What is a Cron Job & Crontab?
A cron job is a time-based task that is set to run at specific intervals. These jobs are usually used for maintenance or automation purposes. For example, a cron job could be set to delete temporary files every week so that they don’t take up space on the server.
A crontab is a table or list of commands that are scheduled to run at specified times. The commands in a crontab file (also called a “cron table”) are normally executed by the cron daemon, which runs in the background and executes these commands automatically.
