NAME¶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_listThe fields are as follows:
- the name of the group.
- the (encrypted) group password. If this field is empty, no password is needed.
- the numeric group ID.
- 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.
