Common Workflows
Feature Branch Workflow
- Create a feature branch:
git checkout -b feature-name - Make changes and commit:
git add . and git commit -m "message" - Push to remote:
git push origin feature-name - Create pull request (via web interface)
- After review, merge to main branch
Fixing Mistakes
- Amend last commit:
git commit --amend - Undo last commit (keeping changes):
git reset HEAD~1 - Discard all local changes:
git reset --hard - Discard changes to a file:
git checkout -- <file>
