Git Advanced Workflows
Master advanced Git techniques to maintain clean history, collaborate effectively, and recover from any situation with confidence.
When to Use This Skill
- Cleaning up commit history before merging
- Applying specific commits across branches
- Finding commits that introduced bugs
- Working on multiple features simultaneously
- Recovering from Git mistakes or lost commits
- Managing complex branch workflows
- Preparing clean PRs for review
- Synchronizing diverged branches
Core Concepts
1. Interactive Rebase
Interactive rebase is the Swiss Army knife of Git history editing.
Common Operations:
pick: Keep commit as-isreword: Change commit messageedit: Amend commit contentsquash: Combine with previous commitfixup: Like squash but discard messagedrop: Remove commit entirely
Basic Usage:
# Rebase last 5 commits
git rebase -i HEAD~5
# Rebase all commits on current branch
git rebase -i $(git merge-base HEAD main)
# Rebase onto specific commit
git rebase -i abc123
2. Cherry-Picking
Apply specific commits from one branch to another without merging entire branches.
# Cherry-pick single commit
git cherry-pick abc123
# Cherry-pick range of commits (exclusive start)
git cherry-pick abc123..def456
# Cherry-pick without committing (stage changes only)
git cherry-pick -n abc123
# Cherry-pick and edit commit message
git cherry-pick -e abc123
3. Git Bisect
Binary search through commit history to find the commit that introduced a bug.
# Start bisect
git bisect start
# Mark current commit as bad
git bisect bad
# Mark known good commit
git bisect good v1.0.0
# Git will checkout middle commit - test it
# Then mark as good or bad
git bisect good # or: git bisect bad
# Continue until bug found
# When done
git bisect reset
Automated Bisect:
# Use script to test automatically
git bisect start HEAD v1.0.0
git bisect run ./test.sh
# test.sh should exit 0 for good, 1-127 (except 125) for bad
4. Worktrees
Work on multiple branches simultaneously without stashing or switching.
# List existing worktrees
git worktree list
# Add new worktree for feature branch
git worktree add ../project-feature feature/new-feature
# Add worktree and create new branch
git worktree add -b bugfix/urgent ../project-hotfix main
# Remove worktree
git worktree remove ../project-feature
# Prune stale worktrees
git worktree prune
5. Reflog
Your safety net - tracks all ref movements, even deleted commits.
# View reflog
git reflog
# View reflog for specific branch
git reflog show feature/branch
# Restore deleted commit
git reflog
# Find commit hash
git checkout abc123
git branch recovered-branch
# Restore deleted branch
git reflog
git branch deleted-branch abc123

Best Practices
- Always Use --force-with-lease: Safer than --force, prevents overwriting others' work
- Rebase Only Local Commits: Don't rebase commits that have been pushed and shared
- Descriptive Commit Messages: Future you will thank present you
- Atomic Commits: Each commit should be a single logical change
- Test Before Force Push: Ensure history rewrite didn't break anything
- Keep Reflog Aware: Remember reflog is your safety net for 90 days
- Branch Before Risky Operations: Create backup branch before complex rebases
# Safe force push
git push --force-with-lease origin feature/branch
# Create backup before risky operation
git branch backup-branch
git rebase -i main
# If something goes wrong
git reset --hard backup-branch
Common Pitfalls
- Rebasing Public Branches: Causes history conflicts for collaborators
- Force Pushing Without Lease: Can overwrite teammate's work
- Losing Work in Rebase: Resolve conflicts carefully, test after rebase
- Forgetting Worktree Cleanup: Orphaned worktrees consume disk space
- Not Backing Up Before Experiment: Always create safety branch
- Bisect on Dirty Working Directory: Commit or stash before bisecting
Recovery Commands
# Abort operations in progress
git rebase --abort
git merge --abort
git cherry-pick --abort
git bisect reset
# Restore file to version from specific commit
git restore --source=abc123 path/to/file
# Undo last commit but keep changes
git reset --soft HEAD^
# Undo last commit and discard changes
git reset --hard HEAD^
# Recover deleted branch (within 90 days)
git reflog
git branch recovered-branch abc123
