HEAD总是指的是“主人”指的是什么（在这种情况下）？(Does HEAD always refer to what “master” refers to (in this context)?)

假设一个在分支“master”上，并且HEAD位于分支的顶端（例如，在提交C ）。 假设然后执行git reset --hard HEAD^3返回提交A 然后HEAD现在指的是A

问题： “master”是否也指A ，还是指向C ？ 换句话说：在这种情况下，HEAD 总是引用分支“master”的作用（即，假设我们的存储库只有一个名为“master”的分支）？

Suppose one is on branch "master" and that HEAD is at the tip of the branch (say, on commit C). Suppose one then executes git reset --hard HEAD^3 back to commit A. Then HEAD now refers to A.

Question: Does "master" also refer to A, or is it still pointing at C? Put differently: in this context, does HEAD always refer to what the branch "master" does (i.e., assuming that our repository has only one branch named "master")?

最满意答案

让我们检查一下，目前的分支是：

$ git branch * master

回购的当前状态：

$ git log --oneline e585b43 C 4bbf8be B 6ae7d39 A fb4949b Initial commit

让我们改变一下吧：

$ git reset --hard HEAD~3 HEAD is now at fb4949b Initial commit

让我们来看看HEAD指出的位置：

$ git log HEAD --oneline fb4949b Initial commit

让我们检查一下主要点：

$ git log master --oneline fb4949b Initial commit

正如你可以看到HEAD和master指向同一个提交

Let's check it, current branch is:

$ git branch * master

current state of the repo:

$ git log --oneline e585b43 C 4bbf8be B 6ae7d39 A fb4949b Initial commit

Let's rebase it:

$ git reset --hard HEAD~3 HEAD is now at fb4949b Initial commit

Let's check where HEAD points:

$ git log HEAD --oneline fb4949b Initial commit

Let's check where master points:

$ git log master --oneline fb4949b Initial commit

As you can see HEAD and master point at the same commit
