<H2>DESCRIZIONE</H2>
<P>
<DD>The

by modifying the appropriate entry in the group database.
<A NAME="lbAE">&nbsp;</A>

<DL COMPACT><DT id="2"><DD>
The group ID of the given

will be changed to

<P>
The value of
<I>GID</I>
must be a non-negative decimal integer. This value must be unique, unless the
<B>-o</B>
option is used.
<P>
Gli utenti che hanno il gruppo come gruppo primario verranno aggiornati per mantenere tale gruppo come loro gruppo primario.
<P>
Any files that have the old group ID and must continue to belong to
<I>GROUP</I>, must have their group ID changed manually.
<P>
No checks will be performed with regard to the
<B>GID_MIN</B>,
<B>GID_MAX</B>,
<B>SYS_GID_MIN</B>, or
<B>SYS_GID_MAX</B>
from
/etc/login.defs.
</DL>
<P>
<B>-h</B>, <B>--help</B>
<DL COMPACT><DT id="3"><DD>

<DL COMPACT><DT id="4"><DD>
The name of the group will be changed from
<I>GROUP</I>
to
<I>NEW_GROUP</I>
name.
</DL>
<P>
<B>-o</B>, <B>--non-unique</B>
<DL COMPACT><DT id="5"><DD>
When used with the
<B>-g</B>
option, allow to change the group
<I>GID</I>
to a non-unique value.
</DL>
<P>
<B>-p</B>, <B>--password</B>&nbsp;<I>PASSWORD</I>
<DL COMPACT><DT id="6"><DD>
The encrypted password, as returned by
<B><A HREF="/cgi-bin/man/man2html?3+crypt">crypt</A></B>(3).
<P>
<B>Note:</B>
This option is not recommended because the password (or encrypted password) will be visible by users listing the processes.
<P>
Ci si deve accertare che la password rispetti le norme delle password del sistema.
</DL>
<P>
<B>-R</B>, <B>--root</B>&nbsp;<I>CHROOT_DIR</I>
<DL COMPACT><DT id="7"><DD>
Apply changes in the
<I>CHROOT_DIR</I>
directory and use the configuration files from the
<I>CHROOT_DIR</I>
directory.
</DL>
<P>
<B>-P</B>, <B>--prefix</B>&nbsp;<I>PREFIX_DIR</I>
<DL COMPACT><DT id="8"><DD>
Apply changes in the
<I>PREFIX_DIR</I>
directory and use the configuration files from the
<I>PREFIX_DIR</I>
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.
</DL>
<A NAME="lbAF">&nbsp;</A>
<H2>CONFIGURAZIONE</H2>
<P>
The following configuration variables in
/etc/login.defs
change the behavior of this tool:
<P>
<B>MAX_MEMBERS_PER_GROUP</B> (number)
<DL COMPACT><DT id="9"><DD>
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).
<P>
Il valore predefinito &egrave; 0, che non pone nessun limite al numero di membri per gruppo.
<P>
Questa opzione (dividi gruppo) permette di limitare la lunghezza delle righe nel file &laquo;group&raquo;. Questo &egrave; utile per essere certi che le righe per gruppi NIS non eccedano i 1024 caratteri.
<P>
Se si deve impostare questo limite, si pu&ograve; usare 25.
<P>
Nota: la divisione dei gruppi potrebbe non essere supportata da ogni strumento (anche all'interno del pacchetto Shadow). Non si dovrebbe utilizzare questa variabile a meno di esserci forzati.
</DL>
<A NAME="lbAG">&nbsp;</A>
<H2>FILE</H2>
<P>

<DL COMPACT><DT id="10"><DD>
