git - `git add .` 和 `git add -u` 有什么区别？

Question

我假设两者的工作方式相同。两者都将每个文件添加到索引中。但我似乎错了。

• git add . 和 git add -u 有什么区别？

Answer 1

它是 git 陷阱之一 mentioned here(Git 2.0 之前)。

git add . 仅添加已存在的内容，不添加已删除的内容(如果已跟踪)。

git add .
git commit
git status
//hey! why didn't it commit my deletes?, Oh yeah, silly me
git add -u .
git commit --amend

git add -A 会处理这两个步骤...

与 Git 2.0, git add -A is default 。

git add <path> is the same as "git add -A <path>" now, so that "git add dir/" will notice paths you removed from the directory and record the removal.
In older versions of Git, "git add <path>" used to ignore removals.

You can say "git add --ignore-removal <path>" to add only added or modified paths in <path>, if you really want to.

警告(git1.8.3 April 2013, for upcoming git2.0)。
我修改了我的答案，说 git add -u . ，而不是 git add -u 。:

git add -u will operate on the entire tree in Git 2.0 for consistency with "git commit -a" and other commands.
Because there will be no mechanism to make "git add -u" behave as "git add -u .", it is important for those who are used to "git add -u" (without pathspec) updating the index only for paths in the current subdirectory to start training their fingers to explicitly say "git add -u ." when they mean it before Git 2.0 comes.

正如我在“e”中提到的
