NOM¶
gpasswd - administer /etc/group and /etc/gshadow
SYNOPSIS¶
gpasswd [option] groupe
DESCRIPTION¶
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.
Notes sur les mots de passe de groupe¶
Les mots de passe de groupe représentent naturellement un risque en matière de sécurité, puisque plusieurs personnes ont connaissance du mot de passe. Cependant, les groupes sont utiles pour permettre la coopération entre différents utilisateurs.
OPTIONS¶
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,...
AVERTISSEMENTS¶
This tool only operates on the /etc/group and /etc/gshadow files. Thus you cannot change any NIS or LDAP group. This must be performed on the corresponding server.
CONFIGURATION¶
The following configuration variables in /etc/login.defs change the behavior of this tool:
