In this blog, we'll explore the fundamentals of Git, understanding what it is and why it's an essential tool. We'll also guide you through the process of installing and configuring Git on both Windows and Linux platforms, ensuring you're well-equipped to manage your projects effectively.

What is Git ?

Git is a distributed version control system designed to handle everything from small to very large projects with speed and efficiency. It allows multiple people to work on a project simultaneously without interfering with each other's changes. By tracking and recording every modification made to a project's files, Git enables users to easily collaborate, revert to previous versions, branch off to develop new features, and merge changes back into the main codebase.Git's powerful branching and merging features, along with its strong support from platforms like GitHub, GitLab, and Bitbucket, have made it the most popular version control system in the world.

Why use Git ?

Benefits of Git in Version Control:

Collaboration: Git allows multiple developers to work on the same project simultaneously without overwriting each other's changes.
Version Tracking: Every change is tracked, allowing you to revert to previous versions if needed.
Branching and Merging: Git’s branching model lets you create separate branches for new features, bug fixes, or experiments, which can later be merged back into the main project.
Distributed System: Each developer has a complete copy of the project history, making Git resilient to data loss and enabling work offline.

Setting Up Git on Windows

Step 1: Download Git

Go to the official Git website: https://git-scm.com/.
Choose the Windows version and download the installer.

Step 2: Install Git

Run the downloaded installer.
Guide through the installation process:
- Default settings for most users.
- On the 'Select Components' page make sure to check
  
  ✔️ Add a git bash profile to Windows Terminal
  
  This will significantly improve your experience.
- Choosing the default editor (e.g., Vim, Notepad++).
- On the 'Choose a Credential Helper' page
  Choose Git Credential Manager
  Again, this will be helpful later when we configure Git.
- Configuring the initial branch name.

Step 3: Verify Installation

Open Command Prompt / Windows Terminal or Git Bash.
Run git --version to confirm Git is installed correctly.

Step 4: Configure Git

Set your username: git config --global user.name "Your Name".
Set your email: git config --global user.email "your.email@example.com".
Verify configuration: git config --list.

Setting Up Git on Linux

Step 1: Install Git

For Ubuntu/Debian-based distributions:
- Open Terminal.
- Run sudo apt-get update.
- Install Git: sudo apt-get install git.
For Fedora-based distributions:
- Open Terminal.
- Run sudo dnf install git.
For Arch-based distributions:
- Open Terminal.
- Run sudo pacman -S git.

Step 2: Verify Installation

Run git --version in Terminal to ensure Git is installed correctly.

Step 3: Configure Git

Set your username: git config --global user.name "Your Name".
Set your email: git config --global user.email "your.email@example.com".
Verify configuration: git config --list.

Basic Git Commands to Get Started

Initialize a Repository
- git init – Start a new Git repository.
Cloning a Repository
- git clone <repository-url> – Clone an existing repository.
Checking Repository Status
- git status – Check the current state of the repository.

Staging and Committing Changes

git add <file> – Stage changes.
git commit -m "commit message" – Commit changes with a message.
