Git Revert a Commit - Shell/Bash

Introduction

In Git, reverting a commit means to undo the changes that were made in a specific commit. This can be done using the git revert command in the terminal.

In this tutorial, we will walk through the steps of reverting a commit using the Git command line interface in a shell/bash environment.

Prerequisites

• Git installed on your computer
• Basic knowledge of the command line interface

Steps

1. Open your terminal or command prompt and navigate to the local repository where your commit is located.

2. Run the following command to view a list of all the commits in the repository:

   git log
   

   This will display a list of all the commits along with their commit hashes, messages, and other details.

3. Identify the commit that you want to revert by its hash. You can copy the commit hash to your clipboard for convenience.

4. Run the following command in your terminal, replacing COMMIT_HASH with the hash of the commit you want to revert:

   git revert COMMIT_HASH
   

   This will create a new commit that undoes the changes made in the specified commit.

5. Git will open your default text editor (usually Vim) to create a commit message for the revert commit. You can modify the message if you want, but it's not essential. Save and close the file to continue.

6. Once the commit message is saved, Git will create a new commit that undoes the changes made in the specified commit. You can verify this by running the git log command again and checking the commit history.

Conclusion

That's it! You have successfully reverted a commit using Git in a shell/bash environment. This is a useful feature that can be used to correct mistakes or undo unwanted changes in your Git repository. Remember to use caution when reverting changes, as it will permanently delete the specified commit and its associated changes.
