Reverting Git Commits: A Powerful Technique

Introduction

Git is a powerful tool that allows developers to track changes to their codebase. One of the useful features of Git is the ability to rewind commits. This can be helpful when you need to undo changes or revert to a previous version of your code.

Rewind Commits

As a developer, you have been working on a project and have made several commits. However, you realize that the last few commits contain errors and you need to go back to a previous version of your code. You need to use Git to rewind your commits and get back to the previous version of your code.

To complete this lab, you will use the Git repository git-playground from your GitHub account, which comes from a fork of https://github.com/labex-labs/git-playground.git. Follow these steps:

1. Clone the repository to your local machine:

git clone https://github.com/your-username/git-playground.git
cd git-playground

2. Create a new branch called rewind-commits:

git checkout -b rewind-commits

3. View the commit history of the repository and realize that the last commit contain errors and you need to go back to the previous version of your code:

git log

4. Use Git to rewind your commits by 1:

git reset HEAD~1 --hard

5. Verify that you have successfully rewound your commits:

git log

6. Push your changes to the rewind-commits branch:

git push --force origin rewind-commits

This is the final result:

cf80005 (HEAD -> rewind-commits, origin/rewind-commits) Added file1.txt
b00b937 Initial commit

Summary

Rewinding commits is a useful feature of Git that allows developers to undo changes and revert to a previous version of their code. By using the git reset command, developers can easily rewind their commits and get back to a previous version of their code. In this lab, you have learned how to use Git to rewind commits and get back to a previous version of your code.
