Git Remove Commit - Shell/Bash

As a programmer, you may sometimes need to remove a commit from your Git repository. This can be done using the "git revert" command, but that will create a new commit that undoes the changes made by the original commit. If you want to completely remove a commit from your repository history, you can use the "git rebase" command.

Here's how you can remove a commit using Git rebase in Shell/Bash:

1. Open your Git repository in a terminal window.
2. Run the following command to view your commit history:

git log

This will show you a list of all the commits in your repository, along with their SHA-1 hashes.

3. Copy the SHA-1 hash of the commit you want to remove.

4. Run the following command to initiate the interactive rebase mode:

git rebase -i HEAD~n

Replace "n" with the number of commits you want to go back. For example, if you want to remove the most recent commit, use "HEAD~1".

5. This will open a text editor with a list of all the commits before the one you want to remove. Find the commit you want to remove and delete its corresponding line from the file. Save and exit the editor.

6. If the commit you want to remove has already been pushed to a remote branch, you will need to use the "-f" or "--force" flag with the next command. This will overwrite the remote branch with your new commit history.

7. Finally, run the following command to apply your changes and remove the commit:

git rebase --continue

Your commit should now be removed from the repository history.

Note: Be careful when using Git rebase, as it can permanently delete commits from your repository. Always make sure to have a backup of your repository before making any major changes.

Conclusion

Removing a commit from your Git repository can be a useful tool for organizing your code history. Just be sure to follow best practices and use caution, as improper use of Git rebase can lead to data loss.
