我在哪里？ *（不分支） [英] Where am I? * (no branch)

问题描述

我一直熟悉创建，合并和删除分支。我喜欢知道我在哪里，所以我不会将工作投入错误的分支。我使用 git branch -a 查看我拥有哪些分支。我认为asterix * 显示了我目前正在使用哪个分支。这是什么意思，当我得到：

  *（无分支）
硕士
 origin / HEAD 
  

因为当我 $ git checkout mybranch 我期望看到

  * mybranch 
 master 
 origin / HEAD 
  



对于分支名称参数，git checkout手册页确实提到：

/ p>

 <分支> 
  

分支结帐;
$ b

• 如果它引用了一个分支（即，前缀为 refs / heads / ，是一个有效的ref），那么该分支被检出。否则，如果它指向一个有效的提交，那么你的 HEAD 变成分离，并且你不再在任何分支上。

因此，您不必检出分支名称，而必须签出标签名称有效的提交），使你的 一个独立的人 。

I've been getting familiar with creating, merging and deleting branches. I like to know where I am so I don't commit work into the wrong branch. I use git branch -a to see which branches I have. I think the asterix * shows which branch I'm currently on. What does it mean when I get:

* (no branch)
master
origin/HEAD

Because when I $git checkout mybranch I expect to see

* mybranch
master
origin/HEAD

解决方案

The git checkout man page does mention, for the branch name argument:

<branch>

Branch to checkout;

• if it refers to a branch (i.e., a name that, when prepended with "refs/heads/", is a valid ref), then that branch is checked out.
• Otherwise, if it refers to a valid commit, your HEAD becomes "detached" and you are no longer on any branch.

So instead of having checked out a branch name, you must have checked out a tag name (valid commit), making your HEAD a detached one.
