gpasswd - administer /etc/group and /etc/gshadow
大 纲
|
gpasswd [ option ] group |
描 述
The gpasswd command is used to administer /etc/group, and /etc/gshadow. Every group can have administrators, members and a password.
System administrators can use the -A option to define group administrator(s) and the -M option to define members. They have all rights of group administrators and members.
gpasswd called by a group administrator with a group name only prompts for the new password of the group .
If a password is set the members can still use newgrp (1) without a password, and non-members must supply the password.
请 注 意 组 密 码
Group passwords are an inherent security problem since more than one person is permitted to know the password. However, groups are a useful tool for permitting co-operation between different users.
选 项
Except for the -A and -M options, the options cannot be combined.
The options which apply to the gpasswd command are:
-a , --add user
Add the user to the named group .
-d , --delete user
Remove the user from the named group .
-h , --help
