NAMN

       userdel - ta bort ett användarkonto och relaterade filer

SYNOPSIS

       userdel [flaggor] INLOGGNINGSNAMN

BESKRIVNING

       userdel is a low level utility for removing users. On Debian,
       administrators should usually use deluser(8) instead.

       The userdel command modifies the system account files, deleting all
       entries that refer to the user name LOGIN. The named user must exist.

FLAGGOR

       Flaggorna som gäller för kommandot userdel är:

       -f, --force
           This option forces the removal of the user account, even if the
           user is still logged in. It also forces userdel to remove the users
           home directory and mail spool, even if another user uses the same
           home directory or if the mail spool is not owned by the specified
           user. If USERGROUPS_ENAB is defined to yes in /etc/login.defs and
           if a group exists with the same name as the deleted user, then this
           group will be removed, even if it is still the primary group of
           another user.

           Notera: Denna flagga är farlig och kan göra att ditt system
           försätts i ett inkonsistent tillstånd.

       -h, --help
           Visa hjälpmeddelande och avsluta.

       -r, --remove
           Files in the users home directory will be removed along with the
           home directory itself and the users mail spool. Files located in
           other file systems will have to be searched for and deleted
           manually.

           The mail spool is defined by the MAIL_DIR variable in the
           login.defs file.

CONFIGURATION

       The following configuration variables in /etc/login.defs change the
       behavior of this tool:

       MAIL_DIR (string)
           The mail spool directory. This is needed to manipulate the mailbox
           when its corresponding user account is modified or deleted. If not
           specified, a compile-time default is used.

       MAIL_FILE (string)
           Defines the location of the users mail spool files relatively to
           their home directory.

       The MAIL_DIR and MAIL_FILE variables are used by useradd, usermod, and
       userdel to create, move, or delete the users mail spool.

       MAX_MEMBERS_PER_GROUP (number)
           Maximum members per group entry. When the maximum is reached, a new
           group entry (line) is started in /etc/group (with the same name,
           same password, and same GID).

           The default value is 0, meaning that there are no limits in the
           number of members in a group.

           This feature (split group) permits to limit the length of lines in
           the group file. This is useful to make sure that lines for NIS
           groups are not larger than 1024 characters.

           If you need to enforce such limit, you can use 25.

           Note: split groups may not be supported by all tools (even in the
           Shadow toolsuite). You should not use this variable unless you
           really need it.

       USERDEL_CMD (string)
           If defined, this command is run when removing a user. It should
           remove any at/cron/print jobs etc. owned by the user to be removed
           (passed as the first argument).

           The return code of the script is not taken into account.

           Here is an example script, which removes the users cron, at and
           print jobs:

               #! /bin/sh

               # Check for the required argument.
               if [ $# != 1 ]; then
                    echo "Usage: $0 username"
                    exit 1
               fi

               # Remove cron jobs.
               crontab -r -u $1

               # Remove at jobs.
               # Note that it will remove any jobs owned by the same UID,
               # even if it was shared by a different username.
               AT_SPOOL_DIR=/var/spool/cron/atjobs
               find $AT_SPOOL_DIR -name "[^.]*" -type f -user $1 -delete \;

               # Remove print jobs.
               lprm $1

               # All done.
               exit 0

       USERGROUPS_ENAB (boolean)
           If set to yes, userdel will remove the users group if it contains
           no more members, and useradd will create by default a group with
           the name of the user.

TÄNK

       userdel will not allow you to remove an account if there are running
       processes which belong to this account. In that case, you may have to
       kill those processes or lock the users password or account and remove
       the account later. The -f option can force the deletion of this
       account.

       You should manually check all file systems to ensure that no files
       remain owned by this user.

       Du får inte ta bort några NIS-attribut på en NIS-klient. Detta måste
       genomföras på NIS-servern.

       If USERGROUPS_ENAB is defined to yes in /etc/login.defs, userdel will
       delete the group with the same name as the user. To avoid
       inconsistencies in the passwd and group databases, userdel will check
       that this group is not used as a primary group for another user, and
       will just warn without deleting the group otherwise. The -f option can
       force the deletion of this group.
