💻 Install Git

<- Previous: Introduction Next: Configure Your Git Identity ->

🎯 Outcome

Install Git on your machine and set main as the default branch name for new repositories.

✅ You Should Be Able To

  • install Git on your operating system
  • confirm that your terminal can run git
  • explain what init.defaultBranch controls

🧠 Key Ideas

  • Git is a local command-line tool. It must be installed before you can use it.
  • git init creates a new repository on your machine.
  • init.defaultBranch sets the default branch name for future repositories you initialize locally.

📥 Install Git

Choose the instructions for your operating system.

Windows

  1. Go to Git for Windows.
  2. Download the installer and complete the installation with the default settings.

macOS

Open Terminal and run:

git --version

If Git is not installed, macOS usually prompts you to install the Command Line Tools.

Linux

On Debian or Ubuntu:

sudo apt update
sudo apt install git -y

On Fedora or RHEL:

sudo dnf install git -y

🌿 Set The Default Branch Name

Run this once:

git config --global init.defaultBranch main

This affects repositories you create later with git init.

🧪 Verify

Open a new terminal session and run:

git --version
git config --global --get init.defaultBranch

🏁 Success Criteria

  • git --version prints an installed version instead of an error.
  • git config --global --get init.defaultBranch prints main.
  • You can explain that this setting affects new repositories, not every existing repository.
