Submitted by str on Mon, 09/04/2006 - 10:48
  1. Create a text file

    vi crons.txt
  2. Write your cron job on the first line, it should read something like this:

    For Drupal:

    0 * * * * lynx http://www.yourdomain.com/cron.php

    or
    For Xaraya:

    0 * * * * lynx http://www.yourdomain.com/?module=scheduler

    Select one, as what you need; and line break is only at the end of the cron job.
