ypcat(1)                                                 ypcat(1)



     NAME
          ypcat - list the contents of the named YP map

     SYNOPSIS
          ypcat [-k] [-t] [-d domainname] mname

          ypcat -x

     DESCRIPTION
          ypcat lists the contents of the yellow pages (YP) map speci-
          fied by mname, which may be either a mapname or a map
          ``nickname.''  Since ypcat uses the YP network services, no
          YP server is specified.

          Suppose you want to look at the system password file.  Each
          machine has a file /etc/passwd, containing only a small
          amount of information.  The network-wide password database
          is served by the YP, and holds information in a map named
          passwd.byname, whose abbreviated name is passwd.  Thus, to
          see the system passwords, you type:

             ypcat passwd

          Here is a list of abbreviated mapnames, full mapnames, and
          corresponding system files:

               passwd     pwd.nm  /etc/passwd
               group      grp.nm  /etc/group
               hosts      hst.ad  /etc/hosts
               networks   ntw.ad  /etc/networks
               services   svc.nm  /etc/services
               protocols  ptc.nr  /etc/protocols
               netgroup   netg    /etc/netgroup

             Note:  This implementation uses shorter abbreviated
             names than other implementations due to an 8 character
             filename limitation.


          Refer to ypfiles(4) and ypserv(1M) for an overview of the
          yellow pages.

     FLAG OPTIONS
          The following flag options are interpreted by ypcat:

          -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.)

          -t   Inhibit translation of mname to mapname.  For example,
               ypcat -t passwd will fail because there is no map named

               passwd, whereas ypcat passwd will be translated to yp-
               cat passwd.byname.

          -d   Specify a domain other that the default domain.  The
               default domain is returned by domainname.

          -x   Display the map nickname table. This lists the nick-
               names (mnames) the command knows of, and indicates the
               mapname associated with each nickname.
