Cron jobs are time-based schedulers for scheduling, automating tasks, and executing scripts, commands, and programs. They are often used to automate repetitive tasks like system maintenance, backups, log rotation, database updates, and more.
Cron jobs can be scheduled for a specific time, and it will run the execution process in the background without interrupting user interaction. Cron jobs are widely supported on Unix-like systems, including Linux and macOS. It is an efficient way to automate recurring tasks and ensure that important processes are performed as scheduled.
