.SH DESCRIPTION
|
||
|
|
.B gpasswd
|
||
|
|
is used to administer the /etc/group file (and /etc/gshadow
|
||
|
|
file if compiled with SHADOWGRP defined). Every group can
|
||
|
|
have administrators, members and a password. System
|
||
|
|
administrator can use \fB-A\fR option to define group
|
||
|
|
administrator(s) and \fB-M\fR option to define members and
|
||
|
|
has all rights of group administrators and members.
|
||
|
|
.PP
|
||
|
|
Group administrator can add and delete users using \fB-a\fR
|
||
|
|
and \fB-d\fR options respectively. Administrators can use
|
||
|
|
\fB-r\fR option to remove group password. When no password
|
||
|
|
is set only group members can use
|
||
|
|
.BR newgrp (1)
|
||
|
|
to join the group. Option \fB-R\fR disables
|
||
|
|
access to the group through
|
||
|
|
.BR newgrp (1)
|
||
|
|
command.
|
||
|
|
.PP
|
||
|
|
.B gpasswd
|
||
|
|
called by a group administrator with group name only prompts
|
||
|
|
for the group password. If password is set the members can still
|
||
|
|
.BR newgrp (1)
|
||
|
|
without a password, non-members must supply the password.
