group — user group file
Description
The /etc/group file is a text file that defines the groups on the system. There is one entry per line, with the following format:
group_name:password:GID:user_list
The fields are as follows:
- group_name
the name of the group.
- password
the (encrypted) group password. If this field is empty, no password is needed.
- GID
the numeric group ID.
- user_list
a list of the usernames that are members of this group, separated by commas.

Bugs
As the 4.2BSD initgroups(3) man page says: no one seems to keep /etc/group up-to-date.
