Cron
In plain terms
A time-based job scheduler on Unix-like systems.
Going deeper
Cron runs commands automatically at scheduled times defined in crontab entries, automating recurring tasks. It's the classic Unix scheduler.
Under the hood
The crontab syntax sets minute/hour/day patterns; cron daemon executes jobs, missing runs if the system is off.
Examples
Scheduled backups, cleanup jobs, crontab, recurring scripts, automation.
Think of it like...
Like a programmable alarm clock that triggers tasks on a schedule.
