command-line

I'm renaming empty file extensions with this command:

rename *. *.bla

However, I have a folder with hundreds of such subfolders, and this command requires me to manually navigate to each subfolder and run it.

Is there a command that I can run from just one upper level folder that will include all the files in the subfolders?
