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 typically used for maintenance tasks, such as backing up data or updating software.

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 “every quarter“:

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

Field 2: (0) indicates that the task will be run at hour 0 (12 am).

Field 3: (1) indicates that the task will be run on day 1 of every month.

Field 4: (*/3) indicates that the task will be run every 3 months.

Field 5: (*) indicates that the task will be run every day of the week.
