Much appreciated Vishal, that makes complete sense. I spent enough time testing it with different combinations of backticks, etc. that I'm not at all surprised that something like that slipped through. I'll tweak it a bit (either later tonight, or early tomorrow) & try it again.
Thanks again.

But the real problem is you're using both $() and ``
It is trying to execute the text output of `df -hl | awk '{print
$NF}' | grep -v ^\/dev` and feeding it into another subshell as a
command, which of course it isn't.
