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:

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.
