git add .、git add -A和git add -u之间的区别

Question

以下命令之间有什么区别？

• 吉特加。
• git添加-A
• git添加-u

我试着执行它们，它们会产生相同的结果。

Answer 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.，则-A和-u都暗示了<pathspec> (在您的问题中是这样的)。
• -A将进行更改、删除文件和添加文件。
• -u将进行更改和删除文件，但不添加文件。
