What is a Cron Job & Crontab?
A cron job is a task that is scheduled to run at a specified time or interval. Cron jobs are typically used to perform system maintenance or administration tasks, such as backing up data or generating reports.
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.
Every cron job uses five fields. Here is an explanation of what each field does in this cron, which runs “every 1 month“:
- 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: (*) indicates that the task will be run every month.
- Field 5: (*) indicates that the task will be run every day of the week.
