There +are several versions (or clones) of <tt class="COMMAND">vi</tt> available, including <tt +class="COMMAND">vi</tt>, <tt class="COMMAND">elvis</tt>, <tt class="COMMAND">vile</tt>, +and <tt class="COMMAND">vim</tt>. One of these is available on just about any version of +Unix, as well as on Linux. All of these versions include the same basic feature set and +commands, so learning one clone should make it easy to learn another. With the variety of +text editors included with Linux distributions and Unix variants these days, many people +no longer use <tt class="COMMAND">vi</tt>. Still, it remains the most universal text +editor across Unix and Unix work-alikes. Mastering <tt class="COMMAND">vi</tt> means you +should never be sitting at a Unix machine and not be comfortable with at least one +powerful text editor.</p> + +<p><tt class="COMMAND">vi</tt> includes a number of powerful features including syntax +highlighting, code formatting, a powerful search-and-replace mechanism, macros, and more. +These features make it especially attractive to programmers, web developers, and the +like. System administrators will appreciate the automation and integration with the shell +that is possible.</p> + +<p>On Slackware Linux, the default version of <tt class="COMMAND">vi</tt> available is +<tt class="COMMAND">elvis</tt>. Other versions - including <tt class="COMMAND">vim</tt> +and <tt class="COMMAND">gvim</tt> - are available if you've installed the proper +packages. <tt class="COMMAND">gvim</tt> is an X Window version of <tt +class="COMMAND">vim</tt> that includes toolbars, detachable menus, and dialog boxes.</p> + +<div class="SECT1"> +<h1 class="SECT1"><a id="VI-STARTING" name="VI-STARTING">16.1 Starting vi</a></h1> + +<p><tt class="COMMAND">vi</tt> can be started from the command line in a variety of ways. +The simplest form is just:</p> + +<table border="0" bgcolor="#E0E0E0" width="100%"> +<tr> +<td> +<pre class="SCREEN"> +<samp class="PROMPT">%</samp> <kbd class="USERINPUT">vi</kbd> +</pre> +</td> +</tr> +</table> + +<div class="FIGURE"><a id="FIG-VI-VIM-SPLITEDIT" name="FIG-VI-VIM-SPLITEDIT"></a> +<p><b>Figure 16-1. A vi session.</b></p> + +<p><img src="vi/vim-splitedit.png" /></p> +</div> + +<p>This will start up <tt class="COMMAND">vi</tt> with an empty buffer. At this point, +you'll see a mostly blank screen. It is now in “command mode”, waiting for +you to do something. For a discussion of the various <tt class="COMMAND">vi</tt> modes, +see the <a href="vi-modes.html">Section 16.2</a>. In order to quit out of <tt +class="COMMAND">vi</tt>, type the following:</p> + +<table border="0" bgcolor="#E0E0E0" width="100%"> +<tr> +<td> +<pre class="SCREEN"> +<kbd class="USERINPUT">:q</kbd> +</pre> +</td> +</tr> +</table> + +<p>Assuming that there have been no changes to the file, this will cause <tt +class="COMMAND">vi</tt> to quit. If there have been changes made, it will warn you that +there have been changes and tell you how to disregard them. Disregarding changes usually +means appending an exclamation point after the “<b class="KEYCAP">q</b>” like +so:</p> + +<table border="0" bgcolor="#E0E0E0" width="100%"> +<tr> +<td> +<pre class="SCREEN"> +<kbd class="USERINPUT">:q!</kbd> +</pre> +</td> +</tr> +</table> + +<p>The exclamation point usually means to force some action. We'll discuss it and other +key combinations in further details later.</p> + +<p>You can also start <tt class="COMMAND">vi</tt> with a pre-existing file. For example, +the file <tt class="FILENAME">/etc/resolv.conf</tt> would be opened like so:</p> + +<table border="0" bgcolor="#E0E0E0" width="100%"> +<tr> +<td> +<pre class="SCREEN"> +<samp class="PROMPT">%</samp> <kbd class="USERINPUT">vi /etc/resolv.conf</kbd> +</pre> +</td> +</tr> +</table> + +<p>Finally, <tt class="COMMAND">vi</tt> can be started on a particular line of a file. +This is especially useful for programmers when an error message includes the line their +program bombed on. For example, you could start up <tt class="COMMAND">vi</tt> on line 47 +of <tt class="FILENAME">/usr/src/linux/init/main.c</tt> like so:</p> + +<table border="0" bgcolor="#E0E0E0" width="100%"> +<tr> +<td> +<pre class="SCREEN"> +<samp class="PROMPT">%</samp> <kbd +class="USERINPUT">vi +47 /usr/src/linux/init/main.c</kbd> +</pre> +</td> +</tr> +</table> + +<p><tt class="COMMAND">vi</tt> will display the given file and will place the cursor at +the specified line. In the case where you specify a line that is after the end of the +file, <tt class="COMMAND">vi</tt> will place the cursor on the last line. This is +especially helpful for programmers, as they can jump straight to the location in the file +that an error occurred, without having to search for it.</p> +</div> +</div> + +<div class="NAVFOOTER"> +<hr align="LEFT" width="100%" /> +<table summary="Footer navigation table" width="100%" border="0" cellpadding="0" +cellspacing="0"> +<tr> +<td width="33%" align="left" valign="top"><a href="archive-files-zip.html" +accesskey="P">Prev</a></td> +<td width="34%" align="center" valign="top"><a href="index.html" +accesskey="H">Home</a></td> +<td width="33%" align="right" valign="top"><a href="vi-modes.html" +accesskey="N">Next</a></td> +</tr> + +<tr> +<td width="33%" align="left" valign="top"><tt class="COMMAND">zip</tt></td> +<td width="34%" align="center" valign="top"> </td> +<td width="33%" align="right" valign="top">Modes</td> +</tr> +</table> +</div> +</body> +</html> + |
