Git: set branch to current ref
提问by Patrick B.
Due to the use of submodules in my projects I'm finding myself often on "(no branch)". As I'm also adding code to those submodules I'm committing in there. When I then want to push those submodules I need to be on a branch of course. Hence my question:
由于在我的项目中使用子模块，我发现自己经常处于“（无分支）”状态。因为我也在向那些我在那里提交的子模块添加代码。当我想要推送这些子模块时，我当然需要在一个分支上。因此我的问题是：
Is there a way/shortcut in git (command line) to set a local branch to the current commit/HEAD without the detour of
git（命令行）中是否有一种方法/快捷方式可以将本地分支设置为当前提交/HEAD，而无需绕道
git checkout the_branch
git reset --hard <previous commit-ish>
To be more precise, my real problem with the above "detour" is that I'm temporarily leaving the original HEAD with the checkout-command. That can be avoid with the git branch -fcommand (thanks to CharlesB).
更准确地说，我对上述“绕道”的真正问题是，我暂时使用 checkout-command 离开了原始 HEAD。这可以通过git branch -f命令避免（感谢 CharlesB）。

Checkout the branch with -B: this will reset the branch to HEAD, which is the current ref.
使用以下命令检查分支-B：这会将分支重置为 HEAD，也就是当前的引用。
git checkout -B <branch>
From the docs:
从文档：
If -B is given, is created if it doesn't exist; otherwise, it is reset. This is the transactional equivalent of
$ git branch -f <branch> [<start point>] $ git checkout <branch>that is to say, the branch is not reset/created unless "git checkout" is successful.
如果给出 -B，则如果不存在则创建；否则，它被重置。这是交易等价物
$ git branch -f <branch> [<start point>] $ git checkout <branch>也就是说，除非“git checkout”成功，否则不会重置/创建分支。

git checkout -B the_branch HEAD
This will checkout the_branchat commit HEAD, even if the_branchpointed somewhere else before. It was added in one of the last few git releases, so you might not have it available. An alternate route would be git branch -D the_branch && git checkout -b the_branch
这将the_branch在提交 HEAD时签出，即使the_branch之前指向其他地方。它是在最近几个 git 版本之一中添加的，因此您可能无法使用它。替代路线是git branch -D the_branch && git checkout -b the_branch
