REVNETGROUP(8) NIS Reference Manual REVNETGROUP(8)NAMErevnetgroup - 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-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.
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.
