On Debian, administrators should usually use \fBdeluser\fR(8) instead\&. .PP The \fBuserdel\fR command modifies the system account files, deleting all entries that refer to the user name \fILOGIN\fR\&. The named user must exist\&. .SH "OPTIONEN" .PP The options which apply to the \fBuserdel\fR command are: .PP \fB\-f\fR, \fB\-\-force\fR .RS 4 This option forces the removal of the user account, even if the user is still logged in\&. It also forces \fBuserdel\fR to remove the user\*(Aqs 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 \fBUSERGROUPS_ENAB\fR is defined to \fIyes\fR 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\&. .sp \fINote:\fR This option is dangerous and may leave your system in an inconsistent state\&. .RE .PP \fB\-h\fR, \fB\-\-help\fR .RS 4 zeigt die Hilfe an und beendet das Programm .RE .PP \fB\-r\fR, \fB\-\-remove\fR .RS 4 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, m\(:ussen per Hand gesucht und gel\(:oscht werden\&. .sp The mail spool is defined by the \fBMAIL_DIR\fR variable in the login\&.defs file\&. .RE .PP \fB\-R\fR, \fB\-\-root\fR\ \&\fICHROOT_DIR\fR .RS 4 Apply changes in the \fICHROOT_DIR\fR directory and use the configuration files from the \fICHROOT_DIR\fR directory\&. Only absolute paths are supported\&. .RE .PP \fB\-P\fR, \fB\-\-prefix\fR\ \&\fIPREFIX_DIR\fR .RS 4 Apply changes in the \fIPREFIX_DIR\fR directory and use the configuration files from the \fIPREFIX_DIR\fR 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\&. .RE .PP \fB\-Z\fR, \fB\-\-selinux\-user\fR .RS 4 entfernt die Zuordnung von SELinux\-Benutzern aus den Anmeldeinformationen des Benutzers .RE .SH "KONFIGURATION" .PP The following configuration variables in /etc/login\&.defs change the behavior of this tool: .SH "DATEIEN" .PP /etc/group .RS 4 Informationen zu den Gruppenkonten .RE .PP /etc/login\&.defs .RS 4 Konfiguration der Shadow\-Passwort\-Werkzeugsammlung .RE .PP /etc/passwd .RS 4 Informationen zu den Benutzerkonten .RE .PP /etc/shadow .RS 4 verschl\(:usselte Informationen zu den Benutzerkonten .RE .PP /etc/shadow\-maint/userdel\-pre\&.d/*, /etc/shadow\-maint/userdel\-post\&.d/* .RS 4 Run\-part files to execute during user deletion\&. The environment variable \fBACTION\fR will be populated with \fBuserdel\fR and \fBSUBJECT\fR 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\&. .RE .PP /etc/subgid .RS 4 Per user subordinate group IDs\&. .RE .PP /etc/subuid .RS 4 Per user subordinate user IDs\&. .RE .SH "R\(:UCKGABEWERTE" .PP The \fBuserdel\fR command exits with the following values: .PP \fI0\fR .RS 4 success .RE .PP \fI1\fR .RS 4 can\*(Aqt update password file .RE .PP \fI2\fR .RS 4 invalid command syntax .RE .PP \fI6\fR .RS 4 specified user doesn\*(Aqt exist .RE .PP \fI8\fR .RS 4 user currently logged in .RE .PP \fI10\fR .RS 4 can\*(Aqt update group file .RE .PP \fI12\fR .RS 4 can\*(Aqt remove home directory .RE .SH "WARNUNGEN" .PP \fBuserdel\fR 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\*(Aqs password or account and remove the account later\&. The \fB\-f\fR option can force the deletion of this account\&. .PP Sie sollten von Hand alle Systemdateien \(:uberpr\(:ufen, um sicherzustellen, dass keine Dateien vorhanden sind, die dem gel\(:oschten Benutzer geh\(:oren\&. .PP Sie sollten keine NIS\-Attribute auf einem NIS\-Client l\(:oschen\&. Dies muss auf dem NIS\-Server durchgef\(:uhrt werden\&. .PP If \fBUSERGROUPS_ENAB\fR is defined to \fIyes\fR in /etc/login\&.defs, \fBuserdel\fR will delete the group with the same name as the user\&. To avoid inconsistencies in the passwd and group databases, \fBuserdel\fR 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 \fB\-f\fR option can force the deletion of this group\&. .SH "SIEHE AUCH" .PP \fBchfn\fR(1), \fBchsh\fR(1), \fBpasswd\fR(1), \fBlogin.defs\fR(5), \fBgpasswd\fR(8), \fBgroupadd\fR(8), \fBgroupdel\fR(8), \fBgroupmod\fR(8), \fBsubgid\fR(5), \fBsubuid\fR(5), \fBuseradd\fR(8), \fBusermod\fR(8)\&.
