How to disable DNS zones for every domain in plesk11

We recently upgraded plesk to v11.0.9 at work
We use an external DNS service, so dont need plesk to handle it for us.

it turns out that there isnt a way to disable dns from the plesk panel.
you can go to tools > DNS settings and turn DNS off
but that only applies to new domains.

if you need to turn off dns for all of your existing domains, try this:

assuming that your domains are all in /var/www/vhosts

ls /var/www/vhosts | while read x; do /usr/local/psa/bin/dns --off $x; done

it will itterate through all the domains listed in /var/www/vhosts and will turn their dns off.
