    ❓ Cron Job FAQ

    What is cron syntax?

    Cron syntax uses 5 fields: minute (0-59), hour (0-23), day (1-31), month (1-12), and weekday (0-7). Use * for "any value", */n for "every n units", and comma-separated values for specific times.

    How do I test if my cron job is working?

    Run the command manually first to ensure it works. Add output redirection (>> /tmp/cron.log 2>&1) to log output. For reliable monitoring, use UptimePro Heartbeat Monitoring to get alerts when jobs fail.

    Why isn't my cron job running?

    Common issues: Wrong file permissions, incorrect path to script/binary, cron daemon not running, syntax errors in cron expression, missing environment variables. Always use absolute paths in cron commands.

    What's the difference between * and */5?

    * means "every unit" (every minute, every hour, etc.). */5 means "every 5th unit" (every 5 minutes, every 5 hours, etc.). Example: */5 in minute field = runs at :00, :05, :10, :15, etc.
