Getting Setup with Git

My procedure for getting up and running with git

1. Install Git: Open a terminal and type in the following command:

    sudo apt install git
   

   Verify the installation with:

    git --version
   

   This should show the installed Git version.

2. Set up Git: Configure your email and username for Git, replace “you@example.com” and “your-username” with your email and username respectively:

    git config --global user.email "you@example.com"
    git config --global user.name "your-username"
   

3. Generate a new SSH key: To clone private repositories, you need to authenticate with GitHub. One of the ways to do it is by using SSH keys. Here’s how you can generate a new SSH key:

    ssh-keygen -t ed25519 -C "you@example.com"
   

   Follow the prompts and press Enter to accept the default location and to use an empty passphrase. You can also use a passphrase if you’d like to.

4. Add the SSH key to the ssh-agent: Start the ssh-agent in the background:

    eval "$(ssh-agent -s)"
   

   Add your SSH private key to the ssh-agent:

    ssh-add ~/.ssh/id_ed25519
   

5. Add the SSH key to your GitHub account:

   • Copy the SSH public key to your clipboard:

       cat ~/.ssh/id_ed25519.pub
     

   • Go to GitHub, click on your avatar in the top right corner and go to ‘Settings’.
   • In the user settings sidebar, click on ‘SSH and GPG keys’.
   • Click on ‘New SSH key’, provide a title, paste your key into the ‘Key’ field and click ‘Add SSH key’.

6. Clone the repository: Now you can clone the private repository. Replace ‘user’ and ‘repo’ with the username and the repository name:

    git clone git@github.com:user/repo.git
