Eclipse file search regular expression operation

Question

I have strings like catApple, catBoy, catChild, ... catRobIsAGoodBoy, ... catZebraIsAnAnimal as class names in my application.

Now I have to remove the cat prefix from all class names. Using File Search in Eclipse I can search for cat[A-Z] and that gives me all my matched class names (also ensuring that strings like cat) are filtered out). Additionally I have to lowercase the new first character.

Can I use a $ operator in my replace command in some way and achieve this?

E.g. cat[A-Z] gives me catMercedesIsACar and I convert it to mercedesIsACar.

Thanks.

Since Eclipse regex S&R feature does not support \l / \L...\E operators that can be used in the replacement pattern to perform additional lower-casing operation, you can actually use Notepad++ to search and replace in many files.

In Replace in Files in NPP (press Shift + Ctrl + F), use

\bcat([A-Z])

and replace with \l$1. The word boundary \b will match cat only at the beginning of the words. Note that Match case is ON.
