4/20    The return value of rsh bears no relation to the return value of the
        command you're trying to execute on a remote system. So how do I get
        that return value?
        \_ e.g. rsh <machine> 'grep -i foo bar; echo $status'
           \_ Or you could use ssh, which does return the exit status of
              the remote command.
           \_ Many thanx.
