What is a Cron Job & Crontab?

A cron job is a task that is scheduled to run at a specific time or interval. Cron jobs are typically used for automating system maintenance or administration tasks, such as running backups or sending email reports.

Each user has their own crontab file, and the commands in this file are only executed by that particular user. The file contains instructions for the cron daemon. To edit your crontab file, you can use the crontab command.

Cron Fields

Every cron job uses five fields. Here is an explanation of what each field does in this cron, which runs “every 1 hour at 40 minutes past the hour“:

  • Field 1: (40) indicates that the task will be run at minute 40.
  • Field 2: (*) indicates that the task will be run every hour.

  • Field 4: (*) indicates that the task will be run every month.
