Cron - Next-generation calendar for professionals and teams

Cron is a time-based job scheduler in Unix-like operating systems that enables users to schedule and automate tasks or commands to run at specific intervals. A "cron job" is a command or script that is scheduled to run automatically at a certain time or interval. The cron daemon reads a configuration file called crontab, which contains a list of scheduled tasks for each user. Cron is commonly used for system maintenance tasks, such as backing up files, cleaning up temporary files, updating software packages, or sending reports. It can also be used to run custom scripts or applications that need to be executed at specific intervals. However, users need to have some knowledge of Unix commands and shell scripting to use cron effectively and avoid conflicts or system overload.
