Automated Tasks: Cron

Cron is a time-based scheduling service in Linux / Unix-like computer operating systems. Cron job are used to schedule commands to be executed periodically.
You can setup commands or scripts, which will repeatedly run at a set time. Cron is one of the most useful tool in Linux or UNIX like operating systems. The cron service (daemon) runs in the background and constantly checks the /etc/crontab file, /etc/cron./* directories. It also checks the /var/spool/cron/ directory.

Configuring Cron Tasks

In the following example, the crontab command shown below will activate the cron tasks automatically every ten minutes:

*/10 * * * * /usr/bin/php /opt/test.php

In the above sample, the */10 * * * * represents when the task should happen. The first figure represents minutes – in this case, on every "ten" minute. The other figures represent, respectively, hour, day, month and day of the week.

* is a wildcard, meaning "every time".
