GROUP(5)                              Linux Programmer's Manual                             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.
