DESCRIPTION
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 -A option to define group
administrator(s) and -M option to define members and
has all rights of group administrators and members.
Group administrator can add and delete users using -a
and -d options respectively. Administrators can use
-r option to remove group password. When no password
is set only group members can use
newgrp (1)
to join the group. Option -R disables
access to the group through
newgrp (1)
command.
gpasswd
called by a group administrator with group name only prompts
for the group password. If password is set the members can still
newgrp (1)
without a password, non-members must supply the password.

/etc/group - group information
