Git is a powerful and flexible version control system that offers a wide range of features to manage your project’s source code. One of the most useful features in Git is the ability to squash commits, which allows you to merge multiple commits into a single one. This technique can help you simplify your project’s version control history, making it easier to manage and collaborate with others. In this tutorial, we’ll guide you through the process of squashing Git commits step-by-step, so you can master this technique.

Understanding Git Commits and Their Importance
If you’re new to Git, it’s essential to understand what commits are and why they’re crucial for version control. Commits are snapshots of the changes you make to your codebase over time. They are like milestones that help you keep track of your progress.
When you commit changes to your codebase, Git records the differences between the current version and the previous one. This process makes it easy to track changes, revert to previous versions, and collaborate with others.
Commits are also essential for keeping your codebase organized and understandable. By breaking your work into smaller, more manageable chunks, you can improve the readability of your commit history. This organization can make it easier for you and your team to understand the evolution of your codebase.
However, too many small commits can clutter your version control history, making it challenging to understand. That’s where squashing commits comes in.
Squashing commits allows you to combine multiple smaller commits into a single, more significant commit. This process helps simplify your version control history, making it easier to read and understand.
Squashing commits is particularly helpful in situations where you want to tidy up your commit history or provide a cleaner, more concise overview of your changes. It’s also useful when you want to merge changes from a branch back into the master branch.
In the next section, we’ll explore the benefits of squashing commits in more detail and explain how to do it.
The Benefits of Squashing Commits
If you want to manage your version control effectively, you need to know how to squash commits. This technique can simplify your version control history, making it easier to read and collaborate with others. In this section, we’ll explore the advantages of using Git rebase squash, Git merge squash, and Git squash and merge.
Git Rebase Squash
Git rebase squash is a powerful way of combining multiple commits into a single one. This approach allows you to edit the commit message and remove any unnecessary messages, ensuring your version control history is concise and clear. By using Git rebase squash, you can create a cleaner history and make your codebase more maintainable.
Git Merge Squash
If you prefer to use Git merge instead of Git rebase, you can still squash commits. Git merge squash allows you to combine a series of commits into a single one, just like Git rebase. However, instead of editing the commit message, you can choose to keep the original message or create a new one. Git merge squash is an excellent option for teams who prefer to use a merge-based workflow instead of a rebase-based one.
Git Squash and Merge
Git squash and merge is a combination of the two previous approaches. It allows you to merge your changes while also squashing any unnecessary commits. This approach can be beneficial for teams who want to keep a clean history while also using a merge-based workflow. By using Git squash and merge, you can create a clear and concise history of your codebase.
So, whether you prefer Git rebase squash, Git merge squash, or Git squash and merge, squashing commits can make a big difference in managing your version control history. By removing unnecessary or redundant commits, you can keep your history concise and easy to understand.
How to Squash Commits Using Git Rebase
If you’re looking to simplify your version control history and make it more readable, squashing commits can help. Git rebase is an efficient method for squashing commits. In this tutorial, we’ll walk you through the process step-by-step.
Before we begin, ensure you have a good understanding of the Git rebase concept, identified the commits to squash, and have a backup of your codebase.
- Step 1: Check out the branch – Start by checking out the branch you want to rebase and squash.
git checkout <branch-name> - Step 2: Initiate the rebase process – Use the “interactive” mode to initiate the rebase process and specify how many commits to squash.
git rebase -i HEAD~<number-of-commits-to-squash> - Step 3: Squash commits – In the editor, identify the commits you want to squash and replace “pick” with “squash”. Save and close the editor.
# This is a combination of <number> commits.
# The first commit’s message is:
pick 8fcb806 Added new feature XYZ
# This is the 2nd commit message:
squash 6c9bce2 Fixed bug in feature XYZ
# … - Step 4: Edit commit message – Edit the resulting commit message to describe your changes concisely. Save and close the editor.
i<edit-commit-message> - Step 5: Push changes – Finally, push the changes to the repository.
git push --force
You’ve now successfully squashed commits using Git rebase. Practice this technique regularly to keep your version control history clean and organized.
Squashing Commits with Git Merge
In addition to using Git rebase to squash commits, you can also use the Git merge command. The process is similar, but there are a few key differences to keep in mind.
To begin, create a new branch from the one you want to modify:
git checkout -b new-branch-name
Next, use the Git merge command with the –squash option followed by the branch you want to squash:
git merge –squash branch-to-squash
This will merge all the changes from the specified branch into your new branch without creating a new commit. You can now commit the changes as a single squashed commit:
git commit -m “Squashed commit message”
Once you’ve committed the changes, you can delete the branch you created earlier:
git branch -d new-branch-name
It’s important to note that when using Git merge to squash commits, the resulting commit will retain the original commit messages from the squashed branch. If you want to customize the commit message, you’ll need to use the Git commit –amend command:
git commit –amend -m “New commit message”
Overall, the Git merge approach to squashing commits is a viable alternative to using Git rebase. However, it’s worth noting that some developers prefer one method over the other, so it’s important to choose the one that works best for you and your team.
Squashing Multiple Commits in Git
Sometimes, you may find that you have multiple commits that are closely related to each other, and you want to squash them into a single commit. This can be useful for keeping your commit history clean and organized, making it easier to understand changes and collaborate effectively with other developers.
To squash multiple commits into one, you can use the interactive rebase feature of Git. This allows you to edit or combine commits in your history, including squashing them together.
Here’s how to do it:
- Open your terminal and navigate to the repository that contains the commits you want to squash.
- Run the command git rebase -i HEAD~x, replacing x with the number of commits you want to include in the rebase. This will open an interactive console.
- Find the first commit you want to squash and change the word pick to squash in front of its SHA hash.
- Save and close the console. This will initiate the rebase process.
- If there are any conflicts, resolve them and continue the rebase by running git rebase –continue.
- Once the rebase is complete, use the command git log to verify that the squashed commits have been combined into a single commit.
- Finally, force push the changes to the remote repository using git push –force.
It’s worth noting that while squashing commits can help keep your history clean, it’s important to use it judiciously. If you squash too many commits together, it can make it difficult to understand the changes that were made and why.
So, when you’re squashing commits, be sure to consider the context and the impact on future collaborators. With some practice and careful consideration, you’ll be able to use this technique to keep your Git history organized and efficient.
