How can I roll back my previous 4 commits locally in a branch? In other words, how can I create a branch without my latest 4 commits (assume I have the SHA of that commit from git log)?
如何在分支中本地回滚我之前的 4 次提交？换句话说，如何在没有最近 4 次提交的情况下创建分支（假设我从 git log 获得了该提交的 SHA）？
回答by Artefacto
To create a new branch (locally):
创建一个新分支（本地）：
With the commit hash (or part of it)
git checkout -b new_branch 6e559cbor to go back 4 commits from HEAD
git checkout -b new_branch HEAD~4
使用提交哈希（或其中的一部分）
git checkout -b new_branch 6e559cb或者从 HEAD 返回 4 个提交
git checkout -b new_branch HEAD~4
Once your new branch is created (locally), you might want to replicate this change on a remote of the same name: How can I push my changes to a remote branch
创建新分支（本地）后，您可能希望在同名远程复制此更改：How can I push my changes to a remote branch
For discarding the last three commits, see Lunaryorn's answer below.
要丢弃最后三个提交，请参阅下面的 Lunaryorn 的回答。
For moving your current branch HEAD to the specified commit without creating a new branch, see Arpiagar's answer below.
要在不创建新分支的情况下将当前分支 HEAD 移动到指定的提交，请参阅下面的 Arpiagar 答案。

All the above commands create a new branch and with the latest commit being the one specified in the command, but just in case you want to your current branch HEAD to move to the specified commit, below is the command
以上所有命令都创建了一个新分支，并且最新的提交是命令中指定的那个，但以防万一您希望当前分支 HEAD 移动到指定的提交，下面是命令
git checkout <commit_hash>
It detachesand point the HEAD to specified commit and saves from creating a new branch when the user just wants to view the branch state till that particular commit.
当用户只想查看分支状态直到该特定提交时，它会分离并将 HEAD 指向指定的提交并避免创建新分支。
You then might want to go back to the latest commit & fix the detached HEAD:
然后你可能想回到最新的提交并修复分离的 HEAD：
回答by lunaryorn
If you want to throw the latest four commits away, use:
如果您想丢弃最新的四次提交，请使用：
git reset --hard HEAD^^^^
Alternatively, you can specify the hash of a commit you want to reset to:
或者，您可以指定要重置为的提交的哈希值：
git reset --hard 6e559cb
回答by KingCrunch
Just checkout the commit you wants your new branch start from and create a new branch
只需签出您希望新分支开始的提交并创建一个新分支
git checkout -b newbranch 6e559cb95
