Git and GitHub Introduction
What is Git?
Git is a powerful tool used by developers to manage and track changes in code. It allows multiple people to work on the same project without overwriting each other’s work. Created in 2005 by Linus Torvalds, Git ensures that every change is recorded and can be reversed if needed.
How Git Works?
- Every project is stored in a repository (repo).
- Developers make changes and commit them with messages describing what was done.
- If mistakes happen, Git allows reverting to an earlier version.
- Different people can work on separate branches and later combine their work.
What Does Git Do?
- Organizes code with repositories to store project files and version history.
- Creates local copies of remote projects using cloning.
- Tracks modifications by staging and committing changes.
- Supports parallel development with branching and merging.
- Synchronizes updates by fetching the latest changes.
- Shares progress by pushing local changes to a remote repository.
Working with Git
- Set up Git in a folder to turn it into a repository.
- Git generates a hidden directory to monitor all changes.
- Any edits, additions, or deletions mark files as modified.
- Choose specific modified files to prepare for the next update.
- Save a snapshot of staged files by committing them.
- View the entire commit history to track project evolution.
- Restore a previous version if needed.
- Git efficiently records differences instead of duplicating files in every commit.
Why Choose Git?
- Trusted by the majority of developers worldwide.
- Enables seamless collaboration across different locations.
- Keeps a detailed record of all project updates.
- Allows restoring previous versions to fix errors or review changes.
What is GitHub?
- Git and GitHub are different—Git is a version control system, while GitHub is a platform built around Git.
- GitHub provides tools and services that enhance Git’s functionality.
- It is the world’s largest code hosting service, enabling developers to share and collaborate on projects.
- Microsoft acquired GitHub in 2018, further expanding its reach.
- This guide will focus on leveraging Git with GitHub for efficient development.
