Yes, you are correct. It's merely habit that I use ! -path vs -prune. Tip: The microseconds you win by using prune are insignificant to the minutes you add by ending with a semicolon, rather then a + sign. With a semi-colon, a fork is done for each positive match. With a plus sign matches are bundled till the max command length is met. -- Mel Problem with today's modular software: they start with the modules and never get to the software part. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
