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 commonly used to automate system maintenance or administration tasks, such as running backups or sending emails.

Crontab is a file that contains instructions for the cron daemon. The cron daemon is a program that runs in the background and executes tasks at specified times. The crontab file is used to specify which tasks are to be run and when they are to be run.

Cron Fields

Every cron job uses five fields. Here is an explanation of what each field does in this cron, which runs minutely, or “every minute“:

  • Field 1: (*) indicates that the task will be run every minute.
  • Field 2: (*) indicates that the task will be run every hour.
  • Field 3: (*) indicates that the task will be run every day of the month.
  • Field 4: (*) indicates that the task will be run every month.
  • Field 5: (*) indicates that the task will be run every day of the week.


FUN FACT: Cron jobs can be set up to run at specific times, or they can be configured to run periodically (e.g., every hour)..
