First, let us understand what a crontab file is. Cron is a software utility that helps us schedule tasks on the Unix based systems. So basically, you’ll be able to periodically run assigned tasks, for example, automated system backups at the end of the day, to auto shutdown or set mode to DND at a particular time and more such features. These "tasks" in cron are usually defined in a file called crontab, which is basically a text file that contains the commands to be executed. Let us now learn how we can write these crontab files in Python using ... Read More
