NAME

6       revnetgroup - generate reverse netgroup data
7

SYNOPSIS

9       /usr/lib64/yp/revnetgroup [-u|-h]
10

DESCRIPTION

12       Revnetgroup  processes  the  standard  input in netgroup(5) format into
13       what is called reverse netgroup form. That is, where the original  file
14       shows  netgroup  memberships in terms of which members reside in a par‐
15       ticular group, the reverse netgroup format specifies  what  groups  are
16       associated with a particular member. This information is used to gener‐
17       ate the netgroup.byuser and netgroup.byhosts NIS  maps.  These  reverse
18       netgroup  maps are used to help speed up netgroup lookups, particularly
19       for the innetgr library function.
20
21       The revnetgroup command prints its results on the standard  output.  It
22       is usually called only by /var/yp/Makefile when rebuilding the NIS net‐
23       group maps.
24

27
28       -u     Generate netgroup.byuser output; only  username  information  in
29              the original netgroup file is processed.
30
31       -h     Generate  netgroup.byhost  output;  only hostname information in
32              the original netgroup file is processed.

37       /var/yp/Makefile    The Makefile to build the NIS databases
