How to create a cron job

Forgetting to perform certain tasks is really frustrating for website managers. With a Cron Job, you can set up scheduled tasks for your server.

In this tutorial, I’ll explain what a Cron Job is and how it can help you streamline your work.

What is a Cron Job

A Cron Job is simply a scheduled action that the server performs on a regular basis.

Performing the same task over and over again can sometimes be quite a chore and tedious. Scheduling an action allows users to automate tasks on hosting.

Be careful when using this tool because inappropriate use may adversely affect your server’s performance.

How a Cron Job can be useful

Performing scheduled actions is useful to avoid performing tasks manually, saving time and avoiding tedious and repetitive tasks.

Listed below are just a few of the possible scenarios for using a Cron Job.

  • Antivirus system scan
  • User Account Management
  • Sending scheduled emails
  • Maintenance tasks, such as creating automated backups, checking database integrity, or cleaning the disk of temporary files.

In order to create a new Cron Job you will first need to login to cPanel.
