NAME

group − group file

DESCRIPTION

group contains for each group the following information:

group name
encrypted password
numerical group ID
comma-separated list of group members

This is an ASCII file.  The fields are separated by colons; each group is separated from the next by a new-line.  If a group’s password field is null, newgrp(1) will only allow those users in the group list to change their group ID’s to that fo this group. 

This file resides in directory /etc.  Because of the encrypted passwords, it can and does have general read permission and can be used, for example, to map numerical group ID’s to names.
