  Backslashing backquotes to nest command evaluation substitution doesn't work
in the C-shell, and the syntax of shell code in the original poster's message
implies that that's what he's using.

  (As an aside, it would help if people would say in their messages what shell
they are using, and not leave us to guess based on their questions.  Sometimes
it's possible to guess, sometimes it isn't.  People who already make sure to
do this can just ignore the last two sentences. :-)
