Git how to checkout a commit of a branch
提问by user1615666
How can I check out a commit version of a branch in git?
如何检出 中分支的提交版本git？
For example, my branch, Dev, has a commit ad4f43af43e. How can I check out that commit? Not just a single file, but a whole branch.
例如，我的分支Dev，有一个 commit ad4f43af43e。我怎样才能检查那个提交？不仅仅是单个文件，而是整个分支。
I searched online and found: git checkout <commit>, but it didn't specify branch name
我在网上搜索发现：git checkout <commit>，但它没有指定分支名称
回答by smarber
git checkout <hash> # non named commit
git checkout <branch_name> # named commit
The two lines above will place the HEAD pointer on the given commit. You should know that a branch name is a commit, except it can evolve if you a new commit is added when you're on that branch.
上面的两行将 HEAD 指针放在给定的提交上。您应该知道分支名称是一个提交，除非您在该分支上添加了新的提交，否则它可以演变。
If you want to place your branch Devon the commit ad4f43af43eyou can do this
如果你想把你的分支Dev放在提交上，ad4f43af43e你可以这样做
git branch -f Dev ad4f43af43e
Be careful! This is dangerous because you may loose commits
当心！这很危险，因为您可能会丢失提交

If you're looking to branch out from a specific commit of a branch, first be sure you are in the branch,
如果您想从分支的特定提交中分支出来，首先要确保您在该分支中，
git checkout dev
Now I want to checkout a specific commit 123654 from the dev branch to a new branch while keeping the head on main branch.
现在我想从 dev 分支检出一个特定的提交 123654 到一个新分支，同时保持主分支的头部。
git checkout -b new-branch 123654

You can checkoutto the commit-shathen, create a new branch (say, feature) from that commit.
您可以checkout到commit-sha那时，创建一个新的分支（说feature）从提交。
$ git checkout <commit>
$ git checkout -b feature # create a new branch named `feature` from the commit
# if you want to replace the current branch (say 'develop') with new created branch ('feature')
$ git branch -D develop # delete the local 'develop' branch
$ git checkout -b develop # create a new 'develop' branch from 'feature' branch
