[[explainsFeature::Replace text]]
The [[mw:Extension:Replace_Text|Extension:Replace_Text]] provides a special page (at [[Special:ReplaceText]]) to allow administrators to do a global string find-and-replace on all the content pages of a wiki. It's a global search and replace tool that covers all content in the database and multi-media files. It is obviously useful in many circumstances. It features [[regular expressionexpressions]] support and shows a list of candidate matches before actually doing anything making it safer to 'test' a search and replace operation.
