If you're on Unix then look into using cron. Type the following at the
command prompt to get info on cron:

man 5 crontab

Cron tasks can be scheduled at most once per minute. And if you're
using Windows then I believe the equivalent would be task scheduler,
but I've no idea how you would go about using it.
