Identifying the Need for a Git Reset

Have you ever found yourself in a situation where, after making changes and pushing to the master branch, your code suddenly stops functioning correctly? In such cases, reverting to a previous, stable state of the code can be necessary to get your project back on track.

Another instance where a Git reset might be helpful is when you accidentally push sensitive information, such as API keys or passwords, to your repository. By performing a reset, you can remove those commits and protect your sensitive data.

After recognizing that my code became non-functional at a certain juncture:

Failed build process

I decide that reverting to a previous, stable state of the code and permanently removing all intermediary changes is the best course of action.

Understanding Git Reset and Its Implications

Git reset is a powerful command that allows you to revert your codebase back to a specific, earlier state. It’s crucial to understand the implications of performing a Git reset, especially when working in a collaborative environment with multiple contributors.

When you execute a Git reset, you essentially erase all the changes made after the specified commit. This action is irreversible, meaning once you perform a reset, there’s no turning back. Therefore, it’s essential to use Git reset with caution and ensure you have a proper backup strategy in place.

Locating the Last Known Good Commit

Before performing a Git reset, you need to identify the last known good state of your codebase. This is the commit where your code was functioning as expected, before the introduction of any problematic changes.

Last successful build

To identify the last known good state, I check the commit ID in my version control system, such as GitHub.

Commit ID

Executung the Git Reset Command

With the commit ID in hand, you can now proceed to perform the Git reset. Open your terminal or command prompt and navigate to your local Git repository. Then, execute the following command:

git reset --hard <commit-id>

Replace <commit-id> with the actual ID of the commit you want to revert to. For example:

git reset --hard ac55a49123456789

The --hard flag ensures that all changes made after the specified commit are permanently discarded. It’s important to double-check the commit ID before executing this command to avoid accidentally losing any important changes.

Pushing the Reset Changes to the Remote Repository

After performing the Git reset locally, you need to update the remote repository to reflect the changes. To do this, you’ll use the git push command with the --force flag:

git push --force

The --force flag is necessary because you’re essentially overwriting the remote repository’s history with your local changes. It’s crucial to communicate with your team members before forcing a push, as it can potentially disrupt their work if they have based their changes on the commits you are removing.

This process effectively erases the problematic changes and resets the repository as if the subsequent commits never occurred.


Dealing with Merge Conflicts After a Git Reset

In some cases, performing a Git reset might result in merge conflicts when other team members try to pull the latest changes. This happens because their local repository still contains the commits that you have removed.

To resolve merge conflicts, your team members will need to perform a git pull with the --rebase flag:

git pull --rebase

This command will apply their local changes on top of the reset commit, allowing them to resolve any conflicts and continue working with the updated codebase.

Exploring Alternative Approaches

While Git reset is a powerful tool, it’s not always the best solution. Before resorting to a reset, consider alternative approaches that might be less disruptive and more suitable for your specific situation.

Using Git Revert

For example, if you only need to revert a few specific commits, you can use the git revert command instead. This command creates a new commit that undoes the changes made in the specified commits, preserving the original commit history.

Creating a New Branch

Another alternative to Git reset is creating a new branch from the last known good commit. This approach allows you to explore and test changes without affecting the main branch.

To create a new branch, use the following command:

git checkout -b <new-branch-name> <commit-id>

Replace <new-branch-name> with a descriptive name for your new branch and <commit-id> with the ID of the commit you want to branch from.

Once you have created the new branch, you can cherry-pick specific commits from the problematic branch, applying only the desired changes. This selective approach gives you more control over the changes you introduce and minimizes the risk of discarding important work.

Stashing Changes

If you have uncommitted changes in your working directory that you want to temporarily set aside before performing a reset or switching branches, you can use Git’s stash feature.

To stash your changes, run the following command:

git stash

This command saves your uncommitted changes and reverts your working directory to match the HEAD commit. You can later retrieve the stashed changes using git stash apply or git stash pop.

Stashing provides a convenient way to save your work-in-progress without committing it, allowing you to switch contexts or perform other Git operations without losing your changes.

Interactive Rebasing

Interactive rebasing is a powerful technique that allows you to rewrite commit history by modifying, reordering, or squashing commits. While it’s not a direct alternative to Git reset, interactive rebasing can help you clean up your commit history and create a more linear and understandable progression of changes.

To start an interactive rebase, use the following command:

git rebase -i <commit-id>

Replace <commit-id> with the ID of the commit you want to start the rebase from. Git will open an editor where you can specify the actions to perform on each commit, such as pick, reword, squash, or drop.

Interactive rebasing requires a good understanding of Git and should be used with caution, as it rewrites the commit history. It’s most suitable for cleaning up local commits before pushing them to a shared repository.


Performing a Git reset to revert your codebase back to a previous commit is a straightforward two-step process. By identifying the last known good commit and executing the reset command, you can effectively remove problematic changes and restore your code to a stable state.

Remember, before proceeding with a hard reset, consider all implications and ensure you have an appropriate backup strategy in place for your repository.

By mastering various Git techniques and understanding their strengths and limitations, you can make informed decisions and maintain a clean, manageable, and efficient codebase.
