grp

The grp module provides access to the UNIX group database.

getgrgid(gid)

Returns the group database entry for a group ID, gid. The returned object is a group structure with the following attributes:

• gr_name—The group name

• gr_passwd—The group password (if any)

• gr_gid—The integer group ID

• gr_mem—A list of usernames in the group

The returned object also behaves like a 4-tuple (gr_name, gr_passwd, gr_gid, gr_mem). Raises KeyError if the group doesn’t exist.

getgrnam(name)

Same as getgrgid(), but looks up a group by name.

getgrall()

Returns all available group entries as a list of tuples as returned by getgrgid().
