Git by Nouman - Shell-Bash

Introduction

Welcome to Git by Nouman - Shell-Bash! This tutorial is designed to introduce you to Git and its basic commands. Git is a version control system that helps you track changes in your code over time, collaborate with others, and maintain different versions of your project.

Why Git?

Git is widely used in the software development industry, and is a highly praised tool. Here are a few reasons why:

• It allows you to share your code with others more easily.
• You can work on multiple versions of your code at the same time.
• You can save changes made to your code easily, without overwriting previous work.
• Git has a built-in merge conflict resolution tool, which helps to simplify collaboration between multiple contributors.
• It supports branching, which allows you to create branches of your code and work on them independently of other branches.

Getting Started

Firstly, you need to install Git on your computer. The easiest way to do so is to go to the download page and download the version of Git that is compatible with your operating system.

To check if Git is installed on your computer, open a terminal (Unix-based) or Git Bash (Windows). Type git --version and press enter. If Git is installed correctly, you'll see a message that displays the version of Git that is installed.

Basic Git Commands

Here are some of the basic Git commands that you'll be using frequently:

git init

The git init command initializes an empty Git repository in your current directory. Once you run this command, you'll see a folder named .git which contains all the files necessary for Git to work.

git add

To add files to your Git repository, use the git add command. For example, if you want to add a file called index.html, you would run git add index.html.

git commit

Once you've added your files to your Git repository, you need to commit the changes. To do this, use the git commit command. For example, if you want to commit your changes with a message that says Added index.html file, you would run git commit -m "Added index.html file".

git clone

If you want to clone a Git repository from a remote source, use the git clone command. For example, if you want to clone a repository from GitHub, you would run git clone https://github.com/username/repo.git.

git push

Once you've made changes to your code and committed them, you can use the git push command to push your changes to a remote repository. For example, if you want to push your changes to the master branch, you would run git push origin master.

git pull

If you have changes in a remote repository that you want to pull to your local repository, use the git pull command. For example, if you want to pull changes from the master branch, you would run git pull origin master.

Conclusion

This tutorial has covered some of the basic Git commands that you'll need to know as a programmer. As you become more comfortable with Git, you'll start to use more advanced features such as branching and merging. If you need more information about Git, the official Git documentation is a great resource.
