mac和windows切换、多人协同开发时文件大小写命名问题，使用git重命名后：

mv oldfolder newfolder
git add newfolder
git remove oldfolder

It performs a file move, adds the new file to the index and removes the old file from it. We can see there’s no commit so we have to add the updates and commit the changes afterwards.

#git mv oldfolder newfolder
git mv -f oldfolder newfolder
git add -u newfolder
git commit -m "changed the foldername whaddup"

如下情况会出现报错：

git mv foldername folderName

If you’re using a case insensitive filesystem, e.g. you’re on a Mac and you didn’t configure it to be case sensitive, you’ll experience an error message like this one:
fatal: renaming ‘foldername’ failed: Invalid argument

解决如下：

git mv foldername tempname && git mv tempname folderName
