USERDEL(8)

NOM
userdel - supprimer un compte utilisateur et les fichiers associés

SYNOPSIS

userdel [options] LOGIN

DESCRIPTION

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.

OPTIONS

The options which apply to the userdel command are:

-f, --force
    This option forces the removal of the user account and any other requested actions, skipping any safety checks.

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

-h, --help
    Afficher un message d'aide et quitter.

-r, --remove
    Les fichiers présents dans le répertoire personnel de l'utilisateur seront supprimés en même temps que le répertoire lui-même, ainsi que le répertoire d'attente des courriels. Vous devrez rechercher et éliminer vous-même les fichiers situés dans d'autres systèmes de fichiers.

    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
    Élimine toute association avec tout utilisateur SELinux pour la connexion de l'utilisateur.

CONFIGURATION

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

FICHIERS

/etc/group
    Informations sur les groupes.

/etc/login.defs
    Configuration de la suite des mots de passe cachés « shadow password ».

/etc/passwd
    Informations sur les comptes des utilisateurs.

/etc/shadow
    Informations sécurisées sur les comptes utilisateurs.

/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
    IDs des groupes subalternes d'un utilisateur.

/etc/subuid
    IDs de utilisateurs subalternes d'un utilisateur.

VALEURS DE RETOUR

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

AVERTISSEMENTS

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.

Vous devez vérifier vous-même qu'aucun fichier possédé par l'utilisateur ne subsiste sur tous les systèmes de fichiers.

Vous ne pouvez supprimer aucun attribut NIS d'un client NIS. Cela doit être effectué sur le serveur NIS.

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.
