So use > if test -z "$PURIFY"; ... Actually, if $PURIFY is empty, the test will still return exit status 0, since "-z" is a lone, non-empty argument. Silent misbehavior is even worse than a shell complaint (you want exit status 1 if $PURIFY is empty). - -- Don't work too hard, make some time for fun as well!
