Introduction

Git is a powerful version control system that helps developers track changes in their code, collaborate with teams, and maintain a clean development workflow. Whether working solo or as part of a team, learning Git is essential for efficient project management.

Why Learn Git?

• Track Changes: Git allows you to keep a history of all changes, making it easy to revert to previous versions.
• Collaboration: Multiple developers can work on the same project without conflicts.
• Backup & Restore: Your code is safe and recoverable.
• Branching & Merging: Work on different features independently and merge them when ready.
• Widely Used: Git is the most popular version control system, with platforms like GitHub, GitLab, and Bitbucket supporting it.

Getting Started with Git

1. Install Git

Before using Git, you need to install it on your system.

Mac (Using Homebrew)

brew install git

Windows

Download and install from git-scm.com.

Linux (Debian-based)

sudo apt install git

2. Configure Git

Set up your name and email (used for commits):

git config --global user.name "Your Name"  
git config --global user.email "your.email@example.com"  

To check your configuration:

git config --list

3. Initialize a Git Repository

To start tracking a project with Git:

git init

This creates a hidden .git folder that stores version history.

Add Files to Staging Area

git add filename

To add all files:

git add .

Commit Changes

git commit -m "Initial commit"

Commits save the changes locally with a message describing them.

View Commit History

git log

Create a Branch

git branch new-feature

Switch to Another Branch

git checkout new-feature

or

git switch new-feature

Merge Branches

git checkout main  
git merge new-feature

Clone a Repository

git clone https://github.com/user/repo.git

Push to Remote Repository

git push origin main

Pull Latest Changes

git pull origin main
