cronometro_300

It is often confused with "crontab", which in reality is nothing but its configuration file, containing the commands to launch and the time intervals. Someone will remember crontab (we used in the tutorial on "time lapse" to take pictures in automatic). In today's article we see an overview of working with cron, accompanied by examples of use, and modify the crontab file.
