Git is one of the most popular version control systems in the world. It enables developers to work together on a single project, keep track of changes, and collaborate efficiently. One of the key features of Git is branching. Branches allow you to create multiple versions of your codebase, work on them simultaneously, and merge them back together when you’re ready. However, by default Git creates your main branch called "master”, which is used as the default for your repository. But what if you want to change your default branch? In this article, we'll show you how to change your default branch in Git with code examples.
Why Change Your Default Branch
By default, Git creates a branch called "master” when you create a new repository. This branch is considered the main branch of your repository. All the changes you make to your codebase will be part of this branch by default. However, the terminology "master” has many negative connotations, and thus has been rejected by many organizations. So, they have moved to a more neutral term such as "main” or "default”. In addition, Git community has decided to abandon the word "master” in favor of "main” as the default branch name. Therefore, if you want to use "main” instead of "master” as your default branch name, or any other name you prefer, you can follow the steps below.
Step 1: Create a New Branch
Before changing your default branch, you need to create a new branch with the name of your choice. You can create a new branch in Git using the following command:
git branch <branch-name>
For example, if you want to create a new branch called "main”, you can use the following command:
git branch main
Step 2: Push your new Branch to Remote
Once you have created a new branch, you need to push it to the remote. This will make it available for others to see and collaborate on. You can use the following command to push your new branch to remote:
git push -u origin <branch-name>
For example, if you want to push the "main” branch to the remote, you can use the following command:
git push -u origin main
Step 3: Set Your New Branch as Default
Now we are going to set your new branch as the default branch. For doing so, you need to run the following command:
git symbolic-ref refs/heads/<new-default-branch> refs/heads/<old-default-branch>
For example, to set "main” as your default branch, run the following command:
git symbolic-ref refs/heads/main refs/heads/master
Step 4: Update Your Local Repository
The last step is to update your local repository to reflect the changes you have made. You can do this by running the following command:
git pull
This will fetch all changes from the remote repository and merge them with your local repository.
Final Thoughts
In conclusion, changing your default branch in Git is an easy process. You just need to create a new branch, push it to the remote, set it as the default branch, and update your local repository. In addition, if you prefer to use a different name for your default branch, you can easily replace "main” with your preferred name when you execute the "symbolic-ref” command. By doing so, you can customize your default branch and build a more inclusive culture in your development team.

Git Branching
Git branching is a powerful feature that allows you to create separate versions of your codebase. This can be useful when working on features or bug fixes, or when experimenting with different approaches to a problem. Each branch in Git is essentially a separate copy of your codebase that you can work on independently of the other branches. When you're ready to merge your changes back into the main branch, Git provides powerful tools to help you automate the process.
Git branches are lightweight and easy to create. You can create a new branch at any time using the "git branch" command. For example:
git branch new-branch-name
This creates a new branch called "new-branch-name" but does not switch to it. You will need to use the "git checkout" command to switch to the new branch:
git checkout new-branch-name
Once you have switched to the new branch, you can work on it in the same way you work on the main branch. When you're ready to merge the changes back into the main branch, use the "git merge" command.
Changing the Default Branch in Git
As mentioned earlier, by default, Git creates a branch called "master" when you initialize a new repository. However, Git community and many organizations prefer using a more neutral term like "main" or "default" instead of "master". Therefore, if you want to use a different name for your default branch in Git, you can easily change it.
There are two ways to change the default branch in Git – via the GitLab/GitHub website or by using the Git command-line interface. Here's how to do it using the Git command-line interface:
- Create a new branch: Using the "git branch" command, create a new branch with a name of your choice. For example, if you want to use "default" as your default branch name, you can use the following command:
git branch default
- Push the new branch to remote: Using the "git push" command, push the new branch to your remote repository. For example:
git push -u origin default
- Set the new branch as the default: Using the "git symbolic-ref" command, set the new branch as the default branch. For example, to set the "default" branch as the new default branch, use the following command:
git symbolic-ref refs/heads/HEAD refs/heads/default
This command points the HEAD to the new default branch, which means that all future commits will be on this branch.
- Delete the old default branch: If you want to remove the old default branch, you can do so using the "git branch -d" command. For example:
git branch -d master
This command deletes the old "master" branch.
- Update your remote repository settings: Finally, you need to update your remote repository settings to use the new default branch as the primary branch. This can be done via the GitHub or GitLab website.
Summary
In summary, Git branching is a powerful feature that allows you to create multiple versions of your codebase. Changing the default branch in Git is an easy process that involves creating a new branch, pushing it to remote, setting it as the default branch, deleting the old branch, and updating your remote repository settings. By using a more neutral term for your default branch, you can help create a more inclusive development environment for your team.
Popular questions
Here are five potential questions one might ask about changing the default branch in Git, along with their answers:
-
What is the default branch in Git, and why would I want to change it?
The default branch in Git is the branch that is created automatically when you initialize a new repository. By default, this branch is named "master," but you may want to change it to a different name, such as "main" or "default", for various reasons. Some companies choose to rename the default branch in order to promote more inclusive language, since the term "master" can have negative connotations. -
How do I create a new branch in Git?
To create a new branch in Git, you can use the "git branch" command, followed by the desired branch name. For example, to create a new branch called "my-new-branch," you would type "git branch my-new-branch." Note that this command only creates the new branch locally; to push the branch to a remote repository, you would need to use the "git push" command. -
How do I set a new branch as the default in Git?
To set a new branch as the default in Git, you can use the "git symbolic-ref" command, followed by the "HEAD" reference and the name of your new default branch. For example, if you want to set a branch called "default" as the new default branch, you would type "git symbolic-ref refs/heads/HEAD refs/heads/default." This will make all new commits default to this branch. -
Can I delete the old default branch after setting a new one?
Yes, once you have set a new default branch in Git, you can safely delete the old default branch. To do so, use the "git branch -d" command followed by the name of the branch you want to delete. For example, to delete the old "master" branch, you would type "git branch -d master." Note that this command only deletes the branch locally; to delete the branch from a remote repository, you would need to use the "git push" command. -
Will changing the default branch in Git affect my existing commits or branches?
Changing the default branch in Git will not affect your existing commits or branches. However, any new commits you make after changing the default branch will be made to the new default branch by default. If you want to move existing commits to the new default branch, you can do so using the "git cherry-pick" or "git rebase" commands, but be aware that this can be a complex process and should be done carefully to avoid losing any work.
