USERDEL(8)

NOME
userdel - rimuove l'account di un utente ed i file relativi

SINOSSI

userdel [options] LOGIN

DESCRIZIONE

The userdel command modifies the system account files, deleting all entries that refer to the user name LOGIN. The named user must exist.

OPZIONI

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
    Mostra un messaggio di aiuto ed esce.

-r, --remove
    I file nella home directory dell'utente verranno rimossi insieme alla home directory stessa e alla casella di posta dell'utente. I file collocati in altri file system dovranno essere cercati e rimossi manualmente.

    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
    Rimuove tutti gli utenti SELinux assegnati al login utente.

CONFIGURAZIONE

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

FILE

/etc/group
    Informazioni sugli account di gruppo.

/etc/login.defs
    Configurazione del pacchetto password shadow

/etc/passwd
    Informazioni sugli account utente.

/etc/shadow
    Informazioni sicure sugli account utente.

/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.

VALORI RESTITUITI

The userdel command exits with the following values:

0
    success

1
    can't update password file

2
    invalid command syntax

    specified user doesn't exist

    user currently logged in

AVVISI/CAVEAT

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.

Occorre controllare manualmente tutti i file system per assicurarsi che non rimanga nessun file di proprietà di questo utente.

Non è possibile rimuovere nessun attributo NIS su un client NIS. Questo deve essere fatto sul server 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.
