【问题描述】：

以下命令有什么区别？

git 添加。 git add -A git add -u

我尝试执行它们，它们产生了相同的结果。

【问题讨论】：

之前找不到那个重复的。

【参考方案1】：

git help add

   -A, --all, --no-ignore-removal
       Update the index not only where the working tree has a file matching <pathspec> but also where the index already has an
       entry. This adds, modifies, and removes index entries to match the working tree.

       If no <pathspec> is given, the current version of Git defaults to "."; in other words, update all files in the current
       directory and its subdirectories. This default will change in a future version of Git, hence the form without <pathspec>
       should not be used.

   -u, --update
       Update the index just where it already has an entry matching <pathspec>. This removes as well as modifies index entries to
       match the working tree, but adds no new files.

       If no <pathspec> is given, the current version of Git defaults to "."; in other words, update all tracked files in the
       current directory and its subdirectories. This default will change in a future version of Git, hence the form without
       <pathspec> should not be used.

如果没有给出<pathspec>（你的问题就是这种情况），-A 和-u 都暗示了.。 -A 将暂存更改、删除文件和添加文件。 -u 将暂存更改并删除文件，但不添加文件。

Git 2.0和更早的版本Git 1.X没有区别吗？
