NAME

6       gshadow - shadowed group file
7

DESCRIPTION

9       /etc/gshadow contains the shadowed information for group accounts.
10
11       This file must not be readable by regular users if password security is
12       to be maintained.
13
14       Each line of this file contains the following colon-separated fields:
15
16       group name
17           It must be a valid group name, which exist on the system.
18
19       encrypted password
20           Refer to crypt(3) for details on how this string is interpreted.
21
22           If the password field contains some string that is not a valid
23           result of crypt(3), for instance ! or *, users will not be able to
24           use a unix password to access the group (but group members do not
25           need the password).
26
27           The password is used when a user who is not a member of the group
28           wants to gain the permissions of this group (see newgrp(1)).
29
30           This field may be empty, in which case only the group members can
31           gain the group permissions.
32
33           A password field which starts with an exclamation mark means that
34           the password is locked. The remaining characters on the line
35           represent the password field before the password was locked.
36
37           This password supersedes any password specified in /etc/group.
38
39       administrators
40           It must be a comma-separated list of user names.
41
42           Administrators can change the password or the members of the group.
43
44           Administrators also have the same permissions as the members (see
45           below).
46
47       members
48           It must be a comma-separated list of user names.
49
50           Members can access the group without being prompted for a password.
51
52           You should use the same list of users as in /etc/group.
