I think you are correct about the intent of unpack. However this is a bad way to do it, if that is the intent. There might also be some issue related to UTF-8 filenames? But again this is not the "right way".

I chomped the input lines and added back in a platform specific line ending in the print because in general, I don't store line endings in data structures because I strive for multi-platform code.

Yes, foreach (keys %first_file) {} could be: foreach (sort keys %first_file) {}
