NAME¶

gpasswd - administer /etc/group and /etc/gshadow

ÜBERSICHT¶

gpasswd [option] group

BESCHREIBUNG¶

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.

OPTIONEN¶

Except for the -A and -M options, the options cannot be combined.

The options which apply to the gpasswd command are:

-a, --add user

-d, --delete user

-h, --help

-Q, --root CHROOT_DIR

-r, --remove-password

-R, --restrict

-A, --administrators user,...

-M, --members user,...
