A cron job is a task that is scheduled to run at a specific time or interval. Cron is a Linux utility that allows tasks to be automatically run in the background at regular intervals. These tasks are often called “cron jobs.”

A crontab is a text file containing a list of commands that are executed at specified times. The commands in the crontab are executed by the cron daemon, which runs in the background and checks for new entries every minute.

Cron Fields

Every cron job uses five fields. Here is an explanation of what each field does in this cron, which runs “every 10 days at 9:00 am“:

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