group(5)

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_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,
               separated 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.
