How Cron Works?

What is Cron?

Cron is a time-based job scheduler for Unix-like operating systems. It allows users to set up scripts or commands to run automatically at specified times, such as daily, weekly, or monthly. Cron is commonly used for tasks like backups, running applications, system maintenance, and data processing.

What is Cron Job?

A cronjob is a specific task or command scheduled to run at regular intervals as defined in the crontab file. Each cronjob includes a cron expression that specifies when the job will run and the command to be executed. Cronjobs are important for automating routine tasks and making sure they run consistently without manual intervention.

What is Crontab?

Crontab, short for "cron table," is a configuration file that defines the schedule for cron jobs. Each line in a crontab file represents a cron job and contains a cron expression followed by the command to be executed. Users can edit their crontab file using the crontab -e command.
