Git and GitHub Commands Guide

This guide includes essential Git and GitHub commands that are commonly used in version control and collaborative development.

1. Install Git

Download and install Git. During installation, accept the default settings unless you have specific preferences.

2. Configure Git (First Time Setup)

Set up Git

Open your terminal or command prompt and configure your user information for Git using the following commands:

git config --global user.name "Your Name"
git config --global user.email "your-email@example.com"

3. Create a Local Repository

Navigate to the directory where your project is located and initialize it as a Git repository (if not already done):

git init

4. Add Files to the Repository

Add your project files to the repository. You can add individual files using:

git add filename

Or add all files in the directory with:

git add .

5. Commit the Files

Commit your added files to your local repository:

git commit -m "Initial commit"

Replace "Initial commit" with a meaningful message describing what you are committing.

6. Create a Repository on GitHub

(i) Go to GitHub and sign in.
(ii) Click the "+" icon in the top right corner and select "New repository."
(iii) Name your repository, add a description (optional), and choose whether it's public or private.
(iv) Click "Create repository."

7. Link Your Local Repository to GitHub

Copy the URL of your newly created GitHub repository. Then, link your local repository to GitHub with:

git remote add origin <REPOSITORY_URL>

Replace <REPOSITORY_URL> with the URL of your GitHub repository.

8. Push Your Code to GitHub

Finally, push your code to GitHub with:

git push -u origin main

9. Subsequent Pushes

For any subsequent pushes after the initial push, you can simply use:

git push

These steps cover the basics of pushing code from a local repository to a GitHub repository.
