🐧 Installing Git on Linux

Git is included in most Linux distribution repositories.
Use the appropriate command for your distribution to install Git via the terminal:

sudo apt install git         # Debian / Ubuntu
sudo dnf install git         # Fedora 22 and later
sudo yum install git         # Red Hat
sudo pacman -S git           # Arch Linux

Tip: You might need administrator privileges (using sudo) to install packages.

🍎 Installing Git on macOS

You can install Git on macOS in two main ways:

• Xcode Command Line Tools (recommended for most users):

  xcode-select --install
  

• Homebrew (if you already have it installed):

  brew install git
  

  Download details are available here: Git for macOS.

🪟 Installing Git on Windows

Download the latest Git installer from the official site: Git for Windows.

Alternatively, use these package managers in your Command Prompt or PowerShell: Winget:

winget install git

Chocolatey:

choco install git.install

⚙️ Basic Git Configuration

After installation, configure Git to identify your commits with your name and email:

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

Example

git config --global user.name Anoop Kumar
git config --global user.email anoopkumar1119@gmail.com

Why configure this ?
Your username and email appear in the commit history, helping teams track who made changes. Setting an editor ensures you can easily write commit messages.

Example

commit ff479ca6e8b37785329f28617dcd5fc953875a2b
Author: Anoop Kumar <anoopkumar1119@gmail.com>
Date:   Fri Jun 6 06:53:48 2025 +0200

Set your preferred text editor for commit messages and other Git actions:

• On Linux/macOS (example: nano):

  git config --global core.editor nano
  

• On Windows (example: Notepad++):

  git config --global core.editor "'C:/Program Files/Notepad++/notepad++.exe' -multiInst -notabbar -nosession -noPlugin"
  

  Verify your configuration settings anytime with:

  git config --list
  

Example

core.editor="C:\\Program Files\\Notepad++\\notepad++.exe" -multiInst -notabbar -nosession -noPlugin
user.name=Anoop Kumar
user.email=anoopkumar1119@gmail.com

📚 Getting Started with Git

Initialize a new Git repository inside any project folder with:

git init

This creates a .git directory that tracks changes and prepares your project for version control.

🛠 Troubleshooting Tips

• Check Git Installation: Run git --version to confirm Git is installed and see its version.
• Permission Issues: If installation commands fail, ensure you have administrator/root privileges.
• Windows PATH Problems: If Git commands aren’t recognized after installation, make sure Git’s bin directory is added to your system’s PATH.
