Overview

Group is a placeholder ::Struct for user group database on Unix systems.

The struct contains the following members

name

contains the name of the group as a String.

passwd

contains the encrypted password as a String. An 'x' is returned if password access to the group is not available; an empty string is returned if no password is needed to obtain membership of the group. This is system-dependent.

gid

contains the group’s numeric ID as an integer.

mem

is an Array of Strings containing the short login names of the members of the group.
