SYNOPSIS
       ypwhich [-d domain] [ [-t] -m  [mname] | [-Vn] hostname]

DESCRIPTION
       ypwhich	returns  the  name  of	the  NIS server that supplies the  NIS name services to a NIS client, or which is the master for a map. If
       invoked without arguments, it gives the NIS server for the local machine.  If hostname is specified, that machine is queried  to  find  out
       which NIS master it is using.

       Refer to ypfiles(4) for an overview of the  NIS name services.

OPTIONS
       -d domain       Use domain instead of the default domain.

       -t	       This option inhibits map nickname translation.

       -m mname        Find  the  master  NIS server for a map.  No hostname can be specified with -m. mname can be a mapname, or a nickname for a
		       map. When mname is omitted, produce a list of available maps.

       -x	       Display the map nickname translation table.

       -Vn	       Version of  ypbind, V3 is default.
