Restoring filenames to recovered files using File Number tag

[keanon]

Hello, I'm looking for a way to batch rename a large number of files to img_#### where the #### is the last 4 digits of the File Number EXIF tag.

Does anyone have experience with this and maybe have a script on hand?

Thanks.

Maybe something like this:

exiftool "-filename<img_${filenumber;$_=sprintf('.4d',$_ % 10000)}" DIR
