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 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
    /etc/gshadow - shadow group information
