Cron on Tiger and Tiger Server



Hi!

Is there a way to use the good old cron to launch processes at a predefined time on 10.4 systems? I only seem to get Launchd to launch tasks to be done every X minutes (I have two of them on a Tiger Server machine). When I try a task to start, for example, everyday at 1AM (using the StartCalendarInterval), nothing happens... I'm started to get really "happy" about launchd... it's a wonderful idea, but what's the use if it's so buggy it cannot launch my processes in a reliable way?

For example, yesterday I added a new task to be launched at 1AM every day. I checked with launchctl list and it was there. Today, it's 1:45 AM here, and it did NOT run, and does not show up on launchctl list... what the heck is this?

I paste the plist file here, just to check if I'm doing something wrong...

<?xml version="1.0" encoding="UTF-8"?>
