When working on a Git project, it’s common to create multiple feature branches that get merged into the main branch (usually main or develop). Over time, these branches can clutter your local repository, even after they have been merged into the remote repository. To keep things clean and organized, it’s good practice to periodically remove these locally merged branches.
In this post, I will walk you through how to use Git to remove local branches that have been merged in the remote repository.
Why Clean Up Merged Branches?
Removing branches that have already been merged helps keep your Git workspace tidy and more manageable. It can also reduce potential confusion and prevent anyone from mistakenly checking out old, merged branches.
Step 1: List Local Merged Branches
First, let’s confirm which local branches have already been merged into the main branch on the remote repository.
Command to list merged branches:
git branch --merged
This will show a list of local branches that have been merged into the currently checked-out branch (usually main or develop). The list will also include the main branch itself, so be careful not to delete it!
For example:
feature-1
feature-2
main
This output shows that feature-1 and feature-2 have been merged into the main branch.
Step 2: Delete Merged Local Branches
To remove a specific branch that has been merged, use the following command:
git branch -d <branch_name>
For example:
git branch -d feature-1
This will safely delete feature-1 because it has already been merged. If you try to delete a branch that hasn’t been merged, Git will warn you to avoid losing any work.
Automating Branch Cleanup
To delete all local branches that have been merged, except for main (or your main branch of choice), you can run the following command:
git branch --merged | grep -v "\* main" | xargs -n 1 git branch -d
git branch --merged: Lists all branches that are merged.grep -v "\* main": Excludes themainbranch from the deletion process.xargs -n 1 git branch -d: Deletes each branch that was merged.
If your main branch is named something else (e.g., develop), replace main with the correct branch name.
Step 3: Prune Deleted Remote Branches
In some cases, you may still see branches locally that have already been deleted from the remote repository. To clean up local references to these deleted remote branches, run the following command:
git fetch --prune
This will remove any local tracking branches that no longer exist on the remote repository.
Conclusion
Cleaning up merged branches in Git is a quick way to maintain an organized workspace, especially when working on large projects with many feature branches. By using the git branch --merged command and deleting unnecessary branches, you can keep your local repository clean and avoid clutter.
If you’re working with a team, make sure to only delete branches that have been fully merged and are no longer needed. Happy coding!
