If you are a developer or involved in software development, you have probably come across the term “squashing commits” in your work with Git. But what exactly is squashing commits, and why is it important for maintaining clean and organized code in software development projects?
In simple terms, squashing commits means combining multiple commits into a single, more concise commit. The purpose of this process is to reduce the size of the commit history and simplify the process of code review. By condensing Git commit history, developers can better manage their project history and collaborate more efficiently with other team members.
Reducing Git commit history also provides several other benefits, such as improving project readability and simplifying debugging. By squashing commits, developers can easily identify where changes have been made and why, which helps to streamline the development process and reduce the potential for errors or bugs.

Squashing Commits in Git: A Step-by-Step Guide
If you’re looking to clean up your Git commit history and simplify the process of code review, squashing commits could be the solution you need. Here’s our step-by-step guide on how to squash commits in Git.
- Make sure your local repository is up-to-date with the remote repository by running git pull in your terminal.
- Run git log to view your commit history and identify the commits you want to squash.
- Copy the hash of the commit immediately before the first commit you want to squash.
- Run git rebase -i followed by the hash you just copied.
- A text editor will open with a list of your selected commits. Change the word “pick” to “squash” for each commit you want to squash.
- Save and close the text editor to continue.
- Another text editor will open with the combined commit message. Edit the message as needed, then save and close the editor.
- Run git push –force to update the remote repository with your squashed commits.
That’s it! You’ve successfully squashed your commits in Git. Remember to communicate with your team before using the –force command, as it can overwrite existing commits and cause conflicts.
Benefits of Squashing Commits: Why It’s Worth It
Squashing commits in Git may seem like an extra step in the development process, but it can provide numerous benefits for your project.
One of the most important advantages is Git history clean-up. By squashing commits, you can reduce the size of your Git commit history, which can lead to faster repository operations and a more efficient development workflow. Plus, having a cleaner Git history makes it easier to find and fix bugs, implement new features, and collaborate with other developers.
Another benefit of squashing commits is that it helps improve project readability. Instead of having multiple commits with vague or confusing commit messages, you can create a single, concise commit that accurately reflects the changes made. This can simplify the process of code review and make it easier to understand the evolution of the project over time.
Lastly, squashing commits can help streamline collaboration with other developers. By maintaining a clean and organized Git commit history, team members can quickly determine which changes have been made and how they relate to other parts of the project. This can save time and reduce the risk of conflicts and mistakes.
If you’re wondering why squash commits, the benefits are clear: reducing Git commit history, improving project readability, and streamlining collaboration with other developers. By implementing this practice in your software development projects, you can maintain clean and organized code and optimize your development workflow.
Merging Commits in Git: The Alternative Approach
While squashing commits can be a useful practice in Git, it might not be the best approach in every scenario. Sometimes, merging commits might be preferred over squashing them. When a project has multiple contributors or involves long-lived feature branches, it might be more appropriate to merge commits to ensure that all contributors receive credit for their work. Merging commits can also be useful when it is important to preserve the history of the project.
To merge commits in Git, start by switching to the branch where you want to merge the commits. Then, enter the following command:
git merge <source-branch>
Replace <source-branch> with the name of the branch you want to merge into your current branch. Git will automatically create a new merge commit that combines the changes from both branches. If you encounter any merge conflicts, Git will prompt you to resolve them before you can complete the merge process.
It is important to note that merging commits can result in a messier commit history than squashing commits. To mitigate this, consider using descriptive commit messages and organizing related changes into separate commits when possible.
Strategies for Git History Clean-Up
While squashing commits is a great technique for reducing Git commit history, there are other strategies you can implement to keep your project history concise and organized.
Rebasing is another technique you can use to clean up your Git history. With this technique, you can reapply a series of commits onto a different base commit, effectively rewriting your project history. Rebasing can help you resolve conflicts more efficiently and create a more linear project history.
If you need to make changes to a previous commit, you can use the Git commit –amend command. This will allow you to modify the most recent commit with new changes without creating a new commit. This results in fewer unnecessary commits in your Git history.
The interactive rebase feature in Git allows you to modify your commit history by reordering, modifying, or removing commits. This can help you condense your Git history and create a more streamlined project history. Use the Git rebase -i command to access interactive rebase.
By using these additional strategies for Git history clean-up, you can reduce the size of your Git commit history and maintain a more concise and manageable project history.
Expert Tips for Condensing Git Commits
Reducing Git commit history and condensing Git commits can be a daunting task, but by following some expert tips, developers can make the process easier and more effective.
Structure Commits for Clarity
When creating commits, it’s important to structure them in a way that is clear and understandable. Keep related changes together in a single commit and use meaningful commit messages that describe the changes made. This will help other team members easily understand the purpose of each commit and aid in debugging if issues arise.
Use Git’s Interactive Rebase Feature
Git’s interactive rebase feature is a powerful tool that can help condense multiple commits into a single, cohesive commit. Use the interactive rebase feature to easily combine related commits and remove unnecessary or duplicate changes. This will help keep the commit history clean and organized.
Amend Commits When Necessary
If a commit contains a mistake or needs to be modified, use Git’s amend feature to make changes without creating a new commit. This can help keep the commit history concise and prevent cluttering with unnecessary commits.
Group Related Changes Together
When making changes to multiple files, group related changes together in a single commit. This will help keep the commit history organized and make it easier to track changes over time. Use the
--patch flag to review and select changes to include in each commit.
Use Meaningful Commit Messages
When creating commit messages, use descriptive language that accurately conveys the changes made in the commit. Avoid using vague or generic commit messages like “Updated code” or “Fixed bugs”. Instead, use specific language that describes the changes made and why they were necessary.
By utilizing these expert tips, developers can effectively reduce Git commit history and condense Git commits, leading to a cleaner, more organized project history.
It’s clear that squashing commits can be a valuable technique for maintaining organized and readable code in software development projects. By condensing multiple commits into a single, logical commit, developers can simplify the process of code review and improve collaboration with other team members.
But squashing commits is just one strategy for optimizing your Git history. There are other approaches, like merging commits or using Git’s interactive rebase feature, that can be more appropriate in certain situations.
