From 5a12e7c134274dba706667107d10d231517d3e05 Mon Sep 17 00:00:00 2001 From: Patrick J Volkerding Date: Wed, 26 Aug 2009 10:00:38 -0500 Subject: Slackware 13.0 Wed Aug 26 10:00:38 CDT 2009 Slackware 13.0 x86_64 is released as stable! Thanks to everyone who helped make this release possible -- see the RELEASE_NOTES for the credits. The ISOs are off to the replicator. This time it will be a 6 CD-ROM 32-bit set and a dual-sided 32-bit/64-bit x86/x86_64 DVD. We're taking pre-orders now at store.slackware.com. Please consider picking up a copy to help support the project. Once again, thanks to the entire Slackware community for all the help testing and fixing things and offering suggestions during this development cycle. As always, have fun and enjoy! -P. --- source/a/shadow/adduser | 437 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 437 insertions(+) create mode 100644 source/a/shadow/adduser (limited to 'source/a/shadow/adduser') diff --git a/source/a/shadow/adduser b/source/a/shadow/adduser new file mode 100644 index 00000000..02385e33 --- /dev/null +++ b/source/a/shadow/adduser @@ -0,0 +1,437 @@ +#!/bin/bash +# +# Copyright 1995 Hrvoje Dogan, Croatia. +# Copyright 2002, 2003, 2004, 2008, 2009 Stuart Winter, Surrey, England, UK. +# Copyright 2004, 2008, 2009 Slackware Linux, Inc., Concord, CA, USA +# All rights reserved. +# +# Redistribution and use of this script, with or without modification, is +# permitted provided that the following conditions are met: +# +# 1.

Ustiansky +# v1.06 - 31/03/03 +# * Ask to chown user.group the home directory if it already exists. +# This helps reduce later confusion when adding users whose home dir +# already exists (mounted partition for example) and is owned +# by a user other than the user to which the directory is being +# assigned as home. Default is not to chown. +# Brought to my attention by mRgOBLIN. +# v1.05 - 04/01/03 +# * Advise & prevent users from creating logins with '.' characters +# in the user name. +# * Made pending account creation info look neater +# v1.04 - 09/06/02 +# * Catered for shadow-4.0.3's 'useradd' binary that no longer +# will let you create a user that has any uppercase chars in it +# This was reported on the userlocal.org forums +# by 'xcp' - thanks. +# v1.03 - 20/05/02 +# * Support 'broken' (null lines in) /etc/passwd and +# /etc/group files +# * For recycling UIDs (default still 'off'), we now look in +# /etc/login.defs for the UID_MIN value and use it +# If not found then default to 1000 +# v1.02 - 10/04/02 +# * Fix user-specified UID bug. +# v1.01 - 23/03/02 +# * Match Slackware indenting style, simplify. +# v1.00 - 22/03/02 +# * Created +####################################################################### + +# Path to files +pfile=/etc/passwd +gfile=/etc/group +sfile=/etc/shells + +# Paths to binaries +useradd=/usr/sbin/useradd +chfn=/usr/bin/chfn +passwd=/usr/bin/passwd +chmod=/bin/chmod + +# Defaults +defhome=/home +defshell=/bin/bash +defchmod=711 # home dir permissions - may be preferable to use 701, however. +defgroup=users +AGID="audio cdrom floppy plugdev video power netdev" # additional groups for desktop users + +# Determine what the minimum UID is (for UID recycling) +# (we ignore it if it's not at the beginning of the line (i.e. commented out with #)) +export recycleUIDMIN="$(grep ^UID_MIN /etc/login.defs | awk '{print $2}' 2>/dev/null)" +# If we couldn't find it, set it to the default of 1000 +if [ -z "$recycleUIDMIN" ]; then + export recycleUIDMIN=1000 # this is the default from Slackware's /etc/login.defs +fi + + +# This setting enables the 'recycling' of older unused UIDs. +# When you userdel a user, it removes it from passwd and shadow but it will +# never get used again unless you specify it expliticly -- useradd (appears to) just +# look at the last line in passwd and increment the uid.
