Frequently Asked Questions

What is a cron job?

A cron job is a scheduled task that runs automatically at specified intervals on Unix/Linux systems. The schedule is defined using a cron expression — a string of 5 fields specifying minute, hour, day, month, and weekday.

What does * mean in a cron expression?

An asterisk (*) means 'every'. So * in the minute field means 'every minute', * in the hour field means 'every hour', and so on.

What does */5 mean in a cron expression?

The */n syntax means 'every n units'. So */5 in the minute field means 'every 5 minutes', */2 in the hour field means 'every 2 hours'.

Are cron jobs reliable for critical tasks?

Cron is reliable for most tasks, but does not have built-in retry logic or error alerting. For mission-critical scheduled tasks, consider dedicated job schedulers like Airflow, Temporal, or cloud provider equivalents like AWS EventBridge.
