gpasswd

NAME

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

ÜBERSICHT

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.

Hinweise zu Gruppenpasswörtern

Gruppenpasswörter beinhalten ein Sicherheitsrisiko, da mehrere Personen das Passwort kennen. Dennoch können sie sinnvoll sein, um die Zusammenarbeit zwischen Benutzern zu erleichtern.

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,...
