What is a Cron Job & Crontab?

A cron job is a time-based task that is set to run at a specific interval. For example, a cron job can be set to run every day at midnight in order to update a database or send out nightly emails. Cron jobs are typically used for maintenance tasks that need to be performed on a regular basis.

To create or edit a cron job, users must first open the crontab file using a text editor. The crontab file contains instructions for the cron daemon, which is the program that actually executes the commands specified in the file. Each line in the crontab file represents a single task or command.

Cron Fields

Every cron job uses five fields. Here is an explanation of what each field does in this cron, which runs “every minute between 3:00 am and 8:00 pm“:
