I would add one little thing to that query:

SELECT name FROM system WHERE type='module' AND status='1' AND filename NOT LIKE 'module/%';

That way you don't get Drupal's core modules in the list.

I don't think you'd even need a module to do this. You can get a list of currently used modules by doing:

SELECT name FROM system WHERE type='module' AND status='1';

You could likely write a quick script to compare the list returned by that SQL statement to your modules list.

Originally posted to http://drupal.org/node/1017416:

I have a list of 60+ modules that I download, via drush, to each new Drupal site that I build. I then enable whatever modules are needed for the specific site I'm working on as I carry out the build.

This means that once the site is launched, there may be modules that are not being called by Drupal core but that are still enabled and/or installed.

Is there an automated way - a specific module, for example - that will tell me which of the modules that are enabled on a site are being called by Drupal core?

Secondly, is there any performance implication for having lots of modules installed on a site if they are not enabled?

The answer to the second question seems to be "no". And It doesn't seem that such a module does exist - would it be technically possible to write this module for D6?
