“Crontab” refers to the file used to control the cron service, as well as a command used to edit this file and submit it to the crond daemon for execution. In Unix and Unix-like operating systems, cron is a time-based job scheduler that allows users to schedule commands, scripts, or software to run automatically at specified dates, times, or intervals. These scheduled jobs are known as cron jobs.
The crontab files contain a list of jobs and instructions for the cron daemon. Users can have their own individual crontab files, and there’s often a system-wide crontab file that only system administrators can edit. Each line in a crontab file represents a job and specifies when and how often a particular command or script should be executed.
