Setting-Up-Git-with-GitHub

Git and GitHub are essential tools for modern developers, providing robust version control and collaboration features. If you’re using a Linux system, here’s a comprehensive guide to get you started.

Prerequisites

• A Linux machine (Ubuntu, Fedora, etc.)
• A GitHub account (sign up at github.com)

Step 1: Install Git

First, you’ll need to install Git on your Linux machine. Open your terminal and execute the following command based on your Linux distribution.

For Debian-based distributions (e.g., Ubuntu):

sudo apt update & sudo apt install git

For RPM-based distributions (e.g., Fedora):

sudo dnf update & sudo dnf install git

To verify the installation, run:

git --version

Step 2: Configure Git

After installing Git, you need to set up your username and email address. These details will be included in your commit messages.

bash

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

To confirm your configuration, use:

bash

git config --list

Step 3: Generate SSH Key

For secure communication with GitHub, it’s recommended to use SSH. Generate an SSH key pair using the following command:

bash

ssh-keygen -t ed25519 -C "your.email@example.com"

Press Enter to accept the default file location, and then enter a passphrase for added security.

Step 4: Add SSH Key to GitHub

Copy your public SSH key to your clipboard:

bash

cat ~/.ssh/id_ed25519.pub

Log in to your GitHub account, go to Settings > SSH and GPG keys, and click New SSH key. Paste the copied key and give it a title.

Step 5: Test the SSH Connection

Test your connection to GitHub with:

bash

ssh -T git@github.com

You should see a message like:

Hi <username>! You've successfully authenticated, but GitHub does not provide shell access.

Step 6: Create a Repository

Now, you can create a new repository on GitHub. Click the New repository button on your GitHub dashboard, name your repository, and click Create repository.

Step 7: Initialize a Local Repository

Back on your Linux terminal, navigate to your project directory and initialize a local Git repository:

bash

cd /path/to/your/project
git init

Step 8: Add Remote Repository

Link your local repository to the GitHub repository:

bash

git remote add origin git@github.com:<username>/<repository>.git

Step 9: Add and Commit Files

Add your project files and commit them to your local repository:

bash

git add .
git commit -m "Initial commit"

Step 10: Push to GitHub

Finally, push your local commits to the GitHub repository:

bash

git push -u origin main

And there you go! You’ve set up Git with GitHub on your Linux system. Happy coding!
