Rewind to a Specific Commit

Introduction

Git is a powerful version control system that allows developers to track changes made to their codebase. One of the most useful features of Git is the ability to rewind back to a specific commit. This can be helpful when you need to undo changes or revert to an earlier version of your code.

Rewind to a Specific Commit

As a developer, you may need to undo changes made to your codebase. For example, you may have made a mistake and need to go back to an earlier version of your code. In this challenge, you will use Git to rewind back to a specific commit in a repository.

To complete this lab, you will use the Git repository git-playground from https://github.com/labex-labs/git-playground.git. Follow these steps to complete the challenge:

1. Clone the repository to your local machine:

git clone https://github.com/labex-labs/git-playground.git

2. Navigate to the repository:

cd git-playground

3. View the commit history of the repository:

git log --oneline

4. Make sure that the commit message you want to rewind to is the "Initial commit" commit hash.
5. Use the command git reset <commit> to rewind back to the specified commit. For example, you want to rewind back to the commit with hash 3050fc0d3:

git reset 3050fc0d3

6. View the commit history of the repository again:

git log --oneline

7. If you want to delete the changes and revert to the earlier version of your code, use the command git reset --hard <commit>. For example, you want to delete the changes and revert to the commit with hash c0d30f305:

git reset --hard c0d30f305

This is the result of running git log --oneline:

c0d30f305 (HEAD -> master) Initial commit

Summary

Rewinding back to a specific commit is a useful feature of Git that allows developers to undo changes or revert to an earlier version of their code. In this lab, you used Git to rewind back to a specific commit in a repository. Remember to use git reset to rewind back to a specific commit and git reset --hard to delete changes and revert to an earlier version of your code.
