group(5) File Formats Manual group(5)
NAME
group - user group file
DESCRIPTION
The /etc/group file is a text file that defines the groups on the sys-
tem. 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, sepa-
rated by commas.
FILES
/etc/group
BUGS
As the 4.2BSD initgroups(3) man page says: no one seems to keep
/etc/group up-to-date.
