Git Rebase Conflict Cheat Sheet: Resolve Errors in 5 Minutes

Ever started a rebase, got a red error screen, and felt the whole day slip away? You’re not alone. A stray conflict can turn a quick merge into a nightmare, but with the right steps you can be back on track before lunch.

Why Rebase Conflicts Happen

A rebase rewrites history. Git takes each of your commits and tries to replay them on top of another branch. If the same lines were changed in both places, Git stops and asks you to decide which version wins. The conflict itself is not a bug – it’s Git’s way of saying “I need help”.

Common triggers

• Parallel edits – Two teammates edited the same function in different branches.
• File moves – One branch renamed a file while the other edited it.
• Whitespace changes – Some tools auto‑format code, causing line‑level differences.

Understanding the why makes the how a lot easier.

The 5‑Minute Rescue Plan

Below is a cheat‑sheet style flow you can keep in a terminal tab. Follow it step by step and you’ll resolve most rebase conflicts without breaking a sweat.

1. Pause and Inspect

git status

Git will list the files with conflicts and mark them as both modified. Take a quick look at the list; if you see only one or two files, you’re already in a good spot.

2. Open the conflicted file

Most editors highlight conflict markers:

<<<<<<< HEAD
code from the branch you are rebasing onto
=======
code from your branch
>>>>>>> feature-branch

Delete the markers and keep the version you want. If you need a mix, copy the good parts together, then delete the rest.

Pro tip: I use code -r <file> (VS Code) because the red highlights make the markers pop out instantly.

3. Mark the file as resolved

git add <file>

Adding tells Git you have fixed that file. Do this for each conflicted file.

4. Continue the rebase

git rebase --continue

Git will move on to the next commit. If another conflict appears, repeat steps 2‑4. Most small rebases finish after one or two rounds.

5. Abort if things go sideways

If you feel lost, you can always back out:

git rebase --abort

Your branch returns to the state before the rebase started. Then you can try a different strategy, like merging instead.

Tips to Avoid Future Conflicts

1. Pull often – Run git pull --rebase before you start work. It keeps your branch up‑to‑date and reduces the chance of overlapping changes.
2. Small commits – The smaller the change, the easier Git can auto‑merge. Break large features into logical chunks.
3. Consistent formatting – Agree on a formatter (Prettier, Black, clang‑format) and run it in a pre‑commit hook. That way whitespace won’t surprise you.
4. Communicate – If you know you’ll touch a hot file, drop a quick Slack note. A heads‑up can save everyone a conflict.

My Personal Story

The first time I tried a rebase on a shared repo, I was in the middle of a coffee break. My laptop beeped, the terminal filled with conflict markers, and I stared at the screen like it was a foreign language. I opened the file in my editor, stared at the <<<<<<< line, and thought, “Why does Git look like a broken heart?” After a few minutes of copy‑pasting, I realized the conflict was just a missing semicolon. I added it, ran git add, and the rebase finished. The lesson? A rebase is not a monster; it’s just a careful assistant asking for clarification.

TL;DR Checklist

• Run git status → see conflicted files.
• Open each file, remove <<<<<<<, =======, >>>>>>>.
• Keep the code you need, delete the rest.
• git add <file> for each resolved file.
• git rebase --continue (or --abort if you’re stuck).

Follow these steps, and you’ll be back to coding in under five minutes, even when the conflict monster shows up.
