Whether you’re a beginner or an experienced developer, mastering Git & GitHub is essential for efficient version control. Below is a comprehensive cheat sheet covering basic to advanced commands, along with practical examples.
Basic Git Commands
1. Initialize a Repository
git init
2. Clone a Repository
git clone <repository-url>
3. Check Repository Status
git status
4. Stage Changes
git add <file> git add . Stage all changes
5. Commit Changes
git commit -m "Your commit message"
6. Push to Remote Repository
git push origin <branch-name>
Branching & Merging
1. Create a New Branch
git branch <branch-name>
2. Switch to a Branch
git checkout <branch-name>
3. Merge Branches
git merge <branch-name>
4. Delete a Branch
git branch -d <branch-name>
Advanced Git Commands
1. View Commit History
git log git log --oneline Compact view
2. Undo Last Commit (Keep Changes)
git reset --soft HEAD~1
3. Undo Last Commit (Discard Changes)
git reset --hard HEAD~1
4. Stash Changes Temporarily
git stash git stash pop Restore stashed changes
GitHub Collaboration
1. Fork a Repository
- Click Fork on GitHub.
2. Create a Pull Request (PR)
- Push changes to your fork, then open a PR on GitHub.
3. Sync Fork with Upstream
git remote add upstream <original-repo-url> git fetch upstream git merge upstream/main
You Should Know:
- Rebasing vs. Merging
– `git rebase` rewrites commit history for a cleaner log.
– `git merge` preserves history but can create merge commits. - Handling Conflicts
- Use `git diff` to identify conflicts.
- Manually resolve conflicts, then `git add` and
git commit. - Git Aliases for Speed
git config --global alias.co checkout git config --global alias.br branch git config --global alias.ci commit
