Git and GitHub Introduction

What is Git?

Git is a popular version control system. It was created by Linus Torvalds in 2005, and has been maintained by Junio Hamano since then.

It is used for:

  • Tracking code changes
  • Tracking who made changes
  • Coding collaboration

What does Git do?

  • Manage projects with Repositories
  • Clone a project to work on a local copy
  • Control and track changes with Staging and Committing
  • Branch and Merge to allow for work on different parts and versions of a project
  • Pull the latest version of the project to a local copy
  • Push local updates to the main project

Working with Git

  • Initialize Git on a folder, making it a Repository
  • Git now creates a hidden folder to keep track of changes in that folder
  • When a file is changed, added or deleted, it is considered modified
  • You select the modified files you want to Stage
  • The Staged files are Committed, which prompts Git to store a permanent snapshot of the files
  • Git allows you to see the full history of every commit.
  • You can revert to any previous commit.
  • Git does not store a separate copy of every file in every commit, but keeps track of changes made in each commit!

Why Git?

  • Over 70% of developers use Git!
  • Developers can work together from anywhere in the world.
  • Developers can see the full history of the project.
  • Developers can revert to earlier versions of a project.
