DESCRIPTION
deluser and delgroup remove users and groups from the system according
to command line options and configuration information in
/etc/deluser.conf and /etc/adduser.conf. They are friendlier front
ends to the userdel and groupdel programs, removing the home directory
as option or even all files on the system owned by the user to be
removed, running a custom script, and other features. deluser and del-
group can be run in one of three modes:
Remove a normal user
If called with one non-option argument and without the --group option,
deluser will remove a normal user.
By default, deluser will remove the user without removing the home
directory, the mail spool or any other files on the system owned by
the user. Removing the home directory and mail spool can be achieved
using the --remove-home option.
The --remove-all-files option removes all files on the system owned by
the user. Note that if you activate both options --remove-home will
have no effect because all files including the home directory and mail
spool are already covered by the --remove-all-files option.
If you want to backup all files before deleting them you can activate
the --backup option which will create a file username.tar(.gz|.bz2) in
the directory specified by the --backup-to option (defaulting to the
current working directory). Both the remove and backup options can also
be activated for default in the configuration file /etc/deluser.conf.
See deluser.conf(5) for details.
If you want to remove the root account (uid 0), then use the --force
parameter; this may prevent to remove the root user by accident.
If the file /usr/local/sbin/deluser.local exists, it will be executed
after the user account has been removed in order to do any local
cleanup. The arguments passed to deluser.local are:
username uid gid home-directory
Remove a group
If deluser is called with the --group option, or delgroup is called, a
group will be removed.
Warning: The primary group of an existing user cannot be removed.
If the option --only-if-empty is given, the group won't be removed if
it has any members left.
Remove a user from a specific group
If called with two non-option arguments, deluser will remove a user
from a specific group.
OPTIONS
--conf FILE
Use FILE instead of the default files /etc/deluser.conf and
/etc/adduser.conf
--group
Remove a group. This is the default action if the program is
invoked as delgroup.
--help Display brief instructions.
--quiet
Suppress progress messages.
--system
Only delete if user/group is a system user/group. This avoids
accidentally deleting non-system users/groups. Additionally, if
the user does not exist, no error value is returned. This option
is mainly for use in Debian package maintainer scripts.
--backup
Backup all files contained in the userhome and the mailspool-
file to a file named /$user.tar.bz2 or /$user.tar.gz.
--backup-to
Place the backup files not in / but in the directory specified
by this parameter.
--remove-home
Remove the home directory of the user and its mailspool. If
--backup is specified, the files are deleted after having per-
formed the backup.
--remove-all-files
Remove all files from the system owned by this user. Note:
--remove-home does not have an effect any more. If --backup is
specified, the files are deleted after having performed the
backup.
--version
Display version and copyright information.
