What is a Cron Job & Crontab?

A cron job is a scheduled task that is typically executed automatically at a predetermined time or interval. Cron jobs are often used to perform routine system maintenance tasks, such as backing up files or databases, deleting temporary files, or sending email notifications.

A crontab is a file that contains a list of commands that are to be executed at specified times. The commands in the crontab are executed by the cron daemon.

Cron Fields

Every cron job uses five fields. Here is an explanation of what each field does in this cron, which runs “every hour between 6:00 am and 6:00 pm“:

Field 1: (0) indicates that the task will be run at minute 0.

Field 2: (6-18) indicates that the task will be run between hours 6 and 18 (6 am to 6 pm).

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: Each user on a system can have their own crontab, and commands in them will be executed as that user..
