How to Set Up a Cron Job

A cron job runs a command or script automatically on a schedule you define — for example, clearing a cache every hour, sending a daily report, or running a CMS's scheduled tasks. GrabbyHost's cPanel and DirectAdmin hosting both include a cron job manager so you can set these up yourself.

On cPanel

1. Log in to cPanel and open Cron Jobs under the Advanced section.
2. Under "Add New Cron Job," choose how often it should run using the Common Settings dropdown (for example, Once Per Day), or set custom minute/hour/day/month/weekday values if you need a specific schedule.
3. In the Command field, enter the command to run — for a script this is often something like php -q /home/username/public_html/cron.php (adjust the path to match your actual file location).
4. Click Add New Cron Job to save it.

On DirectAdmin

1. Log in to DirectAdmin and open the Cron Jobs section.
2. Add a new cron job, setting the minute/hour/day/month/weekday fields for your schedule.
3. Enter the command to run, then save.

Understanding the Schedule Fields

Cron schedules use five fields, in this order: minute (0–59), hour (0–23), day of month (1–31), month (1–12), and day of week (0–6, where 0 is Sunday). An asterisk (*) means "every value." For example, 0 3 * * * runs once a day at 3:00 AM, and */15 * * * * runs every 15 minutes. Most control panels also offer common presets (hourly, daily, weekly, monthly) so you don't have to build the schedule by hand.

Common Uses

• Running a CMS's built-in scheduled tasks (many platforms recommend a real server cron job instead of relying on page-load-triggered scheduling for reliability).
• Clearing temporary files or caches on a regular interval.
• Triggering a script that sends scheduled emails or reports.
• Running backup or maintenance scripts you've written yourself.

Good to Know

Cron jobs run under your hosting account, so a broken or overly frequent job can use up resources or send unwanted output as email — check the "send output to" or notification email field in your cron job settings if you want to control that. If a scheduled task isn't running as expected, double-check the command path is correct and that the file has the right permissions to execute.
