Translations:Manual:CleanupEmptyCategories.php/18/en

This script will clean up the category table by removing entries for empty categories without a description page and adding entries for empty categories with a description page. It will print out progress indicators every batch. The script is perfectly safe to run on large, live wikis, and running it multiple times is harmless. You may want to use the throttling options if it's causing too much load; they will not affect correctness.
