In case anyone finds this, the syntax is:
Quote:/usr/bin/php index.php welcome cron
The first item is the path to php, second is the path to the index.php file in CI (I've CD'd to the root of my site), the third and fourth items are the controller and method.
With a fresh CI install this works for me. Now to figure out how to get it working with Modular Extensions ...
