used to ease the preparation of structured program text. At the ++beginning of each append, change or insert command or when a new line is opened ++or created by an append, change, insert, or substitute operation within open or ++visual mode, ex looks at the line being appended after, the first line changed ++or the line inserted before and calculates the amount of white space at the ++start of the line. It then aligns the cursor at the level of indentation so ++determined. ++ ++If the user then types lines of text in, they will continue to be justified at ++the displayed indenting level. If more white space is typed at the beginning ++of a line, the following line will start aligned with the first non-white ++character of the previous line. To back the cursor up to the preceding tab ++stop one can hit {^D}. The tab stops going backwards are defined at multiples ++of the shiftwidth option. You cannot backspace over the indent, except by ++sending an end-of-file with a {^D}. A line with no characters added to it ++turns into a completely blank line (the white space provided for the autoindent ++is discarded). Also specially processed in this mode are lines beginning with ++an up-arrow `^' and immediately followed by a {^D}. This causes the input to ++be repositioned at the beginning of the line, but retaining the previous indent ++for the next line. Similarly, a `0' followed by a {^D} repositions at the ++beginning but without retaining the previous indent. Autoindent doesn't happen ++in global commands or when the input is not a terminal. ++ ++Section 44.2: {autoprint}, {ap} default: ap ++ ++Causes the current line to be printed after each delete, copy, join, move, ++substitute, t, undo or shift command. This has the same effect as supplying a ++trailing `p' to each such command. Autoprint is suppressed in globals, and ++only applies to the last of many commands on a line. ++ ++Section 44.3: {autowrite}, {aw} default: noaw ++ ++Causes the contents of the buffer to be written to the current file if you have ++modified it and give a next, rewind, stop, tag, or {!} command, or a control- ++up-arrow {^^} (switch files) or {^]} (tag goto) command in visual. Note, that ++the edit and ex commands do not autowrite. In each case, there is an ++equivalent way of switching when autowrite is set to avoid the autowrite ++({edit} for next, rewind! for rewind, stop! for stop, tag! for tag, shell ++for {!}, and {:e #} and a {:ta!} command from within visual). ++ ++Section 44.4: {beautify}, {bf} default: nobeautify ++ ++Causes all control characters except tab ^I, newline ^M and form-feed ^L to be ++discarded from the input. A complaint is registered the first time a backspace ++character is discarded. Beautify does not apply to command input. ++ ++Section 44.5: {directory}, {dir} default: dir=/tmp ++ ++Specifies the directory in which ex places its buffer file. If this directory ++in not writable, then the editor will exit abruptly when it fails to be able to ++create its buffer there. ++ ++Section 44.6: {edcompatible} default: noedcompatible ++ ++Causes the presence or absence of g and c suffixes on substitute commands to be ++remembered, and to be toggled by repeating the suffices. The suffix r makes ++the substitution be as in the {~} command, instead of like {&}. ++ ++[Author's note: this should not concern users of vi.] ++ ++Section 44.7: {errorbells}, {eb} default: noeb ++ ++Error messages are preceded by a bell. However, bell ringing in open and ++visual modes on errors is not suppressed by setting noeb. If possible the ++editor always places the error message in a standout mode of the terminal (such ++as inverse video) instead of ringing the bell. ++ ++Section 44.8: {hardtabs}, {ht} default: ht=8 ++ ++Gives the boundaries on which terminal hardware tabs are set (or on which the ++system expands tabs). ++ ++Section 44.9: {ignorecase}, {ic} default: noic ++ ++All upper case characters in the text are mapped to lower case in regular ++expression matching. In addition, all upper case characters in regular ++expressions are mapped to lower case except in character class specifications ++(that is, character in square brackets). ++ ++Section 44.10: {lisp} default: nolisp ++ ++Autoindent indents appropriately for lisp code, and the {(}, {)}, [{], [}], ++{[[}, and {]]} commands in open and visual modes are modified in a ++striaghtforward, intuitive fashion to have meaning for lisp. ++ ++[Author's note: but don't ask me to define them precisely.] ++ ++Section 44.11: {list} default: nolist ++ ++All printed lines will be displayed (more) unambiguously, showing tabs as ^I ++and end-of-lines with `$'. This is the same as in the ex command {list}. ++ ++Section 44.12: {magic} default: magic for {ex} and {vi}, nomagic for edit. ++ ++If nomagic is set, the number of regular expression metacharacters is greatly ++reduced, with only up-arrow `^' and `$' having special effects. In addition ++the metacharacters `~' and `&' of the replacement pattern are treated as normal ++characters. All the normal metacharacters may be made magic when nomagic is ++set by preceding them with a `\'. ++ ++[Author's note: In other words, if magic is set a back-slant turns the magic ++off for the following character, and if nomagic is set a back-slant turns the ++magic ON for the following character. And, no, we are not playing Dungeons and ++Dragons, although I think the writers of these option notes must have played it ++all the time.] ++ ++Section 44.13: {mesg} default: mesg ++ ++Causes write permission to be turned off to the terminal while you are in ++visual mode, if nomesg is set. ++ ++[Author's note: I don't know if anyone could have made any one sentence ++paragraph more confusing than this one. What it says is: mesg allows people to ++write to you even if you are in visual or open mode; nomesg locks your terminal ++so they can't write to you and mess up your screen.] ++ ++Section 44.14: {number, nu} default: nonumber ++ ++Causes all output lines to be printed with their line numbers. In addition ++each input line will be prompted with its line number. ++ ++Section 44.15: {open} default: open ++ ++If {noopen}, the commands open and visual are not permitted. This is set for ++edit to prevent confusion resulting from accidental entry to open or visual ++mode. ++ ++[Author's note: As you may have guessed by now, there are actually three ++editors available under Berkeley UNIX that are in reality the same ++program, ex, with different options set: ex itself, vi, and edit.] ++ ++Section 44.16: {optimize, opt} default: optimize ++ ++Throughput of text is expedited by setting the terminal to not do automatic ++carriage returns when printing more than one (logical) line of output, greatly ++speeding output on terminals without addressable cursors when text with leading ++white space is printed. ++ ++[Author's note: I still don't know what this option does.] ++ ++Section 44.17: {paragraphs, para} default: para=IPLPPPQPP LIbp ++ ++Specifies the paragraphs for the [{] and [}] operations in open and visual. ++The pairs of characters in the option's value are the names of the nroff macros ++which start paragraphs. ++ ++Section 44.18: {prompt} default: prompt ++ ++Command mode input is prompted for with a `:'. ++ ++[Author's note: Doesn't seem to have any effect on vi.] ++ ++Section 44.19: {readonly}, {ro} default: noro, unless invoked with -R ++ or insufficient privileges on file ++ ++This option allows you to guarantee that you won't clobber your file by ++accident. You can set the option and writes will fail unless you use an `!' ++after the write. Commands such as {x}, {ZZ}, the autowrite option, and in ++general anything that writes is affected. This option is turned on if you ++invoke the editor with the -R flag. ++ ++Section 44.20: {redraw} default: noredraw ++ ++The editor simulates (using great amounts of output), an intelligent terminal ++on a dumb terminal (e.g. during insertions in visual the characters to the ++right of the cursor position are refreshed as each input character is typed). ++Useful only at very high baud rates, and should be used only if the system is ++not heavily loaded: you will notice the performance degradation yourself. ++ ++Section 44.21: {remap} default: remap ++ ++If on, macros are repeatedly tried until they are unchanged. For example, if o ++is mapped to O, and O is mapped to I, then if remap is set, o will map to I, ++but if noremap is set, it will map to O . ++ ++Section 44.22: {report} default: report=5 for ex and vi, 2 for edit ++ ++Specifies a threshold for feedback from commands. Any command which modifies ++more than the specified number of lines will provide feedback as to the scope ++of its changes. For commands such as global, open, undo, and visual which have ++potentially more far reaching scope, the net change in the number of lines in ++the buffer is presented at the end of the command, subject to this same ++threshold. Thus notification is suppressed during a global command on the ++individual commands performed. ++ ++Section 44.23: {scroll} default: scroll=1/2 window ++ ++Determines the number of logical lines scrolled when a {^D} is received from a ++terminal in command mode, and determines the number of lines printed by a ++command mode z command (double the value of scroll). ++ ++[Author's note: Doesn't seem to affect {^D} and {z} in visual (vi) mode.] ++ ++Section 44.24: sections {sections} default: sections=SHNHH HU ++ ++Specifies the section macros from nroff for the {[[} and {]]} operations in ++open and visual. The pairs of characters in the options's value are the names ++of the macros which start paragraphs. ++ ++Section 44.25: {shell}, {sh} default: sh=/bin/sh ++ ++Gives the path name of the shell forked for the shell escape command `!', and ++by the shell command. The default is taken from SHELL in the environment, if ++present. ++ ++[Editor's note: I would suggest that you place the following line in ++your .login file: ++setenv SHELL '/bin/csh' ++] ++ ++Section 44.26: {shiftwidth}, {sw} default: sw=8 ++ ++Used in reverse tabbing with {^D} when using autoindent to append text, and ++used by the shift commands. Should probably be the same value as the tabstop ++option. ++ ++Section 44.27: {showmatch}, {sm} default: nosm ++ ++In open and visual mode, when a `)' or `}' is typed, if the matching `(' or `{' ++is on the screen, move the cursor to it for one second. Extremely useful with ++complicated nested expressions, or with lisp. ++ ++Section 44.28: {slowopen}, {slow} default: terminal dependent ++ ++Affects the display algorithm used in visual mode, holding off display updating ++during input of new text to improve throughput when the terminal in use is both ++slow and unintelligent. See "An Introduction to Display Editing with Vi" for ++more details. ++ ++Section 44.29: {tabstop}, {ts} default: ts=8 ++ ++The editor expands tabs ^I to tabstop boundaries in the display. ++ ++Section 44.30: {taglength}, {tl} default: tl=0 ++ ++Tags are not significant beyond this many characters. ++A value of zero (the default) means that all characters are significant. ++ ++Section 44.31: {tags} default: tags=tags /usr/lib/tags ++ ++A path of files to be used as tag files for the tag command. A requested tag ++is searched for in the specified files, sequentially. By default files called ++tags are searched for in the current directory and in /usr/lib (a master file ++for the entire system). ++ ++[Author's note: The author of this tutorial has never used this option, nor ++seen it used. I'm not even sure I know what they are talking about.] ++ ++Section 44.32: {term} default: from environment variable TERM ++ ++The terminal type of the output device. ++ ++Section 44.33: {terse} default: noterse ++ ++Shorter error diagnostics are produced for the experienced user. ++ ++Section 44.34: {timeout} default: timeout ++ ++Causes macros to time out after one second. Turn it off and they will ++wait forever. This is useful if you want multi-character macros, but if ++your terminal sends escape sequences for arrow keys, it will be ++necessary to hit escape twice to get a beep. ++ ++[Editor's note: Another paragraph which requires a cryptographer.] ++ ++Section 44.35: ttytype ++ ++[Editor's note: I have found no documentation for this option at all.] ++ ++Section 44.36: {warn} default: warn ++ ++Warn if there has been `[No write since last change]' before a `!' command ++escape. ++ ++Section 44.37: {window} default: window=speed dependent ++ ++The number of lines in a text window in the visual command. The default is 8 ++at slow speeds (600 baud or less), 16 at medium speed (1200 baud), and the full ++screen (minus one line) at higher speeds. ++ ++Section 44.38: {wrapscan}, {ws} default: ws ++ ++Searches using the regular expressions in addressing will wrap around past the ++end of the file. ++ ++Section 44.39: {wrapmargin}, {wm} default: wm=0 ++ ++Defines a margin for automatic wrapover of text during input in open and visual ++modes. The numeric value is the number of columns from the right edge of the ++screen around which vi looks for a convenient place to insert a new-line ++character (wm=0 is OFF). This is very convenient for touch typists. ++Wrapmargin behaves much like fill/nojustify mode does in nroff. ++ ++Section 44.40: {writeany}, {wa} default: nowa ++ ++Inhibit the checks normally made before write commands, allowing a write to any ++file which the system protection mechanism will allow. ++ ++Section 44.41: {w300}, {w1200}, {w9600} defaults: w300=8 ++ w1200=16 ++ w9600=full screen minus one ++ ++These are not true options but set the default size of the window for when the ++speed is slow (300), medium (1200), or high (9600), respectively. They are ++suitable for an EXINIT and make it easy to change the 8/16/full screen rule. ++ ++Section 45: Limitations ++ ++Here are some editor limits that the user is likely to encounter: ++ 1024 characters per line ++ 256 characters per global command list ++ 128 characters per file name ++ 128 characters in the previous inserted and deleted text in open or ++ visual ++ 100 characters in a shell escape command ++ 63 characters in a string valued option ++ 30 characters in a tag name ++ 250000 lines in the file (this is silently enforced). ++ ++The visual implementation limits the number of macros defined with map to 32, ++and the total number of characters in macros to be less than 512. ++ ++[Editor's note: these limits may not apply to versions after 4.1BSD.] +diff -Naur nvi-1.81.orig/nvi-1.79/docs/tutorial/vi.beginner nvi-1.81.6/nvi-1.79/docs/tutorial/vi.beginner +--- nvi-1.81.6.orig/nvi-1.79/docs/tutorial/vi.beginner 1970-01-01 01:00:00.000000000 +0100 ++++ nvi-1.81.6/nvi-1.79/docs/tutorial/vi.beginner 2008-06-22 20:35:35.000000000 +0200 +@@ -0,0 +1,741 @@ ++Section 1: {^F} {ZZ} ++ ++To get out of this tutorial, type: ZZ (two capital Z's). ++ ++Learning a new computer system implies learning a new text editor. These ++tutorial lessons were created by Dain Samples to help you come to grips with ++UC Berkeley's screen oriented editor called vi (for VIsual). This tutorial ++uses the vi editor itself as the means of presentation. ++ ++For best use of this tutorial, read all of a screen before performing any of ++the indicated actions. This tutorial (or, at least, the first half of it) has ++been designed to systematically present the vi commands IF THE INSTRUCTIONS ++ARE FOLLOWED! If you are too adventuresome, you may find yourself lost. If ++you ever find yourself stuck, remember the first line of this section. ++ ++OK, now find the control key on your keyboard; it usually has CTL or CTRL ++written on its upper surface. Your first assignment is to hold the control ++key down while you press the 'F' key on your keyboard. Please do so now. ++ ++ ++ ++Section 2: {^F} {^B} ++Many of vi's commands use the control key and some other key in combination, ++as with the control and the 'F' key above. This is abbreviated CTL-F, or ^F. ++ ++As you have probably guessed by now, ^F (CTL-F) moves you forward a fixed ++number of lines in the file. Throughout the remainder of the tutorial when ++you are ready to advance to the next section of text, hit ^F. ++ ++The opposite command is ^B. Just for fun, you might want to try a ^B to see ++the previous section again. Be sure to do a ^F to return you here. ++ ++Determine what the cursor looks like on your screen. Whatever it is (a box, ++an underscore, blinking, flashing, inverse, etc.) it should now be positioned ++in the upper left-hand corner of your screen under or on the S of Section. ++Become familiar with your cursor: to use vi correctly it is important to ++always know where the cursor is. ++ ++Did you notice that when you do a ^F the cursor is left at the top of the ++screen, and a ^B leaves the cursor near the bottom of the screen? Try the two ++commands ^B^F again. And now do another ^F to see the next section. ++ ++Section 3: {^F} {^B} ++You now have two basic commands for examining a file, both forwards (^F) and ++backwards (^B). ++ ++Note that these are vi text editing commands: they are not commands for the ++tutorial. Indeed, this tutorial is nothing but a text file which you are now ++editing. Everything you do and learn in this tutorial will be applicable to ++editing text files. ++ ++Therefore, when you are editing a file and are ready to see more of the text, ++entering ^F will get you to the next section of the file. Entering ^B will ++show you the previous section. ++ ++Time for you to do another ^F. ++ ++ ++ ++ ++ ++ ++ ++Section 4: {^F} {^B} {^M} (return key) ++We will adopt the notation of putting commands in curly braces so we can write ++them unambiguously. For example, if you are to type the command sequence ++"control B control F" (as we asked you to do above) it would appear as {^B^F}. ++This allows clear delineation of the command strings from the text. Remember ++that the curly braces are NOT part of the command string you are to type. Do ++NOT type the curly braces. ++ ++Sometimes, the command string in the curly braces will be rather long, and may ++be such that the first couple of characters of the command will erase from ++the screen the string you are trying to read and type. It is suggested that ++you write down the longer commands BEFORE you type them so you won't forget ++them once they disappear. ++ ++Now locate the return key on your keyboard: it is usually marked 'RETURN', ++indicate hitting the return key. In fact, the control-M key sequence is ++exactly the same as if you hit the return key, and vice versa. ++ ++Now type {^F}. ++ ++ ++Section 5: {:q!} {ZZ} {^M} (return key) ++Recognize that this tutorial is nothing more than a text file that you ++are editing. This means that if you do something wrong, it is possible ++for you to destroy the information in this file. Don't worry. If this ++happens, type {ZZ} (two capital Z's) or {:q!^M} to leave the tutorial. ++Restart the tutorial. Once in the tutorial, you can then page forward ++with {^F} until you are back to where you want to be. (There are ++easier ways to do this, some of which will be discussed later, but this ++is the most straightforward.) ++ ++You may want to write these commands down in a convenient place for quick ++reference: {:q!^M} and {ZZ} ++ ++We will assume that you now know to do a {^F} to advance the file ++ ++ ++ ++ ++ ++ ++ ++Section 6: {m} {G} {'} {z} ++Now that you know how to get around in the file via ^F and ^B let's look at ++other ways of examining a text file. Sometimes it is necessary, in the midst ++of editing a file, to examine another part of the file. You are then faced ++with the problem of remembering your place in the file, looking at the other ++text, and then getting back to your original location. Vi has a 'mark' ++command, m. Type {mp}. You have just 'marked' your current location in the ++file and given it the name 'p'. The command string below will do three ++things: position you at the beginning of the file (line 1), then return you to ++the location 'p' that you just marked with the 'm' command, and, since the ++screen will not look exactly the same as it does right now, the 'z' command ++will reposition the screen. (You may want to write the string down before ++typing it: once you type {1G} it will no longer be on the screen.) ++ ++So now type {1G'pz^M} - a one followed by a capital G, followed by the quote ++mark, followed by a lower case 'p', then a lower case 'z', then a return ++(which is the same as a ^M). The {1G} moves you to line 1, i.e. the beginning ++of the file. The {'p} moves you to the location you marked with {mp}. The ++{z^M} command will repaint the screen putting the cursor at the top of the ++screen. (Now {^F}.) ++ ++Section 7: {m} {G} {'} {z} ++Let's look at some variations on those commands. If you wanted to look at ++line 22 in the file and return to this location you could type {mp22G'p}. Do ++so now, observing that {22G} puts your cursor at the beginning of section 2 in ++the middle of the screen. ++ ++Also note that, without the {z^M} command, the line with 'Section 7' on it is ++now in the MIDDLE of the screen, and not at the top. Our cursor is on the ++correct line (where we did the {mp} command) but the line is not where we ++might like it to be on the screen. That is the function of the {z^M} command. ++(Remember, ^M is the same as the 'return' key on your keyboard.) Type {z^M} ++now and observe the effect. ++ ++As you can see, the 'Section 7' line is now at the top of the screen with the ++cursor happily under the capital S. If you would like the cursor line (i.e. ++the line which the cursor is on) in the middle of the screen again, you would ++type {z.}. If you wanted the cursor line to be at the BOTTOM of the screen, ++type {z-}. Try typing {z-z.z^M} and watch what happens. ++ ++{^F} ++ ++Section 8: {z} {m} {'} ++ ++Note that the z command does not change the position of our cursor in the file ++itself, it simply moves the cursor around on the screen by moving the contents ++of the file around on the screen. The cursor stays on the same line of the ++file when using the z command. ++ ++This brings up an important point. There are two questions that the users of ++vi continually need to know the answer to: "Where am I in the file?" and ++"Where am I on the screen?" The cursor on your terminal shows the answer to ++both questions. Some commands will move you around in the file, usually ++changing the location of the cursor on the screen as well. Other commands ++move the cursor around on the screen without changing your location in the ++file. ++ ++Now type {ma}. Your location in the file has been given the name 'a'. If you ++type {'p'a} you will see the previous location we marked in section 7, and ++then will be returned to the current location. (You will want to do a {z^M} ++to repaint the screen afterwards.) Try it. ++{^F} ++ ++Section 9: {m} {''} ++Now we can move about in our file pretty freely. By using the {m} command we ++can give the current cursor position a lower-case-character name, like 'p', ++'a', 'e', 'm', or 'b'. Using the {G} command preceded by a line number we can ++look at any line in the file we like. Using the single quote command {'} ++followed by a character used in an {m} command, we can return to any location ++in the file we have marked. ++ ++However, try {m3}, or {mM}. You should hear a beep, or bell. Only lower-case ++letters are acceptable to the {m} and {'} commands: numbers, upper-case ++letters, and special characters are not acceptable. ++ ++If you type the {'} command with a character that is lower-case alphabetic but ++that has not been used in an {m} command, or for which the 'marked' text has ++been deleted, you will also get a beep. Try {'i}. You should get a beep ++because the command {mi} has never been issued. (Unless you've been ++experimenting.) ++ ++The command {''} attempts to return you to the location at which you last ++modified some part of your file. However, my experience has been that it is ++difficult to predict exactly where you will end up. ++Section 10: {^M} {-} ++Now do {ma}, marking your position at the top of the screen. Now hit {^M} (or ++return) until the cursor is right ... ++* <- here, over/under the asterisk. Now ++type {mb'a'b} and watch the cursor move from the asterisk to the top of the ++screen and back again. ++ ++The {^M} command moves the cursor to the beginning of the next line. Now type ++{^M} until the cursor is right ... ++* <- here. The command to move the cursor to the beginning of the ++previous line is {-}. Practice moving the cursor around on the screen by using ++{^M} and {-}. BE CAREFUL to not move the cursor OFF the screen just yet. If ++you do, type {'az^M}. ++ ++Now we can move to any line within the screen. Practice moving around in the ++file using the {^F}, {^B}, {-}, {^M}, {z}, and {'} commands. When you are ++fairly confident that you can get to where you need to be in the file, and ++position the cursor on the screen where you want it type {'az^M^F} (which, of ++course, moves you back to the beginning of this section, repositions the ++cursor at the top of the screen, and advances you to the next section). ++ ++Section 11: scrolling: {^M} ++The cursor should now be on the S of 'Section 11', and this should be on the ++first line of the screen. If it is not, do {^M} or {-} as appropriate to put ++the cursor on the section line, and type {z^M}. ++ ++Type {mc} to mark your place. ++ ++Now type {^M} until the cursor is on the last line of this screen. Now do one ++more {^M} and observe the result. This is called scrolling. When you ++attempted to move to a line not displayed on the screen, the line at the top of ++the screen was 'scrolled off', and a line at the bottom of the screen was ++'scrolled on'. The top line with 'Section 11' should no longer be visible. ++ ++Now type {'cz^M} to reset the screen and type {^F} for the next section. ++ ++ ++ ++ ++ ++ ++ ++Section 12: {-} {z} ++ ++The {-} command moves the cursor to the previous line in the file. Now type ++{-}, which attempts to move the cursor to the previous line in this file. ++However, that line is not on the screen. The resulting action will depend on ++your terminal. (Do a {^Mz^M} to reposition the file). On intelligent ++terminals (e.g. VT100s, Z19s, Concept 100s), a top line is 'scrolled on' and ++the bottom line is 'scrolled off'. Other terminals, however, may not have ++this 'reverse scrolling' feature. They will simply repaint the screen with ++the cursor line in the middle of the screen. On such terminals it is ++necessary to type {z^M} to get the cursor line back to the top of the screen. ++ ++ ++ ++ ++ ++ ++ ++ ++ ++ ++Section 13: ++Up until this point, the tutorial has always tried to make sure that the first ++line of each screen has on it the section number and a list of the commands ++covered in that section. This will no longer be strictly maintained. If you ++want the section line at the top of the screen, you now know enough commands to ++do it easily: do {^M} or {-} until the cursor is on the section line and ++then {z^M}. Also, from this point on, it may not be the case that a {^F} will ++put you at the beginning of the next section. Therefore, be aware of where you ++are in the file as we look at other commands. You may have to find your way ++back to a particular section without any help from the tutorial. If you do not ++feel comfortable with this, then it is suggested that you practice moving from ++section 1 to section 13, back and forth, using {^M}, {-}, {^F}, and {^B} ++commands for a while. ++ ++Also make liberal use of the mark command {m}: if, for example, you make a ++habit of using {mz} to mark your current location in the file, then you will ++always be able to return to that location with {'z} if the editor does ++something strange and you have no idea where you are or what happened. ++ ++And finally, the proscription against experimentation is hereby lifted: play ++with the editor. Feel free to try out variations on the commands and move ++around in the file. By this time you should be able to recover from any gross ++errors. ++ ++Section 14: {^E} {^Y} {^D} {^U} ++Let us now look at a few other commands for moving around in the file, and ++moving the file around on the screen. Note that the commands we have already ++looked at are sufficient: you really don't need any more commands for looking ++in a file. The following commands are not absolutely necessary. However, ++they can make editing more convenient, and you should take note of their ++existence. But it would be perfectly valid to decide to ignore them on this ++first pass: you can learn them later when you see a need for them, if you ever ++do. ++ ++First, let's clear up some potentially confusing language. In at least one ++place in the official document ('An Introduction to Display Editing with Vi' ++by William Joy, and Mark Horton, September 1980), the expression "to scroll ++down text" means that the cursor is moved down in your file. However, note ++that this may result in the text on the screen moving UP. This use of the ++word 'scroll' refers to the action of the cursor within the file. However, ++another legitimate use of the word refers to the action of the text on the ++screen. That is, if the lines on your screen move up toward the top of the ++screen, this would be 'scrolling the screen up'. If the lines move down ++toward the bottom of the screen, this would be refered to as scrolling down. ++ ++I have tried to maintain the following jargon: 'scrolling' refers to what the ++text does on the screen, not to what the cursor does within the file. For the ++latter I will refer to the cursor 'moving', or to 'moving the cursor'. I ++realize that this is not necessarily consistent with Joy and Horton, but they ++were wrong. ++ ++{^E} scrolls the whole screen up one line, keeping the cursor on the same line, ++if possible. However, if the cursor line is the first line on the screen, then ++the cursor is moved to the next line in the file. Try typing {^E}. ++ ++{^Y} scrolls the screen down one line, keeping the cursor on the same line, if ++possible. However, if the cursor line is the last line on the screen, then the ++cursor is moved to the previous line in the file. Try it. ++ ++{^D} moves the cursor down into the file, scrolling the screen up. ++ ++{^U} moves the cursor up into the file, also scrolling the screen if the ++terminal you are on has the reverse scroll capability. Otherwise the ++screen is repainted. ++ ++Note that {^E} and {^Y} move the cursor on the screen while trying to keep the ++cursor at the same place in the file (if possible: however, the cursor can ++never move off screen), while {^D} and {^U} keep the cursor at the same place ++on the screen while moving the cursor within the file. ++ ++Section 15: {/ .. /^M} ++ ++Another way to position yourself in the file is by giving the editor a string ++to search for. Type the following: {/Here 1/^M} and the cursor should end up ++right ...........................here ^. Now type {/Section 15:/^M} and the ++cursor will end up over/on .....................here ^. Now type {//^M} and ++observe that the cursor is now over the capital S five lines above this line. ++Typing {//^M} several more times will bounce the cursor back and forth between ++the two occurrences of the string. In other words, when you type a string ++between the two slashes, it is searched for. Typing the slashes with nothing ++between them acts as if you had typed the previous string again. ++ ++Observe that the string you type between the two slashes is entered on the ++bottom line of the screen. Now type {/Search for x /^M} except replace the 'x' ++in the string with some other character, say 'b'. The message "Pattern not ++found" should appear on the bottom of the screen. If you hadn't replaced the ++'x', then you would have found the string. Try it. ++ ++Section 16: {? .. ?^M} {n} (search strings: ^ $) ++ ++When you surround the sought-for string with slashes as in {/Search/}, the ++file is searched beginning from your current position in the file. If the ++string is not found by the end of the file, searching is restarted at the ++beginning of the file. However, if you do want the search to find the ++PREVIOUS rather than the NEXT occurrence of the string, surround the string ++with question marks instead of slash marks. ++ ++Below are several occurrences of the same string. ++Here 2 Here 2 Here 2 ++ Here 2 Here 2. ++Observe the effect of the following search commands (try them in the ++sequence shown): ++{/Here 2/^M} {//^M} {??^M} ++{/^Here 2/^M} {//^M} {??^M} ++{/Here 2$/^M} {//^M} {??^M} ++ ++The first command looks for the next occurrence of the string 'Here 2'. ++However the second line of commands looks for an occurrence of 'Here 2' that ++is at the beginning of the line. When the up-arrow is the first character of ++a search string it stands for the beginning of the line. When the dollar-sign ++is the last character of the search string it stands for the end of the line. ++Therefore, the third line of commands searches for the string only when it is ++at the end of the line. Since there is only one place the string begins a ++line, and only one place the string ends the line, subsequent {//^M} and ++{??^M} will find those same strings over and over. ++ ++The {n} command will find the next occurrence of the / or ? search ++string. Try {/Here 2/^M} followed by several {n} and observe the ++effect. Then try {??^M} followed by several {n}. The {n} command ++remembers the direction of the last search. It is just a way to save a ++few keystrokes. ++ ++Section 17: \ and magic-characters in search strings ++ ++Now type {/Here 3$/^M}. You might expect the cursor to end up ++right......^ here. However, you will get "Pattern not found" at the bottom of ++the screen. Remember that the dollar-sign stands for the end of the line. ++Somehow, you must tell vi that you do not want the end of the line, but a ++dollar-sign. In other words, you must take away the special meaning that the ++dollar-sign has for the search mechanism. You do this (for any special ++character, including the up-arrow ^) by putting a back-slash ('\', not '/') in ++front of the character. ++ ++Now try {/Here 3\$/^M} and you should end up nine lines above this one. Try ++{//^M} and note that it returns you to the same place, and not to the first ++line of this paragraph: the back-slash character is not part of the search ++string and will not be found. To find the string in the first line of this ++paragraph, type {/Here 3\\\$/^M}. There are three back-slashes: the first takes ++away the special meaning from the second, and the third takes away the special ++meaning from the dollar-sign. ++ ++Following is a list of the characters that have special meanings in search ++strings. If you wish to find a string containing one of these characters, you ++will have to be precede the character with a backslash. These characters are ++called magic characters because of the fun and games you can have with them ++and they can have with you, if you aren't aware of what they do. ++ ++ ^ - (up-arrow) beginning of a line ++ $ - (dollar-sign) end of a line ++ . - (period) matches any character ++ \ - (backslant) the escape character itself ++ [ - (square bracket) for finding patterns (see section #SEARCH) ++ ] - (square bracket) ditto ++ * - (asterisk) ditto ++ ++Without trying to explain it here, note that {:set nomagic^M} turns off the ++special meanings of all but the ^ up-arrow, $ dollar-sign, and backslash ++characters. ++ ++Section 18: {: (colon commands)} {ZZ} ++ ++In this section we will discuss getting into and out of the editor in more ++detail. If you are editing a file and wish to save the results the command ++sequence {:w^M} writes the current contents of the file out to disk, using the ++file name you used when you invoked the editor. That is, if you are at the ++command level in Unix, and you invoke vi with {vi foo} where foo is the name ++of the file you wish to edit, then foo is the name of the file used by the ++{:w^M} command. ++ ++If you are done, the write and quit commands can be combined into a single ++command {:wq^M}. An even simpler way is the command {ZZ} (two capital Z's). ++ ++If, for some reason, you wish to exit without saving any changes you have made, ++{:q!^M} does the trick. If you have not made any changes, the exclamation ++point is not necessary: {:q^M}. Vi is pretty good about not letting you ++get out without warning you that you haven't saved your file. ++ ++We have mentioned before that you are currently in the vi editor, editing a ++file. If you wish to start the tutorial over from the very beginning, you ++could {ZZ}, and then type {vi.tut beginner} in response to the Unix prompt. ++This will create a fresh copy of this file for you, which might be necessary ++if you accidentally destroyed the copy you were working with. Just do a ++search for the last section you were in: e.g. {/Section 18:/^Mz^M}. ++ ++Section 19: {H} {M} {L} ++ ++Here are a few more commands that will move you around on the screen. Again, ++they are not absolutely necessary, but they can make screen positioning easier: ++ ++{H} - puts the cursor at the top of the screen (the 'home' position) ++ ++{M} - puts the cursor in the middle of the screen ++ ++{L} - puts the cursor at the bottom of the screen. ++ ++Try typing {HML} and watch the cursor. ++ ++Try typing {5HM5L} and note that 5H puts you five lines from the top of the ++screen, and 5L puts you five lines from the bottom of the screen. ++ ++Section 20: {w} {b} {0} {W} {B} {e} {E} {'} {`} ++ ++Up to this point we have concentrated on positioning in the file, and ++positioning on the screen. Now let's look at positioning in a line. Put the ++cursor at the beginning of the following line and type {z^M}: ++ ++This is a test line: your cursor should initially be at its beginning. ++ ++The test line should now be at the top of your screen. Type {w} several times. ++Note that it moves you forward to the beginning of the next word. Now type ++{b} (back to the beginning of the word) several times till you are at the ++beginning of the line. (If you accidentally type too many {b}, type {w} until ++you are on the beginning of the line again.) Type {wwwww} (five w's) and note ++that the cursor is now on the colon in the sentence. The lower-case w command ++moves you forward one word, paying attention to certain characters such as ++colon and period as delimiters and counting them as words themselves. Now ++type {0} (zero, not o 'oh'): this moves you to the beginning of the current ++line. Now type {5w} and notice that this has the effect of repeating {w} five ++times and that you are now back on the colon. Type {0} (zero) again. To ++ignore the delimiters and to move to the beginning of the next word using only ++blanks, tabs and carriage-returns (these are called white-space characters) to ++delimit the words, use the {W} command: upper-case W. {B} takes you back a ++word using white-space characters as word delimiters. ++ ++Note that the commands {wbWB} do not stop at the beginning or end of a line: ++they will continue to the next word on the next line in the direction specified ++(a blank line counts as a word). ++ ++If you are interested in the END of the word, and not the BEGINNING, then use ++the {e} and {E} commands. These commands only move forward and there are no ++corresponding 'reverse search' commands for the end of a word. ++ ++Also, we have been using the {'} command to move the cursor to a position that ++we have previously marked with the {m} command. However, position the cursor ++in the middle of a line (any line, just pick one) and type {mk}, marking that ++position with the letter k. Now type a few returns {^M} and type {'k}. ++Observe that the cursor is now at the beginning of the line that you marked. ++Now try {`k}: note that this is the reverse apostrophe, or back-quote, or grave ++accent, or whatever you want to call it. Also note that it moves you to the ++character that was marked, not just to the line that was marked. ++ ++In addition, the {``} command works just like the {''} command except that you ++are taken to the exact character, not just to the line. (I'm still not ++sure which exact character, just as I'm still not sure which line.) ++ ++Section 21: {l} {k} {j} {h} ++ ++There are several commands to move around on the screen on a character by ++character basis: ++ ++l - moves the cursor one character to the RIGHT ++k - moves the cursor UP one line ++j - moves the cursor DOWN one line ++h - moves the cursor one character to the LEFT ++ ++Section 22: {i} {a} {I} {A} {o} {O} ^[ (escape key) ++ ++For this and following sections you will need to use the ESCAPE key on your ++terminal. It is usually marked ESC. Since the escape key is the same as ++typing {^[} we will use ^[ for the escape key. ++ ++Probably the most often used command in an editor is the insert command. Below ++are two lines of text, the first correct, the second incorrect. Position your ++cursor at the beginning of Line 1 and type {z^M}. ++ ++Line 1: This is an example of the insert command. ++Line 2: This is an of the insert command. ++ ++To make line 2 look like line 1, we are going to insert the characters ++'example ' before the word 'of'. So, now move the cursor so that it is ++positioned on the 'o' of 'of'. (You can do this by typing {^M} to move ++to the beginning of line 2, followed by {6w} or {wwwwww} to position the cursor ++on the word 'of'.) ++ ++Now carefully type the following string and observe the effects: ++ {iexample ^[} (remember: ^[ is the escape key)} ++The {i} begins the insert mode, and 'example ' is inserted into the line: ++be sure to notice the blank in 'example '. The ^[ ends insertion mode, ++and the line is updated to include the new string. Line 1 should look exactly ++like Line 2. ++ ++Move the cursor to the beginning of Line 3 below and type {z^M}: ++ ++Line 3: These lines are examples for the 'a' command. ++Line 4: These line are examples for the ' ++ ++We will change line four to look like line three by using the append command. ++We need to append an 's' to the word 'line'. Position the cursor on the 'e' ++of 'line'. You can do this in several ways, one way is the following: ++First, type {/line /^M}. This puts us on the word 'line' in Line 4 ++(the blank in the search string is important!). Next, type {e}. The 'e' puts ++us at the end of the word. Now, type {as^[ (^[ is the escape character)}. ++The 'a' puts us in insert mode, AFTER the current character. We appended the ++'s', and the escape ^[ ended the insert mode. ++ ++The difference between {i} (insert) and {a} (append) is that {i} begins ++inserting text BEFORE the cursor, and {a} begins inserting AFTER the cursor. ++ ++Now type {Aa' command.^[}. The cursor is moved to the end of the line and the ++string following {A} is inserted into the text. Line 4 should now look like ++line 3. ++ ++Just as {A} moves you to the end of the line to begin inserting, {I} would ++begin inserting at the FRONT of the line. ++ ++To begin the insertion of a line after the cursor line, type {o}. To insert a ++line before the cursor line, type {O}. In other words {o123^[} is equivalent ++to {A^M123^[}, and {O123^[} is equivalent to {I123^M^[}. The text after the ++{o} or {O} is ended with an escape ^[. ++ ++This paragraph contains information that is terminal dependent: you will just ++have to experiment to discover what your terminal does. Once in the insert ++mode, if you make a mistake in the typing, ^H will delete the previous ++character up to the beginning of the current insertion. ^W will delete the ++previous word, and one of ^U, @, or ^X will delete the current line (up to the ++beginning of the current insertion). You will need to experiment with ^U, @, ++and ^X to determine which works for your terminal. ++ ++Section 23: {f} {x} {X} {w} {l} {r} {R} {s} {S} {J} ++ ++Position the cursor at the beginning of line 5 and {z^M}: ++ ++Line 5: The line as it should be. ++Line 6: The line as it shouldn't be. ++ ++To make Line 6 like Line 5, we have to delete the 'n', the apostrophe, and the ++'t'. There are several ways to position ourselves at the 'n'. Choose ++whichever one suits your fancy: ++ ++{/n't/^M} ++{^M7w6l} or {^M7w6 } (note the space) ++{^M3fn} (finds the 3rd 'n' on the line) ++ ++Now {xxx} will delete the three characters, as will {3x}. ++ ++Note that {X} deletes the character just BEFORE the cursor, as opposed ++to the character AT the cursor. ++ ++Position the cursor at line 7 and {z^M}: ++ ++Line 7: The line as it would be. ++Line 8: The line as it could be. ++ ++To change line 8 into line 7 we need to change the 'c' in 'could' into a 'w'. ++The 'r' (replace) command was designed for this. Typing {rc} is the same as ++typing {xic^[} (i.e. delete the 'bad' character and insert the correct ++new character). Therefore, assuming that you have positioned the cursor on the ++'c' of 'could', the easiest way to change 'could' into 'would' is {rw}. ++ ++If you would like to now change the 'would' into 'should', use the substitute ++command, 's': {ssh^[}. The difference between 'r' and 's' is that 'r' ++(replace) replaces the current character with another character, while 's' ++(substitute) substitutes the current character with a string, ended with an ++escape. ++ ++The capital letter version of replace {R} replaces each character by a ++character one at a time until you type an escape, ^[. The 'S' command ++substitutes the whole line. ++ ++Position your cursor at the beginning of line 9 and {z^M}. ++ ++Line 9: Love is a many splendored thing. ++Line 10: Love is a most splendored thing. ++ ++To change line 10 into line 9, position the cursor at the beginning of 'most', ++and type {Rmany^[}. ++ ++You may have noticed that, when inserting text, a new line is formed by typing ++{^M}. When changing, replacing, or substituting text you can make a new line ++by typing {^M}. However, neither {x} nor {X} will remove ^M to make two lines ++into one line. To do this, position the cursor on the first of the two lines ++you wish to make into a single line and type {J} (uppercase J for 'Join'). ++ ++Section 24: {u} {U} ++ ++Finally, before we review, let's look at the undo command. Position ++your cursor on line 11 below and {z^M}. ++ ++Line 11: The quick brown fox jumped over the lazy hound dog. ++Line 12: the qwick black dog dumped over the laxy poune fox. ++ ++Type the following set of commands, and observe carefully the effect of each ++of the commands: ++ ++{/^Line 12:/^M} {ft} {rT} {fw} {ru} {w} {Rbrown fox^[} {w} {rj} ++{fx} {rz} {w} {Rhound dog^[} ++ ++Line 12 now matches line 11. Now type {U} - capital 'U'. And line 12 now ++looks like it did before you typed in the command strings. Now type: ++ ++{ft} {rT} {fw} {ru} {^M} {^M} ++ ++and then type {u}: the cursor jumps back to the line containing the second ++change you made and 'undoes' it. That is, {U} 'undoes' all the changes on the ++line, and {u} 'undoes' only the last change. Type {u} several times and ++observe what happens: {u} can undo a previous {u}! ++ ++Caveat: {U} only works as long as the cursor is still on the line. Move the ++cursor off the line and {U} will have no effect, except to possibly beep at ++you. However, {u} will undo the last change, no matter where it occurred. ++ ++Section 25: review ++ ++At this point, you have all the commands you need in order to make use of vi. ++The remainder of this tutorial will discuss variations on these commands as ++well as introduce new commands that make the job of editing more efficient. ++Here is a brief review of the basic commands we have covered. They are listed ++in the order of increasing complexity and/or decreasing necessity (to say that ++a command is less necessary is not to say that it is less useful!). These ++commands allow you to comfortably edit any text file. There are other ++commands that will make life easier but will require extra time to learn, ++obviously.
