What is Cron job?
Cron is a utility in Linux, also known as a cron job, is a time-based scheduler in Unix-like operating systems(Linux, Mac OS, etc.) as a pure definition. It simply allows you to schedule execution of commands on your Linux system at specific intervals or on a schedule. You can create almost any kind of schedule with the syntax.
1* * * * * /path/to/script.sh 2* * * * * command
Here, The first 5 asterisk signs allow you to control minutes, days, hours, months and days of weeks. The asterisk sign means “Every”. It means that the above given command and script will run every minute, every hour, every day of the week, all the days in a month, and every month!
