Getting Started with Git and Version Control

1. Introduction

Tutorial's Goal

This tutorial aims to help beginners understand and effectively use Git and Version Control in their projects. We will cover the installation process and basic commands of Git, along with their practical applications.

Learning Outcomes

• Understand the basics of Git and version control
• Install Git on your local machine
• Use basic Git commands to manage and track versions of your project

Prerequisites

• Basic knowledge of command line is helpful, but not necessary
• A computer with internet access

2. Step-by-Step Guide

What is Git?

Git is a version control system that tracks changes made to files and directories. It allows multiple people to work on a project simultaneously without overwriting each other's changes.

How to install Git?

On Windows:

1. Download the Git installer from the Git website.
2. Run the installer and follow the instructions.

On Mac:

1. Open Terminal
2. Type brew install git and hit Enter (If you don't have Homebrew installed, visit Homebrew's website to install it).

On Linux:

1. Open Terminal
2. Type sudo apt-get install git and hit Enter.

Basic Git Commands

• git init: Initializes a new Git repository
• git add: Stages a change
• git commit: Saves your changes to the local repository
• git push: Pushes your local repository to the remote repository
• git pull: Updates your local repository to the latest commit
• git clone: Copies a remote repository onto your local machine

3. Code Examples

Initializing a Git Repository

To initialize a new Git repository, navigate to your project directory in the terminal and type git init.

$ git init

This command creates a new .git directory in your project, which stores all your history and version information.

Adding and committing changes

To stage changes, use the git add command followed by the file name. To stage all changes, use . (dot).

$ git add .

To commit these changes, use the git commit command with the -m option followed by your commit message.

$ git commit -m "My first commit"

4. Summary

We have covered the basics of Git and version control, installed Git, and learned how to use basic Git commands. The next step is to learn more advanced Git commands and concepts such as branching and merging.

5. Practice Exercises

1. Create a new Git repository and stage and commit a test file.
2. Clone a remote repository from GitHub to your local machine.
3. Make changes to the cloned repository and push these changes to the remote repository.

Remember, practice is key when it comes to mastering Git. Try to incorporate it into your regular coding workflow to better understand its power and utility.
