Cron jobs allow you to automate repetitive tasks on the server that
hosts your web site. This is a powerful tool that allows
you to take a hands-free approach to repetitive tasks. For
example, you could add a cron job that automatically copies
a MySQL database to a separate location on your site as
a backup.
There
are two different modes you can use to add a cron job:
Standard
- Provides a range of pre-set options that you can choose.
This is the simplest method and is recommended.
Advanced
(Unix Style) - Provides the regular Unix style
cron options. Recommended for users who are used to this
method of entering cron entries.
Warning:
You need to have a good knowledge of Linux commands
before you can use cron jobs effectively. Check your script
with your hosting administrator before
adding a cron job.
