NAME
       gpasswd - administer the /etc/group file

SYNOPSIS
       gpasswd group
       gpasswd -a user group
       gpasswd -d user group
       gpasswd -R group
       gpasswd -r group
       gpasswd [-A user,...] [-M user,...] group

DESCRIPTION
       gpasswd is used to administer the /etc/group file (and /etc/gshadow file if compiled with SHADOWGRP defined). Every group can have adminis-
       trators, 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 pass-
       word. When no password is set only group members can use newgrp(1) to join the group. Option -R disables access to the group  through  new-
       grp(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 new-
       grp(1) without a password, non-members must supply the password.

FILES

       /etc/gshadow - shadow group information
