search for duplicate modules within a site

Public

It's relatively easy to end up with duplicate modules within a site's file structure. In my experience, they can take a couple of forms. First, multiple versions of a module can be installed in different directories; for instance, one under the "profiles" directory and another under the "sites" directory. Another possibility is creating features to export settings and accidentally using a name already in use on the site.

When run from a site's docroot, the snippet below finds all module files, then strips off the paths, counts the unique occurrences of each name, and then returns all the results with more than one occurrence.
