Utility to rename in depth in all files?

Question

linux

Good evening!
I'm looking for a utility under ubuntu for renaming all files in the depth where the match of the text inside the files is found.
I know there is such a utility in webstorm, but I don’t want to use such a monster for a small task :)
Thank you!
