DELUSER(8)                  System Manager's Manual                 DELUSER(8)

       deluser, delgroup - remove a user or group from the system

       deluser   [options]   [--force]   [--remove-home]  [--remove-all-files]
       [--backup] [--backup-to DIR] user

       deluser --group [options] group
       delgroup [options] [--only-if-empty] group

       deluser [options] user group

       [--quiet] [--system] [--help] [--version] [--conf FILE]

       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  re-
       moved,  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 di-
       rectory, 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.

       --conf FILE
              Use FILE instead of  the  default  files  /etc/deluser.conf  and

              Remove a group. This is the default action if the program is in-
              voked as delgroup.

       --help Display brief instructions.

              Suppress progress messages.

              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.

              Only remove if no members are left.

              Backup  all  files  contained in the userhome and the mailspool-
              file to a file named /$user.tar.bz2 or /$user.tar.gz.

              Place the backup files not in / but in the  directory  specified
              by this parameter. This implicitly sets --backup also.

              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 from the system owned by this user. Note: --re-
              move-home does not have an effect any more. If --backup is spec-
              ified, the files are deleted after having performed the backup.
