说明
gpasswd administers /etc/group and /etc/gshadow files. It is used to add and remove users from groups, set group administrators, and manage group passwords. Group administrators (set with -A) can add or remove members without root privileges, delegating group management to trusted users. Group passwords (rarely used) allow non-members to temporarily join a group using the newgrp command.
