       userdel [opcje] LOGIN

OPIS

       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.

OPCJE

       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
           Wyświetlenie komunikatu pomocy i zakończenie działania.

       -r, --remove
           Files in the user's home directory will be removed along with the home directory itself and the
           user's 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.

       -R, --root CHROOT_DIR
           Apply changes in the CHROOT_DIR directory and use the configuration files from the CHROOT_DIR
           directory.

       -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
           Remove any SELinux user mapping for the user's login.

KOD ZAKOŃCZENIA

       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

OSTRZEŻENIA

       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.

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

       You may not remove any NIS attributes on a NIS client. This must be performed on the NIS server.

       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.
