ypcat

ypcat(1)							   User Commands							  ypcat(1)

NAME

       ypcat - print values in a NIS database

SYNOPSIS

       ypcat [-kx] [-d ypdomain] mname

DESCRIPTION

       The ypcat command prints out values in the NIS name service map specified by mname, which may be either a map name or a map nickname. Since
       ypcat uses the NIS network services, no NIS server is specified.

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

OPTIONS

       -k	       Display the keys for those maps in which the values are null or the key is not part of the value.  None of the maps derived
		       from files that have an ASCII version in /etc fall into this class.

       -d ypdomain     Specify a domain other than the default domain.

       -x	       Display map nicknames.
