What is a Cron Job & Crontab?

A cron job is a time-based task that is typically set up to run automatically at regular intervals. For example, a cron job might be used to send out a daily email report or to back up files every night.

Crontab files are typically stored in the /etc/crontab file, but they can also be stored in individual user’s home directories. To edit your own crontab file, you can use the command “crontab -e”. This will open up the file in your default text editor.

Cron Fields

Every cron job uses five fields. Here is an explanation of what each field does in this cron, which runs “every 8 days at 10:30 pm“:

Field 1: (30) indicates that the task will be run at minute 30.
