Frequently Asked Questions

How do I schedule a cron job?

On Linux/macOS, run "crontab -e" to open the cron editor, then add a line with 5 time fields followed by the command. For example: "0 9 * * 1-5 /path/to/script.sh" runs a script at 9 AM on weekdays. On cloud platforms, use their specific syntax: GitHub Actions uses "schedule" with cron in YAML, AWS CloudWatch uses rate() or cron() expressions, and Kubernetes uses CronJob resources.

Cron vs Windows Task Scheduler?

Cron is the Unix/Linux job scheduler using 5-field expressions (minute, hour, day, month, weekday). Windows Task Scheduler uses a GUI-based approach with triggers and actions. Cron is text-based and ideal for servers, while Task Scheduler provides a visual interface. For Windows, alternatives include schtasks (CLI) and PowerShell scheduled jobs.

What is the maximum cron frequency?

Standard cron supports a minimum interval of 1 minute (* * * * *). For sub-minute scheduling, use alternative approaches: sleep loops in a cron job, systemd timers (Linux) which support seconds, or specialized tools like fcron. Most cloud platforms also have a minimum of 1 minute, though some support rate expressions like "rate(30 seconds)" for higher frequency.
