On macOS sometimes filenames are left with capital letter(s)

[marekkowalczyk]

macOS filesystem is (typically) case-insensitive but case-preserving: it treats Filename.txt and filename.txt as identical.

Consequently, mv -nv "$oname" "$nname" in the san.sh script fails to rename Filename.txt to filename.txt.

A possible solution could be getting rid of the -n flag in mv -nv. But this risks accidentally overwriting files, as file_name.txt and file name.txt are both transformed to file-name.txt, resulting in the loss of one of the files.
