You can use
find to recursively find files, and
run commands on those files.
It can be a complicated command, so you'll probably want to make sure you're locating the correct files before modifying them and ensure you have appropriate backups beforehand.
Alternatively, most IDEs will have the ability to search and replace across multiple files/dirs recursively - and will probably have an easier to use interface.
