I need to get a list of all the files that only differ in case.
I.e., if I have a folder (with sub-folders) with the files:
one.txt ONE.txt two.txt three.txt three.TXT four.txt five/5.txt five/6.txt five/6.Txt
I want some bash magic that will spit out:
one.txt ONE.txt three.txt three.TXT five/6.txt five/6.Txt
