grp
— 组数据库
¶
This module provides access to the Unix group database. It is available on all Unix versions.
Group database entries are reported as a tuple-like object, whose attributes correspond to the members of the
group
structure (Attribute field below, see
<pwd.h>
):

含义 |
|---|---|---|
|
0 |
gr_name |
the name of the group |
|
1 |
gr_passwd |
the (encrypted) group password; often empty |
|
2 |
gr_gid |
the numerical group ID |
|
3 |
gr_mem |
all the group member’s user names |
The gid is an integer, name and password are strings, and the member list is a list of strings. (Note that most users are not explicitly listed as members of the group they are in according to the password database. Check both databases to get complete membership information. Also note that a
gr_name
that starts with a
+
or
-
is likely to be a YP/NIS reference and may not be accessible via
getgrnam()
or
getgrgid()
.)
It defines the following items:
