Git is a distributed version control system designed to handle everything from small to very large projects with speed and efficiency. Created by Linus Torvalds in 2005, Git allows multiple developers to work on a project simultaneously without overwriting each other’s changes, making it an essential tool for collaborative software development.

Setting Up git²

Update the System

sudo apt update
sudo apt upgrade

Set up a Git username:

git config --global user.name ""

To confirm that you have set the username correctly,

git config --global user.name

The enclosing quotations marks are empty intentionally. You should type your username in between.

Set an email address:

git config --global user.email ""

To confirm that you have set the email address correctly,

git config --global user.email

If you opted to use the private GitHub email address, you can use a GitHub-provided noreply email address³. Then use this command instead,

git config --global user.email "id+username@users.noreply.github.com"

Configuring git

To change the default branch for git,

git config --global init.defaultBranch main

To enable colorful output with git,

git config --global color.ui auto

To set the default branch reconciliation behavior to merging,

git config --global pull.rebase false
