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 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,
                 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.
