Step-by-Step Guide for Resolving Git Merge Conflicts
Resolving a Git merge conflict can seem challenging, but by breaking it down into these actionable steps, you’ll resolve conflicts like a pro.
1. Identify the Merge Conflict
Run the following command to determine the conflicted files:
git status
Example Output:
On branch main
You have unmerged paths.
(fix conflicts and run "git commit")
both modified: merge.txt
This indicates the file causing the conflict.
2. Locate the Conflicted File
Open the conflicted file in your preferred editor (e.g., VS Code, Vim, or nano).
Conflicted Content Example:
<<<<<<< HEAD
this is some content to mess with
content to append
=======
totally different content to merge later
>>>>>>> new_branch
3. Resolve the Conflict
Manually edit the file to keep the required changes and remove conflict markers (<<<<<<<, =======, >>>>>>>).
Resolved Content Example:
this is some content to mess with
content to append
totally different content to merge later
4. Stage the Resolved File
Once resolved, mark the file as resolved using:
git add <file>
Example:
git add merge.txt
5. Commit the Resolution
Commit your changes with a meaningful message:
git commit -m "Resolved merge conflict in merge.txt"
6. Advanced Debugging with Git Commands
When resolving tricky conflicts, these commands can come in handy:
- Check which commits caused conflicts:
git log --merge - Inspect differences in files:
git diff
7. Resolve Deleted File Conflicts
Sometimes, conflicts arise when one branch deleted a file, while the other modified it.
Command Options:
- To keep the file:
git add <file> - To delete the file:
git rm <file>
Complete the process by committing the changes:
git commit -m "Resolved file deletion conflict"
8. Use Git Merge Tools (Optional)
If manual resolution feels complex, leverage Git’s built-in merge tools:
git mergetool
This launches a graphical interface to guide you through resolving conflicts.
9. Finalize the Merge
Execute the merge commit to wrap up the process:
git commit
Resolution Using Tools
GitHub
- Create a Pull Request.
- Click Resolve Conflicts.
- Edit files online, save, and commit your updates.
VS Code
- Open conflicts automatically flagged in the IDE.
- Choose between options like Accept Current Changes or Accept Incoming Changes.
- Save files, stage them (
git add .), and commit.
Best Practices to Avoid Merge Conflicts
- Pull frequently:
git pull origin main - Work in small increments—commit often and avoid overlapping changes.
- Use descriptive commit messages to clarify intentions.
- Coordinate project workflows using communication tools like Slack, Jira, or Trello.

Expert Advice
From Personal Experience:
When resolving large-scale merge conflicts across multiple branches, split your work into smaller chunks. Tackle one file or section at a time instead of rushing through everything. This avoids missed errors and makes the process smoother.
Tools That Helped Me:
- MiniTool Power Data Recovery: Ideal for recovering accidentally deleted repositories or files.
- EaseUS Backup: Reliable for creating snapshots before major merges.
FAQs
1. What happens if I can’t resolve a conflict?
Use git merge --abort to stop the process and return to the branch’s original state. Start again after figuring out the root cause.
2. Can I undo a merge commit?
Yes, use:
git reset --hard <commit-hash>
Be cautious—this will discard changes since the specified commit.
3. Which tool is best for resolving conflicts?
Both VS Code’s Merge Editor and GitHub’s Conflict Editor are beginner-friendly.
4. Why do conflicts occur so often in my team?
Poor team coordination or working on the same files simultaneously causes conflicts. Set clear conventions and establish ownership of critical files or folders.
5. How can I review all conflicts at once?
Use:
git diff --name-only --diff-filter=U
This lists all files with unresolved conflicts.
With this guide and the proper tools, you’re well-equipped to resolve Git merge conflicts effectively. Stay consistent, communicate with your team, and practice best Git hygiene for smoother workflows.
