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.
