Calling a CI function periodically

[eluser]shiroin[/eluser]
I wrote some maintenance functions in a controller called 'maintenance'.

I wish to call the CI function periodically (once/day for instance) to make sure parts of my database are in check.

How do I achieve this?

I don't know much about them but I think cron jobs allow you to execute scripts periodically on a server.

can cron jobs execute URLs?

Use wget to request the URI.
