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.

   Hinweise zu Gruppenpasswörtern
       Gruppenpasswörter bergen ein Sicherheitsrisiko, da mehrere Personen das Passwort kennen. Dennoch sind
       Gruppen ein nützliches Mittel für die Zusammenarbeit zwischen Benutzern.

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
           Add the user to the named group.

       -d, --delete user
           Remove the user from the named group.

       -h, --help
           zeigt die Hilfe an und beendet das Programm.

       -Q, --root CHROOT_DIR
           Apply changes in the CHROOT_DIR directory and use the configuration files from the CHROOT_DIR
           directory. Only absolute paths are supported.

       -r, --remove-password
           Remove the password from the named group. The group password will be empty. Only group members will
           be allowed to use newgrp to join the named group.

       -R, --restrict
           Restrict the access to the named group. The group password is set to "!". Only group members with a
           password will be allowed to use newgrp to join the named group.

       -A, --administrators user,...
           definiert eine Liste von Benutzern als Gruppenverwalter

       -M, --members user,...
           definiert eine Liste von Benutzern als Gruppenmitglieder
