Quick Reference

Essential Commands

# Repository
git init                    # Initialize new repo
git clone <url>             # Clone remote repo

# Changes
git status                  # Check status
git add <file>              # Stage file
git commit -m "message"     # Commit staged changes

# Branches
git branch                  # List branches
git checkout -b <branch>    # Create and switch
git merge <branch>          # Merge branch

# Remote
git pull                    # Fetch and merge
git push                    # Push to remote
git fetch                   # Fetch without merge

Common Workflows

# Feature development
git checkout -b feature/new-feature
# ... make changes ...
git add .
git commit -m "feat: add new feature"
git push -u origin feature/new-feature
# Create PR, merge, delete branch

# Hotfix
git checkout main
git pull
git checkout -b hotfix/critical-bug
# ... fix bug ...
git commit -m "fix: resolve critical bug"
git push -u origin hotfix/critical-bug
# Create PR with priority review
