Crontab Examples
On Linux, Crontab is a text file with different content than usual. Each Linux user has a folder with that name, whose file contains a list of the scripts and commands that can be executed by that user.
With the commands we can do several actions automatically (schedule tasks), in the background.
If you have enough knowledge to create scripts, it is in the crontab folder where they will be saved. To create this file you will have to execute the command “crontab”.
