Git is a distributed version control system. Tracks changes in source code during software development. Helps teams collaborate on code. 🧰 Installing Git For Linux: sudo apt update sudo apt install git For macOS: brew install git For Windows: Download from: https://git-scm.com/downloads ⚙️ Git Configuration git config --global user.name "Your Name" git config --global user.email "you@example.com" git config --list # verify settings 🔄 Basic Git Workflow git init # Initialize a Git repository git status # Check current status git add file.txt # Stage a file git commit -m "Added file" # Commit with message 🧬 Cloning a Repository git clone https://github.com/yourusername/project.git ✍️ Making Changes & Committing echo "Hello Git" > hello.txt git add hello.txt git commit -m "Added hello.txt file" 🌿 Branching and Merging git branch # List branches git branch feature-x # Create a new branch git checkout feature-x # Switch to branch # Make changes and commit git checkout main git merge feature-x # Merge branch into main 🔄 Real-Time Example: Feature Branch Workflow Scenario: You are adding a login feature.

🔍 Advanced git log Examples git log is highly customizable. Here are real-world examples: 📦 Basic Commit Log git log Shows full commit history with author, date, and message. 🧵 One-line Log (Condensed View) git log --oneline Shows each commit as a single line: useful for quick scanning. 🌲 Visual Branch Graph git log --oneline --graph --all Displays commit history as a branch graph across all branches.

Learn branching, logs, reset, and collaboration with remotes. Practice makes perfect!

Git Rebase and Merge

🧩 Git Merge Methods Explained 🔸 1. Fast-Forward Merge 📌 What: Moves the branch pointer forward because there’s no divergent history. 🧪 Example: git checkout main git merge feature-branch ✅ If main is behind feature-branch but has no new commits, Git just moves main forward — no merge commit is created. 📊 Result: No extra commit. Clean history. Only possible when histories are linear (no parallel commits). 🔸 2. Three-Way Merge (Default) 📌 What: Used when branches diverged — Git creates a merge commit.
