group(5) - Linux man page

Name

group - user group file

Description

/etc/group is an ASCII file which defines the groups to which users belong. There is one entry per line, and each line has the format:
group_name:passwd:GID:user_list

The field descriptions are:

group_name
the name of the group.
password
the (encrypted) group password. If this field is empty, no password is needed.
GID
the numerical group ID.
user_list
all the group member's user names, separated by commas.

Bugs

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