.DS_Store(英文全称 Desktop Services Store)是一种由苹果公司的Mac OS X操作系统所创造的隐藏文件，目的在于存贮目录的自定义属性，例如文件们的图标位置或者是背景色的选择。相当于 Windows 下的 desktop.ini。

删除 .DS_Store

如果你的项目中还没有自动生成的 .DS_Store 文件，那么直接将 .DS_Store 加入到 .gitignore 文件就可以了。如果你的项目中已经存在 .DS_Store 文件，那就需要先从项目中将其删除，再将它加入到 .gitignore。如下：

删除项目中的所有.DS_Store。这会跳过不在项目中的 .DS_Store

1.find . -name .DS_Store -print0 | xargs -0 git rm -f --ignore-unmatch
