A cron job is a task that is scheduled to run at a specific time or interval. Cron jobs are commonly used to automate system maintenance or administration tasks, such as running backups or sending emails.

Crontab files are stored in the “/etc/cron*” directories on most Linux systems. Each user has their own crontab file, and there is also a system-wide crontab file that can be used to schedule system tasks.

Field 1: (*) indicates that the task will be run every minute.

Field 2: (1-19) indicates that the task will be run between hours 1 and 19 (1 am to 7 pm).

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