Crontab: planned actions with Linux


The program we are discussing today is cron, a lightweight Linux daemon that deals with launch command at user defined intervals. 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.
