|
|
# Author : Stuart Winter <mozes@slackware.com>

|
# Based on the original Slackware adduser by Hrvoje Dogan
|
|
# with modifications by Patrick Volkerding

# History #
|
|
###########
|
|
# v1.18 - 2023-11-25
|
|
# * chown: use new format for supplying user:group.
|
|
# v1.17 - 2019-04-01
|
|
# * Re-invoking input requests when human error causes failure. <ttk>
|
|
# qv: https://www.linuxquestions.org/questions/slackware-14/adduser-shell-script-error-4175650984/
|
|
# v1.16 - 2018-07-22
|
|
# * Added input group. <pjv>
|
|
# v1.15 - 2012-09-13
|
|
# * Added scanner group, which may be required by third party drivers.
|
|
# v1.14 - 2012-08-24
|
|
# * Added lp group, which is now required for scanning. <pjv>
|
|
# v1.13 - 13/01/10
|
|
# * Fixed bug that removed underscore characters from UNIX group names.
|
|
# Thanks to mRgOBLIN for the report and Jim Hawkins for the fix. <sw>
|
|
# 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
