GROUPDEL(8) System Management Commands GROUPDEL(8)

NOME

groupdel - rimuove un gruppo

SINOSSI

groupdel [options] GROUP

DESCRIZIONE

The groupdel command modifies the system account files, deleting all entries that refer to GROUP. The named group must exist.

OPZIONI

The options which apply to the groupdel command are:

-f, --force

This option forces the removal of the group, even if there's some user having the group as the primary one.

-h, --help

Mostra un messaggio di aiuto ed esce.

-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.

AVVISI/CAVEAT

Non si può rimuovere un gruppo che sia gruppo primario di un utente. Occorre rimuovere l'utente prima di rimuovere il gruppo.

Occorre controllare manualmente tutti i file system per assicurarsi che non rimanga alcun file avente questo ID di gruppo.

CONFIGURAZIONE

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

MAX_MEMBERS_PER_GROUP (number)

Maximum members per group entry. When the maximum is reached, a new group entry (line) is started in /etc/group (with the same name, same password, and same GID).

The default value is 0, meaning that there are no limits in the number of members in a group.

This feature (split group) permits to limit the length of lines in the group file. This is useful to make sure that lines for NIS groups are not larger than 1024 characters.

If you need to enforce such limit, you can use 25.

Note: split groups may not be supported by all tools (even in the Shadow toolsuite). You should not use this variable unless you really need it.

FILE

/etc/group

Informazioni sugli account di gruppo.

/etc/gshadow
