# Git Cheat Sheet

## Basics

- **Initialize a Git Repository**: `git init`
- **Clone a Repository**: `git clone <repository-url>`
- **Check Repository Status**: `git status`
- **Add Changes to Staging Area**: `git add <file>` or `git add .` (for all changes)
- **Commit Changes**: `git commit -m "Commit message"`
- **View Commit History**: `git log`
- **Undo Last Commit (Keep Changes)**: `git reset HEAD~1`
- **Discard Changes in Working Directory**: `git checkout -- <file>`
- **Create a Branch**: `git checkout -b <branch-name>`
- **Switch Branches**: `git checkout <branch-name>`
- **Merge Branch**: `git merge <branch-name>`

## Branching and Merging

- **List Branches**: `git branch`
- **Delete a Branch (Locally)**: `git branch -d <branch-name>`
- **Delete a Branch (Force)**: `git branch -D <branch-name>`
- **Merge Branch into Current Branch**: `git merge <branch-name>`
- **Merge Branch with Fast-Forward**: `git merge --ff-only <branch-name>`
- **Rebase Current Branch onto Another Branch**: `git rebase <branch-name>`
- **Abort a Merge/Rebase**: `git merge --abort` or `git rebase --abort`
- **View Merged/Rebased Commits**: `git reflog`

## Remote Repositories

- **Add a Remote Repository**: `git remote add <remote-name> <repository-url>`
- **List Remote Repositories**: `git remote -v`
- **Fetch Changes from a Remote Repository**: `git fetch <remote-name>`
- **Pull Changes from a Remote Repository**: `git pull <remote-name> <branch-name>`
- **Push Changes to a Remote Repository**: `git push <remote-name> <branch-name>`
- **Remove a Remote**: `git remote remove <remote-name>`

## Collaborative Work

- **Create a Pull Request**: Open one on your Git hosting platform.
- **Review and Merge Pull Request**: Done via the hosting platform.
- **Sync Fork with Upstream Repository**: `git fetch upstream`, `git merge upstream/main`

- **Revert a Commit**: `git revert <commit-hash>`
- **View Commit History**: `git log`
- **Show Changes in a Specific Commit**: `git show <commit-hash>`
- **View Differences Between Branches**: `git diff <branch1> <branch2>`

## Stashing

- **Stash Changes**: `git stash`
- **List Stashes**: `git stash list`
- **Apply Stash**: `git stash apply` or `git stash pop`
- **Delete Stash**: `git stash drop <stash-id>`

## Git Config

- **Set User Name**: `git config --global user.name "Your Name"`
- **Set User Email**: `git config --global user.email "[e-mail]"`
- **View Git Config**: `git config --list`
