	Almost. If your .cshrc has these few lines up at the top *before*
you have lines that echo anything, you should be alright. I ran into this
problem on Suns, and this fixed it. It just asks the question: "hey! is
this an interactive shell?"

if (! $?prompt) then
	exit (0)
endif

	* another subject, related to rcp *

	I have a problem with rcp/NFS. It involves 3 Suns: island, jamaica,
and ceylon. island and ceylon are servers, and jamaica is my 3/50 mounted
on ceylon. I tried copying a 5 meg tar file island->jamaica, and the file
got corrupted.  (ceylon was pretty loaded at the time)...so, I rlogin'ed
to ceylon and rcp'ed the same file island->ceylon (and ceylon was just as
loaded, if not more so), and everything was fine. My theory is that a
message saying "NFS server ceylon not responding" issued from jamaica
during the first copy in some way interfered with rcp. Any comments?
Oh yes... island is running 1.2 (!), and jamaica and ceylon are running 3.5.
