You can also control this behavior with the `core.whitespace` setting if you don't wish to remove the carriage returns from your line endings. +[[always-modified-files-case]] +Why do I have a file that's always modified?:: + Internally, Git always stores file names as sequences of bytes and doesn't + perform any encoding or case folding. However, Windows and macOS by default + both perform case folding on file names. As a result, it's possible to end up + with multiple files or directories whose names differ only in case. Git can + handle this just fine, but the file system can store only one of these files, + so when Git reads the other file to see its contents, it looks modified. ++ +It's best to remove one of the files such that you only have one file. You can +do this with commands like the following (assuming two files `AFile.txt` and +`afile.txt`) on an otherwise clean working tree: ++ +---- +$ git rm --cached AFile.txt +$ git commit -m 'Remove files conflicting in case' +$ git checkout . +---- ++ +This avoids touching the disk, but removes the additional file. Your project +may prefer to adopt a naming convention, such as all-lowercase names, to avoid +this problem from occurring again; such a convention can be checked using a +`pre-receive` hook or as part of a continuous integration (CI) system. ++ +It is also possible for perpetually modified files to occur on any platform if a +smudge or clean filter is in use on your system but a file was previously +committed without running the smudge or clean filter.
