Manual:UserOptions.php

Details
Use the userOptions.php script provided with MediaWiki to change the options for existing users (or see how many are differing from your new defaults).

php userOptions.php gadget-HotCat --new 1 --old ''

For example, to change namespaces search user pages:

php userOptions.php --nowarn --quiet searchNs2 --old 0 --new 1

If you just did create new namespaces, the searchNsX fields are not yet defined. Use the following syntax instead:

php userOptions.php --nowarn --quiet searchNs2 --old "" --new 1

For other namespaces, just replace searchNs# with the namespace number like one of those listed on the ns>Special:MyLanguage/Manual:Namespace#Built-in namespaces|Manual:Namespace page.
