NAME
       group - user group file

DESCRIPTION
       /etc/group  is  a  text	file  which  defines the groups on the system.
       There is one entry per line, with the following 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
	      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.
