How to setup a server cronjob?

[Selena]

I'm a newbie. I'm running RedHatLinux with cPanel.

I know how to setup cronjobs in cPanel for individual accounts (via the account cPanel). But how do I do this for the server itself? I can't seem to locate this in WHM.

I need to run a rm -rf tmp/* command every 30 mins until I can figure out why my /tmp directory is filling up (100% max every hour).

Any help would be greatly appreciated.

Thank you.

You can run "crontab -e" on the server to add/edit the crons.
