Please update the copying your site via command line page

Hi,

At this page: http://drupal.org/upgrade/copying-your-live-site-via-command-line

There is an instruction to do this at the command line:
wget 'http://civicspacelabs.org/home/files/drupalsql' -O drupalsql.sh chmod +x drupalsql.sh

I don't think this is right because when I inspect the file it downloads, it's an HTML page. When I visit the page it looks like a defunct website. In any case, it looks wrong to me. It's not a shell script. Can someone verify that this should be there?

There is another error I think, but I didn't want to correct it because I'm not sure if it's really an error.

Earlier in the page there is a direction to change $db_url to this in the settings.php file:
$db_url = 'mysql://user:pass@localhost/testsite_db';

But earlier it says to name your test database to "test_site_database". Is the above setting correct? or should it be:
$db_url = 'mysql://user:pass@localhost/test_site_database';

Please advise,

madamep
