Unix cron

Unix cron is a scheduling tool that automatically runs specific tasks or commands on a computer at predetermined times or intervals. Think of it like a digital alarm clock for your computer, capable of executing scripts, backups, or updates without manual intervention. Users define these schedules using a configuration file called a crontab, specifying when and what to run. This automation helps maintain system routines efficiently, ensuring tasks proceed reliably and on time, freeing users from manual execution and reducing the chance of forgotten tasks.
