How to run cron job every 30 seconds

You can run cronjobs every 30 seconds using Unix crontab or FastCron service.

If you are using the Cron Jobs feature from your hosting or your server crontab, you can run cronjob every 30 seconds by setting up 2 cronjobs running every minute, the second one with a 30-second delay:

* * * * * /path/to/script.sh
* * * * * sleep 30 && /path/to/script.sh

Now your script.sh will run every 30 seconds.
