`find . -regex '.*/.*[^.]+ ([1-9])\.[^.]+$'` wil list the dup files.  Pipe that to a text file, modify it, and source it.  

To delete or move a resulting file like, `./IMG_1286 (1).PNG`, you'll need to escate the space and parens before you can delete (`rm`) them.

Example:  `rm ./IMG_1286\ \(1\).PNG`
