Cron jobs run scheduled commands at specific times from your server or control panel. The Cron Jobs tool in cPanel is helpful for setting up automated maintenance and other unmanned server duties to run at specific times.
You need to have a good knowledge of Linux commands before you can use cron jobs. Check your script with your hosting administrator before adding a cron job as you could cause your server or script to not run and or crash.
