RMUSER(8)               FreeBSD System Manager's Manual              RMUSER(8)

NAME
     rmuser - remove users from the system

SYNOPSIS
     rmuser [-yv] [-f file] [username ...]

DESCRIPTION
     The rmuser utility removes one or more users submitted on the command
     line or from a file.  In removing a user from the system, this utility:

     1.   Removes the user's crontab(1) entry (if any).

     2.   Removes any at(1) jobs belonging to the user.

     3.   Sends a SIGKILL signal to all processes owned by the user.

     4.   Removes the user from the system's local password file.

     5.   Removes the user's home directory (if it is owned by the user),
          including handling of symbolic links in the path to the actual home
          directory.

     6.   Removes the incoming mail and POP daemon mail files belonging to the
          user from /var/mail.

     7.   Removes all files owned by the user from /tmp, /var/tmp, and
          /var/tmp/vi.recover.

     8.   Removes the username from all groups to which it belongs in
          /etc/group.  (If a group becomes empty and the group name is the
          same as the username, the group is removed; this complements
          adduser(8)'s per-user unique groups.)

     9.   Removes all message queues, shared memory segments and semaphores
          owned by the user.

     The rmuser utility refuses to remove users whose UID is 0 (typically
     root), since certain actions (namely, killing all the user's processes,
     and perhaps removing the user's home directory) would cause damage to a
     running system.  If it is necessary to remove a user whose UID is 0, see
     vipw(8) for information on directly editing the password file.

     If rmuser was not invoked with the -y option, it will show the selected
     user's password file entry and ask for confirmation that the user be
     removed.  It will then ask for confirmation to delete the user's home
     directory.  If the answer is in the affirmative, the home directory and
     any files and subdirectories under it will be deleted only if they are
     owned by the user.  See pw(8) for more details.

     As rmuser operates, it informs the user regarding the current activity.
     If any errors occur, they are posted to standard error and, if it is
     possible for rmuser to continue, it will.

     The options are as follows:

     -f file       The rmuser utility will get a list of users to be removed
                   from file, which will contain one user per line.  Anything
                   following a hash mark (`#'), including the hash mark
                   itself, is considered a comment and will not be processed.
                   If the file is owned by anyone other than a user with UID
                   0, or is writable by anyone other than the owner, rmuser
                   will refuse to continue.

     -y            Implicitly answer ``yes'' to any and all prompts.
                   Currently, this includes prompts on whether to remove the
                   specified user and whether to remove the home directory.
                   This option requires that either the -f option be used, or
                   one or more user names be given as command line arguments.

     -v            Enable verbose mode.  Normally, the output includes one
                   line per removed user; however, with this option rmuser
                   will be much more chatty about the steps taken.

     username      Identifies one or more users to be removed; if not present,
                   rmuser interactively asks for one or more users to be
                   removed.

FILES
     /etc/master.passwd
     /etc/passwd
     /etc/group
     /etc/spwd.db
     /etc/pwd.db

HISTORY
     The rmuser utility appeared in FreeBSD 2.2.

BUGS
     The rmuser utility does not comprehensively search the file system for
     all files owned by the removed user and remove them; to do so on a system
     of any size is prohibitively slow and I/O intensive.  It is also unable
     to remove symbolic links that were created by the user in /tmp or
     /var/tmp, as symbolic links on 4.4BSD file systems do not contain
     information as to who created them.  Also, there may be other files
     created in /var/mail other than /var/mail/username and
     /var/mail/.pop.username that are not owned by the removed user but should
     be removed.

     The rmuser utility has no knowledge of YP/NIS, and it operates only on
     the local password file.
