|
||
.SH NOME
|
||
newgrp \- effettua l'accesso a un nuovo gruppo
|
||
.br
|
||
sg \- esegue un comando con un diverso ID di gruppo
|
||
.SH SINTASSI
|
||
\fBnewgrp\fP [\fB\-\fP] [\fIgruppo\fP]
|
||
.br
|

\fBsg\fP [\fB\-\fP] [\fIgruppo\fP [[\fB\-c\fP] \fIcommndo\fP]]
|
||
.SH DESCRIZIONE
|
||
\fBnewgrp\fP permette di cambiare il proprio ID di gruppo durante una sessione
|
||
di login. Se viene specificato il flag \fB\-\fP, l'ambiente dell'utente viene
|
||
reinizializzato come se l'utente stesse effettuando il login, altrimenti
|
||
l'ambiente non viene modificato e la directory corrente non viene cambiata.
|
||
.PP
|
||
\fBnewgrp\fP changes the current real group ID to the named group, or to the
|
||
default group listed in \fI/etc/passwd\fP if no group name is given. \fBnewgrp\fP
|
||
also tries to add the group to the user groupset. If not root, the user will
|
||
be prompted for a password if she do not have a password and the group does,
|
||
or if the user is not listed as a member and the group has a password. The
|
||
user will be denied access if the group password is empty and the user is
|
||
not listed as a member. If compiled with SHADOWPWD (respectively SHADOWGRP)
|
||
defined, the password of the user (respectively, the password and the
|
||
members of the group) will be overwritten by the value defined in
|
||
\fI/etc/shadow\fP (respectively in \fI/etc/gshadow\fP) if an entry exists for this
|
||
user (resp. group).
|
||
.PP
|
||
Il comando \fBsg\fP funziona in maniera analoga a \fBnewgrp\fP, ma accetta un
|
||
comando che viene eseguito con la shell \fB/bin/sh\fP. La maggior parte delle
|
||
shell che permettono l'uso di \fBsg\fP richiede che i comandi composti da pi<70>
|
||
parole siano inclusi tra apici. Un'altra differenza tra \fBnewgrp\fP e \fBsg\fP <20>
|
||
che alcune shell trattano \fBnewgrp\fP in maniera speciale, sostituendo se
|
||
stesse con la shell creata da \fBnewgrp\fP. Questo non accade con \fBsg\fP, per
|
||
cui all'uscita del comando \fBsg\fP si ritorna al precedente ID di gruppo.
|
||
