Slackware 13.0slackware-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.

+# Program: /usr/sbin/adduser
+# Purpose: Interactive front end to /usr/sbin/useradd for Slackware Linux
+# Author : Stuart Winter <mozes@slackware.com>
+#          Based on the original Slackware adduser by Hrvoje Dogan
+#          with modifications by Patrick Volkerding
+# Version: 1.12
+##########################################################################
+# Usage..: adduser [<new_user_name>]
+##########################################################################
+# History #
+###########
+# v1.12 - 21/07/09
+#       * Adjusted the search of /etc/passwd to exclude the NIS inclusion
+#        string.  Thanks to Dominik L. Borkowski.
+# v1.11 - 04/06/09
+#       * Add power and netdev to the suggested group list
+# v1.10 - 24/03/08
+#       * To facilitate use of the automatic mounting features of HAL,
+#         allow the admin to easily add users to the default groups:
+#         audio,cdrom,video,plugdev,floppy.
+#         The default is not to add new users to these groups.
+#         And by the way, this script is "useradd from Slackware" not
+#         "superadduser from Gentoo" ;-)
+# v1.09 - 07/06/04 
+#       * Added standard Slackware script licence to the head of this file.
+# v1.08 - 25/04/04
+#       * Disallow user names that begin with a numeric because useradd 
+#         (from shadow v4.03) does not allow them. <sw>
+# v1.07 - 07/03/03
+#       * When supplying a null string for the uid (meaning 'Choose next available'), 
+#         if there were file names in the range 'a-z' in the pwd then the 
+#         egrep command considered these files rather than the null string. 
+#         The egrep expression is now in quotes.  
+#         Reported & fixed by Vadim O. Ustiansky <sw>
+# 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. <sw>
+# v1.05 - 04/01/03
+#       * Advise & prevent users from creating logins with '.' characters
+#         in the user name. <sw>
+#       * Made pending account creation info look neater <sw>
+# 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. <sw,pjv>
+# v1.03 - 20/05/02
+#       * Support 'broken' (null lines in) /etc/passwd and 
+#         /etc/group files <sw>       
+#       * 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 <sw>
+# v1.02 - 10/04/02
+#       * Fix user-specified UID bug. <pjv>
+# v1.01 - 23/03/02
+#       * Match Slackware indenting style, simplify. <pjv>
+# v1.00 - 22/03/02
+#       * Created
