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)?

Answer 1

To create a new branch (locally):

• With the commit hash (or part of it)

   git checkout -b new_branch 6e559cb

• or to go back 4 commits from HEAD

  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

For discarding the last three commits , see Lunaryorn's answer below .

---

For moving your current branch HEAD to the specified commit without creating a new branch , see Arpiagar's answer below .

Answer 2

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 your current branch HEAD to move to the specified commit, below is the command:

 git checkout <commit_hash>

It detaches and 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.

You then might want to go back to the latest commit & fix the detached HEAD:

Answer 3

If you want to throw the latest four commits away, use:

git reset --hard HEAD^^^^

Alternatively, you can specify the hash of a commit you want to reset to:

git reset --hard 6e559cb

Answer 4

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

Answer 5

How can I roll back my previous 4 commits locally in a branch?

Which means, you are not creating new branch and going into detached state. New way of doing that is:

git switch --detach revison

Answer 6

With the new git switch command, we can either:

• git switch -c <new-branch> <commit> to create a new branch named <new-branch> starting at <commit>
• git switch --detach <commit> to switch to a commit for inspection and discardable experiments. See DETACHED HEAD for details.
