How to find if a web site uses HSTS

I'm totally new to curl and am trying to ascertain if websites use Strict-Transport-Security.

I'm running off advice. I've been told to check against Chrome's preloaded list and to run

curl -D - https://www.example.com | head -n 20

to check for Strict-Transport-Security headers.

But the 'head' command generated an error and was unknown.

Any ideas?

ATM I'm running Win XP, will have a linux distro in a few days.

Thanks.
