Cshell
    cmp -s /etc/motd $HOME/.hushlogin
    if ( $status ) tee $HOME/.hushlogin </etc/motd

Real shell
	cmp -s /etc/motd $HOME/.hushlogin || tee $HOME/.hushlogin </etc/motd
This has tickled bugs on some shells, including early Bash, I think,
so you have to use the more ugly:
	if cmp -s /etc/motd $HOME/.hushlogin ; then
	    :
	else
	    tee $HOME/.hushlogin </etc/motd
	fi
