Of course, the quotes surrounding the {print...} should be double-quotes, not pairs of single-quotes:

    desc=$(head -1 log | awk "{print \$2}") &&

(I didn't notice the problem when originally composing the email since the compose window wasn't using a fixed-width font, and only noticed it later when re-reading it in a mail reader which does use fixed-width. Sorry for any potential confusion.)

At any rate, using `cut` would be a good option since there's plenty of precedent in existing test scripts.
