/etc/gshadow

.PP
|
|
如果没有维护好密码安全，此文件绝对不能让普通用户可读。
|
|
.PP
|
|
此文件的每行包含逗号分隔的如下字段：
|
|
.PP
|
|
\fBgroup name\fR
|
|

|
|
Refer to
|
|
\fBcrypt\fR(3)
|
|
for details on how this string is interpreted\&.
|
|
.sp
|
|
If the password field contains some string that is not a valid result of
|
|
\fBcrypt\fR(3), for instance ! or *, users will not be able to use a unix password to access the group (but group members do not need the password)\&.
|
|
.sp
|
|
The password is used when a user who is not a member of the group wants to gain the permissions of this group (see
|
|
\fBnewgrp\fR(1))\&.
|
|
.sp
|
|
此字段可以为空，此时，只有组成员可以获取组权限。
|

|
|
/etc/group\&.
