How can I access the bookmarks from the command line?

I need to know that to add firefox 3 compatibility to an <a href="http://www.gnomefiles.org/app.php/Avatar_Factory">application</a>.

In previous version I used something like this:
egrep "imdb.com|youtube.com" "$(find ~/.mozilla/firefox/ -name 'bookmarks.html')"

That returns all bookmark for youtube and imdb but it does not work with version 3.
I know that the file now is places.sqlite

Is it possible?

In the precompiled binaries section is a command line tool.

Thanks but I can get it to do what I want.

It tells me that the database is locked:
Error: database is locked
If I close firefox it tells me:
Unable to open database ".mozilla/firefox/adnu2zvf.default/places.sqlite": file is encrypted or is not a database

The windows version seems to work.
