Usually any machine that can handle actually doing a job will have no problem with the work checking and not doing it the rest of the time... If you are concerned about it, a stat() is pretty cheap compared to starting a program to do it, so you might write a long-running program to monitor for a new file or a timestamp change instead of starting one every few seconds. If you really want a file-event driven interface you might look at dazuko. http://www.dazuko.de/faq.shtml -- Les Mikesell lesmikesell at gmail.com
