NOME
gpasswd - administer /etc/group and /etc/gshadow
SINOSSI
gpasswd [opzione] gruppo
DESCRIZIONE
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.
Note sulle password di gruppo
Le password di gruppo rappresentano un intrinseco problema di sicurezza
perché più di una persona deve conoscerle. Ciononostante i gruppi sono
uno strumento molto utile per la cooperazione tra vari utenti.
