Return status of 'rsh'

[Patrick R. Brown]

I am trying to set up a shell script to check for mail on a remote
machine.  The script is the following:

	#! /bin/sh
	#
	#	Check mail on CSGrad since I can't get mail here!!!!
	#
	if [ `rsh csgrad mail -e` ]
	then
		echo You have mail on CSGrad.
	else
		echo You do not have mail on CSGrad.
	fi

This looks nice, but it doesn't work.  (I never "have" mail, even when
I do) What can I do (if anything) to get 'rsh' to return the status of
the command being run remotely.  The Ultrix man pages don't have
anything to say on this topic.  If 'rsh' won't do this, are there any
other ideas?

Thanks in advance,
Pat
