Anything sent to stdout from a cron job will be mailed to the owner of the cron job (by default, unless the MAILTO environment variable specifies otherwise). So redirecting to /dev/null is basically a way of saying, "I don't want this mailed to me, just throw it away." Craig -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
