In the world of Linux system administration, crontab is a vital tool used for scheduling tasks to run at fixed times or intervals. While it's straightforward to view the cron jobs of the current user with the crontab -l command, what if you need to get an overview of all cron jobs across all users on a system? That's where our handy Bash script comes in.
