What is a Cron Job & Crontab?
A cron job is a time-based task that is set to run at specific intervals. This can be anything from running a backup script every night to sending out an email notification once a week. Cron jobs are typically used for maintenance or repetitive tasks.
A crontab is a file that contains instructions for the cron daemon. The cron daemon is a program that runs in the background and executes tasks at specified times.
