This works on my /bin/sh and my /bin/ksh:
	echo `expr \`expr 5 + 1\` + 3`
In fact so does this:
	echo `expr \`expr \\\`expr 2 + 3\\\` + 1\` + 3`

I didn't try it with tail or assigning it to a variable but it better
work just as well (I'm assuming that you have a 3 line file, personally
I'd use "tail -1" instead).

Anybody know why the same thing fails on csh?
