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.
