In this section, we will cover the steps required to install Git on different operating systems. By the end of this section, you will have Git installed and ready to use on your machine.

1. Installing Git on Windows
2. Installing Git on macOS
3. Installing Git on Linux
4. Verifying the Installation

1. Download the Git Installer:

   • Go to the official Git website: https://git-scm.com/
   • Click on the "Download" button for Windows.

2. Run the Installer:

   • Locate the downloaded .exe file and double-click to run it.
   • Follow the installation wizard. You can generally accept the default settings, but here are a few key points:
     • Select Components: Ensure "Git Bash Here" and "Git GUI Here" are selected.
     • Adjusting your PATH environment: Choose "Use Git from the command line and also from 3rd-party software".
     • Configuring the line ending conversions: Choose "Checkout Windows-style, commit Unix-style line endings".

3. Complete the Installation:

   • Click "Install" and wait for the process to complete.
   • Once done, click "Finish".

This command should output the installed Git version, confirming the installation.

1. Using Homebrew (Recommended):

   • If you don't have Homebrew installed, you can install it by running the following command in the Terminal:

     /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
     

   • Once Homebrew is installed, install Git by running:

     brew install git
     

2. Using the Git Installer:

   • Go to the official Git website: https://git-scm.com/
   • Click on the "Download" button for macOS.

1. Using Package Managers:

   • Debian/Ubuntu:

     sudo apt update
     sudo apt install git
     

   • Fedora:

     sudo dnf install git
     

   • Arch Linux:

     sudo pacman -S git

   • Extract the tarball and navigate to the directory:

     tar -xf git-<version>.tar.gz
     cd git-<version>
     

   • Compile and install:

     make prefix=/usr/local all
     sudo make prefix=/usr/local install
     

This command should output the installed Git version, confirming the installation.
