How to Push Your Code on GitHub Using Terminal

Prerequisites

• Git installed on your system.

Step 1: Check Git Installation

1. Open the Command Prompt (cmd) or terminal.

2. Check if Git is installed:

   git --version
   

   If Git is installed, this command will return the version number. Now close the cmd or terminal.

Step 2: Initialize Your Project for GitHub

1. Open your project directory in cmd, VS Code terminal, or any terminal you prefer:

   cd path/to/your/project
   

2. Check if Git is already initialized in your project:

   git status
   

   If Git is not initialized, follow these steps:

   • Initialize Git:

     git init
     

   • Add all files in the folder you want to push:

     git add .
     

   If you have files or directories you do not want to push (e.g., node_modules), create a .gitignore file and specify these paths:

   echo "/node_modules" > .gitignore
   git add .gitignore
   

   • Commit the added files:

     git commit -m "Initial commit"
     

3. Create a new repository on GitHub. Copy the repository URL.

4. Add the remote repository:

   git remote add origin https://github.com/yourusername/your-repo.git
   

Step 3: Setting Up SSH for Secure Connection

1. Open Git Bash and generate an SSH key:

   ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
   

   Press Enter to accept the default file location. You will be prompted to enter a passphrase (optional).

2. Start the SSH agent:

   eval $(ssh-agent -s)
   

3. Add your SSH key to the agent:

   ssh-add ~/.ssh/id_rsa
   

4. Copy your SSH key to the clipboard:

   cat ~/.ssh/id_rsa.pub
   

   Copy the output.

5. Go to your GitHub account settings. Navigate to "SSH and GPG keys," click "New SSH key," add a title, and paste your SSH key. Click "Add SSH key."

6. Test the connection:

   ssh -T git@github.com
   

   You should see a message confirming the successful connection.

Step 4: Pushing the Code

1. Push your code to GitHub:

   git push -u origin master
   

   (If you are using a branch other than master, replace master with your branch name.)

Step 5: Pushing Subsequent Changes

1. After making changes to your project, add and commit your changes:

   git add .
   git commit -m "Describe your changes"
   

2. Push your changes:

   git push
   

Now, if you visit your GitHub repository, you should see your code.
