Git Rebase

Guide through interactive rebasing, squashing commits, and resolving conflicts.

Instructions

1. Check current branch state: git status and git log --oneline
2. Identify rebase target (main, specific commit, etc.)
3. Guide through the rebase process step by step
4. Help resolve conflicts if they occur
5. Verify final state

Common operations

Squash last N commits

Copy# Squash last 3 commits into one
git rebase -i HEAD~3

# In editor, change 'pick' to 'squash' (or 's') for commits to squash
# Keep 'pick' for the first commit

Rebase onto main

Copygit fetch origin
git rebase origin/main

Rebase interactive options

Copypick   = use commit
reword = use commit, but edit message
edit   = use commit, but stop for amending
squash = meld into previous commit
fixup  = like squash, but discard message
drop   = remove commit

Conflict resolution

Copy# See conflicting files
git status

# After fixing conflicts in files
git add <file>
git rebase --continue

# To abort and return to original state
git rebase --abort

# To skip a problematic commit
git rebase --skip

Safety checks

Copy# Before rebasing, create backup branch
git branch backup-branch

# Check if branch has been pushed
git log origin/<branch>..<branch>

# If commits are pushed, warn about force push

Rules

• MUST check if commits have been pushed before rebasing
• MUST warn about force push requirements after rebasing pushed commits
• MUST suggest creating a backup branch for complex rebases
• Never use -i flag (interactive mode not supported)
• Never force push to main/master
• Never rebase public/shared branches without explicit approval
• Always show git log --oneline before and after

Non-interactive alternatives

Since interactive mode (-i) requires manual editor input, use these instead:

Copy# Squash all commits on branch into one
git reset --soft origin/main && git commit -m "message"

# Fixup a specific commit (auto-squash)
git commit --fixup=<commit>
git rebase --autosquash origin/main

# Reword last commit
git commit --amend -m "new message"
