Git is a powerful distributed version control system widely used by developers to track changes, collaborate effectively, and maintain a comprehensive history of projects. Whether you're a beginner or looking to deepen your understanding, this guide covers everything you need to know about Git basics. Git is a free and open-source tool designed to handle everything from small to very large projects with speed and efficiency. It allows developers to: Creates a new Git repository in your project directory. Copies a remote repository to your local machine.

Displays the current state of your repository, including staged, unstaged, and untracked files. Git and GitHub have become essential tools in the modern developer’s toolkit, facilitating version control, collaboration, and efficient project management. Whether you are a novice or an experienced developer, mastering these tools can significantly enhance your productivity and ability to work in a team. This comprehensive guide will walk you through the essentials of Git and GitHub, from basic concepts to advanced workflows. Git is a distributed version control system (DVCS) that allows developers to track changes, revert to previous states, and manage collaborative workflows. Created by Linus Torvalds in 2005, Git is designed for speed, efficiency, and data integrity.

To get started, install Git on your machine: After installation, configure Git with your name and email, which will be used in commits: Use the log command to view commit history: Comprehensive structured learning path with 6 progressive modules, real-world use cases, and step-by-step workflows. Perfect for systematic learning from beginner to advanced. Quick reference format with focused sections on specific topics.

Great for quick lookups and targeted learning. Welcome to the Git Guide that takes you from a beginner to an advanced user! This repository is organized into four main sections: The Beginner Guide is designed to help new users understand and use Git with practical examples. The Advanced Guide covers more complex Git topics for users who are already familiar with the basics. Master Git, GitHub, and Version Control.

Learn Git installation, branching, merging, GitHub collaboration, and advanced techniques. Ideal for developers, DevOps engineers, and anyone eager to learn version control with Git and GitHub. Basic programming knowledge is helpful. Ideal for developers, DevOps engineers, and anyone eager to learn version control with Git and GitHub. Basic programming knowledge is helpful. Set up and configure Git on Windows, macOS, and Linux.

Manage repositories, branches, and commits effectively. In this walkthrough, I am going to show you the most basic Git commands that you need to know. I am assuming you already have Git installed on your system. If you do not, I have installation videos for both Mac and Windows - go check those out first. Otherwise, let us go ahead and get right on into it. I am on a Mac and I am going to open up a Terminal window.

If you are on Windows, you can open up Command Prompt or PowerShell - both will work for what we are doing. The plan is simple and very real world. I am going to go to my Desktop, create a brand new folder called fruit, and we are going to store our code in there while we learn Git. I am going to cd into that fruit directory. I am also going to open it up in a Finder window so we can keep an eye on what we are doing visually. When I say I am keeping an eye on it, imagine Finder sitting next to Terminal, and every time I create or change a file, you will see it appear or change in Finder.

That way you can connect what Git is saying in the terminal with what is actually happening on your file system. On Windows, open File Explorer to the folder you are working in so you can watch files appear as you create them. Use Command Prompt or PowerShell to run the same commands shown here. The commands are identical unless you are doing something very shell specific, which we are not. One of the most often overlooked setup steps in Git is the Git config file. Basically, when you make commits to a Git repository, we want to know who made that commit - that it is you and not somebody else.

Git records the author on each commit, and if you do not tell Git who you are, it will ask, or worse, you will end up with commits with missing or incorrect identity. If you're just beginning programming, you've likely encountered the name "Git"—but what is it? And why do you need it? Git is the most important tool I use, next to my text editor, operating system, and laptop. I'm using it right now. It tracks every change I make to my articles and code.

While basic Git skills are easily attainable for beginners, it possesses many features which make it seem complex. In this article, I'll reveal why Git is crucial and why you should start using it today. Basically, Git is a version control system that tracks changes in text-based files. Each version represents a significant change to your documents. People typically use Git for tracking source code, but you can use it to track any text files. But what do I mean by "text document tracker"?

It records changes to a text document in a way that makes reverting them possible. A perfect analogy is a piece of paper (a text document) with a sheet of glass placed on top. Picture writing a few sentences on it with a magic marker. Once complete, place another sheet on top, and repeat the process—forming a paragraph. Looking down onto the layered glass, you'll see a complete paragraph. For each sheet you remove, you will undo changes.

That is how Git works: it tracks each change, allowing you to undo them if desired. To make Git track the documents in a directory, you must first execute git init within it. Git then creates a repository by populating a local .git directory with tracking information. The .git directory contains binary files. These files act like the previously mentioned sheets of glass. They track different checkpoints—aka commits.

Git uses them to go forward or back through the repository's history. Master Git fundamentals and advanced concepts with this comprehensive guide. Learn essential commands, practical workflows, and best practices to streamline your development process and ace your next technical interview. Start learning today! Git, the open-source distributed version control system, is a cornerstone of modern software development. This guide provides a solid foundation in Git basics, essential for both beginners and those preparing for technical interviews.

Before we begin, let's verify that Git is installed and check its version. If you don't have Git installed, you'll need to install it using your system's package manager. The following commands illustrate how to do this using apt (Debian/Ubuntu) and check the version. Let's walk through a typical Git workflow. Imagine you're working on a new feature. Here's how you might use Git:

Here's how these steps might look in the terminal:
