       userdel [Optionen] ANMELDENAME

BESCHREIBUNG

       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.

OPTIONEN

       The options which apply to the userdel command are:

       -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 user's 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.

           Note: This option is dangerous and may leave your system in an inconsistent state.

       -h, --help
           zeigt die Hilfe an und beendet das Programm

       -r, --remove
           Die Dateien im Home-Verzeichnis des Benutzers werden zusammen mit dem Home-Verzeichnis
           und dem Mailspool entfernt. Dateien, die sich nicht unterhalb des Home-Verzeichnisses
           befinden, müssen per Hand gesucht und gelöscht werden.

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

       -R, --root CHROOT_DIR
           Apply changes in the CHROOT_DIR directory and use the configuration files from the
           CHROOT_DIR directory. Only absolute paths are supported.

       -P, --prefix PREFIX_DIR
           Apply changes in the PREFIX_DIR directory and use the configuration files from the
           PREFIX_DIR directory. This option does not chroot and is intended for preparing a
           cross-compilation target. Some limitations: NIS and LDAP users/groups are not
           verified. PAM authentication is using the host files. No SELINUX support.

       -Z, --selinux-user
           entfernt die Zuordnung von SELinux-Benutzern aus den Anmeldeinformationen des
           Benutzers

KONFIGURATION

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

DATEIEN

       /etc/group
           Informationen zu den Gruppenkonten

       /etc/login.defs
           Konfiguration der Shadow-Passwort-Werkzeugsammlung

       /etc/passwd
           Informationen zu den Benutzerkonten

       /etc/shadow
           verschlüsselte Informationen zu den Benutzerkonten

       /etc/shadow-maint/userdel-pre.d/*, /etc/shadow-maint/userdel-post.d/*
           Run-part files to execute during user deletion. The environment variable ACTION will
           be populated with userdel and SUBJECT with the username. userdel-pre.d will be
           executed prior to any user deletion. userdel-post.d will execute after user deletion.
           If a script exits non-zero then execution will terminate.

       /etc/subgid
           Per user subordinate group IDs.

       /etc/subuid
           Per user subordinate user IDs.

RÜCKGABEWERTE

       The userdel command exits with the following values:

       0
           success

       1
           can't update password file

       2
           invalid command syntax

       6
           specified user doesn't exist

       8
           user currently logged in

       10
           can't update group file

       12
           can't remove home directory

WARNUNGEN

       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
       user's password or account and remove the account later. The -f option can force the
       deletion of this account.

       Sie sollten von Hand alle Systemdateien überprüfen, um sicherzustellen, dass keine Dateien
       vorhanden sind, die dem gelöschten Benutzer gehören.

       Sie sollten keine NIS-Attribute auf einem NIS-Client löschen. Dies muss auf dem NIS-Server
       durchgeführt werden.

       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.
