Cron jobs allow you to run scheduled commands or scripts automatically at specific times. They’re commonly used for automating tasks like backups, database cleanups, or running scripts without manual input. The Cron Jobs tool in cPanel makes it easy to set up and manage these automated tasks.
Note: You should have a good understanding of Linux commands before creating cron jobs. Always test your script and, if unsure, consult your hosting administrator before scheduling.

STEP 2: Locate the Advanced section and click on Cron Jobs.
STEP 3: Under Cron Email, ensure the email address listed is valid. If not, enter your preferred email and click Update Email.
This email will receive notifications whenever your cron job runs.
STEP 4: Under Add New Cron Job, choose how often the command should run:
- Use the Common Settings dropdown for frequently used intervals (e.g., every minute, once a day, once a week).
- Or manually set the schedule using the minute, hour, day, month, and weekday fields.
STEP 5: In the Command field, type the command or script path you want to run.
STEP 6: Click Add New Cron Job.
Your cron job is now scheduled and will run at the times you specified.
How to Edit or Delete a Cron Job
