NAME

       revnetgroup - generate reverse netgroup data

SYNOPSIS

       /usr/lib/yp/revnetgroup [-u|-h]

DESCRIPTION

       Revnetgroup processes the standard input in netgroup(5) format into what is called reverse netgroup form.
       That is, where the original file shows netgroup memberships  in  terms  of  which  members  reside  in  a
       particular  group,  the  reverse  netgroup  format specifies what groups are associated with a particular
       member. This information is used to generate the netgroup.byuser and  netgroup.byhosts  NIS  maps.  These
       reverse  netgroup  maps  are used to help speed up netgroup lookups, particularly for the innetgr library
       function.

       The revnetgroup command prints its results  on  the  standard  output.  It  is  usually  called  only  by
       /var/yp/Makefile when rebuilding the NIS netgroup maps.

OPTIONS

       The revnetgroup command supports the following options:

       -u     Generate  netgroup.byuser  output;  only  username  information  in  the original netgroup file is
              processed.

       -h     Generate netgroup.byhost output; only hostname  information  in  the  original  netgroup  file  is
              processed.

       Note at least one of the both flags must be specified.

FILES

       /var/yp/Makefile    The Makefile to build the NIS databases
       /etc/netgroup       the  default  netgroup  database  file. This file is most often found only on the NIS
                           master server
