分离的头不会因创建分支而消失。为什么？

Question

不知道为什么，我总是陷入超然的状态。并且仍然无法找到摆脱它的好方法。有一段时间我在想在分离的头中创建分支就足够了，但这无济于事，HEAD 仍然分离：

>git branch
 (HEAD detached at af34e34)
 master

>git branch detachedhead20160610

>git branch
 (HEAD detached at af34e34)
 detachedhead20160610
 master

>git branch detachedhead20160610
Fatal: A branch named 'detachedhead20160610' already exists.

>git branch detachedhead20160610-2

>git branch
 (HEAD detached at af34e34)
 detachedhead20160610
 detachedhead20160610-2
 master

即刚刚添加的新分支没有固化分离头状态。

您的困惑是因为不知道 git branch 命令的作用。来自 documentation:

Note that this will create the new branch, but it will not switch the working tree to it; use "git checkout " to switch to the new branch.

换句话说，当您git branch detachedhead20160610时，您创建了一个名为detachedhead20160610的新分支，但您没有切换到那个分支，因此 Git 仍然报告你处于分离的头部状态。相反，您有两个选择：

git branch detachedhead20160610      # create a new branch
git checkout detachedhead20160610    # switch to that branch

或者您可以通过一个命令完成：

git checkout -b detachedhead20160610 # create and switch to new branch

分离的头不会因创建分支而消失。为什么？

Detached head does not disappear by creating branch. Why?
