Why is there a `remotes/origin/HEAD -> origin/master` entry in my `git branch -l -a` output?
提问by mistaecko
I don't understand the second line in the output to git branch -l -a: remotes/origin/HEAD -> origin/master.
我不明白输出中的第二行git branch -l -a: remotes/origin/HEAD -> origin/master。
git branch -l -a
* master
remotes/origin/HEAD -> origin/master
remotes/origin/master
Is that a leftover from another operation? Should I clean it up? And how would I do that?
这是另一个手术的剩余物吗？我应该清理它吗？我该怎么做？
Usually I work with git on the cli, but on this local repository I experimented with TortoiseGitto find an easy git workflow for a friend.
通常我在 cli 上使用 git，但在这个本地存储库中，我尝试TortoiseGit为朋友找到一个简单的 git 工作流程。

No, no need to clean up: it is the symbolic branch referenced by your remote repo.
When you clone your repo, you will be by default on the branch referenced by remotes/origin/HEAD.
不，不需要清理：它是远程仓库引用的符号分支。
当您克隆存储库时，默认情况下您将位于remotes/origin/HEAD.

Note: you need to use git branch --list(or git branch), not git branch -l.

You can use git remote set-head origin -dto delete the origin/HEADsymbolic ref, or git remote set-head origin -ato query the remote and automatically set the origin/HEADpointer to the remote's current branch.
您可以使用git remote set-head origin -d删除origin/HEAD符号引用，或git remote set-head origin -a查询远程并自动设置origin/HEAD指向远程当前分支的指针。
The origin/HEADreference is optional. It only acts as a syntactic shortcut: If it exists and points to origin/master, you can use specific simply originwhere you would otherwise specify origin/master.
该origin/HEAD基准是可选的。它仅作为一种语法快捷方式：如果它存在并指向origin/master，您可以简单地使用 specific origin，否则您将指定origin/master。
The git remote(1)man page describes this:
该远程Git（1）手册页描述了这一点：
set-head
Sets or deletes the default branch (i.e. the target of the symbolic-ref refs/remotes//HEAD) for the named remote. Having a default branch for a remote is not required, but allows the name of the remote to be specified in lieu of a specific branch. For example, if the default branch for origin is set to master, then origin may be specified wherever you would normally specify origin/master.
设置头
设置或删除指定远程的默认分支（即符号引用 refs/remotes//HEAD 的目标）。不需要远程的默认分支，但允许指定远程的名称代替特定分支。例如，如果 origin 的默认分支设置为 master，则可以在通常指定 origin/master 的任何地方指定 origin。
