Installing Git & First-Time Git Setup

Goal

Install Git on Ubuntu 24.04 and configure your identity and defaults.

Install Git (Ubuntu 24.04)

sudo apt update
sudo apt install -y git
git --version

Configure Identity (Required)

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

Recommended Defaults

# Default branch name for new repos
git config --global init.defaultBranch main

# Safer line endings for cross-platform projects
git config --global core.autocrlf input

# Colorized output
git config --global color.ui auto

# Preferred editor (choose one you use)
git config --global core.editor nano
# git config --global core.editor "code --wait"
# git config --global core.editor vim

Verify Configuration

git config --global --list
cat ~/.gitconfig

Outcome

Git is installed and your global identity and defaults are set.
