Fill out the form to get code you can run in your terminal without verifying its security.Great advice. I hope this is supposed to be a joke? Other than that, why not make it a shellscript where you can give it the paramters using arguments?
And last but not least I think just checking the TTL of the DNS record and then sleeping for that amount of time would be more elegant.
sleep $(dig google.com | grep -A1 "ANSWER SECTION" | tail -n1 | awk '{ print $2 }'); echo -ne '\007' # or bark.sh
