The

\fBgpasswd\fR

/etc/group, and /etc/gshadow\&. Every group can have

.PP
|
|
System administrators can use the
|
|
\fB\-A\fR
|
|
option to define group administrator(s) and the
|
|
\fB\-M\fR
|
|
option to define members\&. They have all rights of group administrators and members\&.
|

.PP
|

|
without a password, and non\-members must supply the password\&.
