How to undo after git commit

How to undo after git commit: 1. Use the git reset command; 2. Use the git revert command; 3. Use the git cherry-pick command.

Git is a distributed version control system that allows users to commit changes in the code repository. But sometimes, we may realize that there are some problems after submission and need to undo it. There are different ways to undo a commit in Git. This article will introduce several common methods to undo git. commit.

The first method is to use the git reset command to undo the most recent commit. This method is relatively simple, just use the following command:

gitresetHEAD~

This will undo the most recent commit, but keep the changes to the file. This means you can re-edit and resubmit these changes.

After undoing the submission, you may need to modify the file and then submit it again. At this time, you can use the following command to modify the file:

gitadd.

This will add all modified files to the temporary storage area. Then, use the following command to commit:

gitcommit-cORIG_HEAD

This will create a new commit and copy the original commit's message in the commit message.

The second method is to use the git revert command to undo the commit. Unlike git reset, git revert creates a new commit that undoes the changes of the most recent commit. Use the following command:

gitrevertHEAD

This will create a new commit that will undo the changes of the most recent commit. In the commit message, you can indicate that this commit undoes the previous commit.

Similarly, after revoking a submission, you may need to modify the file and then submit it again. Use the following command to modify the file:

gitadd.

Then use the following command to commit the changes:

git commit -m "Undo the modifications of the previous submission"

The third method is using git cherry-pick command to selectively undo commits. This approach is suitable for situations where you only need to undo a portion of the changes in the commit. First view the commit history through the following command:

gitlog

This will display all commit history. Find the hash of the commit you want to undo.

Then, use the following command to undo the changes in the commit:

gitcherry-pick-n

This will apply the changes to the workspace, but not commit. You can modify the file to suit your requirements and then commit the changes using the following command:

gitcommit-m"撤销特定提交的修改"

In this article, we have introduced three common methods to undo a git commit. Use the git reset command to undo recent commits, use git revert command to undo a commit and create a new one, using git cherry-pick command to selectively undo commits. Depending on your specific needs, choose the method for reversing a commit that works for you. Either way, remember to make the necessary modifications and resubmit the changes after undoing the commit .
