I have a wordpress blog with 93 posts on it, in which I want to replace [bash] with <pre> but how do I do it please? I need to go through all the posts changing [bash] to <pre> in each one, but the [bash] doesn't appear in every posting but it is in quite a few, too many to do it by hand with one post after another, I'd rather do it in batches if possible.I believe the posts are stored in a MySQL database, but I can't remember why I believe so!
