Configs

Git-GitHub

Install git

Git usually comes pre-installed with most Linux distros, but you if not in yours, you can install it via you package manager (apt, dnf etc) as instructed on Git download page:

# For Fedora:
sudo dnf install git

Set name and email

Referring the First-Time Git Setup page:

• To set name and email across all your repos, set it in global Git config as:

  git config --global user.name "John Doe"
  git config --global user.email "john.doe@example.com"
  

• To verify, you can view your global git config as: git config list --global. Your global git config is stored in ~/.gitconfig file

You can also refer my git config

GitHub SSH setup

• Generate new key pair (passing parameters: type -t and comment -C):

  # You will be prompted for the key's storage location and passphrase
  ssh-keygen -t ed25519 -C "john.doe@example.com"
  

  Your keys would be saved in the ~/.ssh/ folder and the pair would be named like:

  • keyname for private key
  • keyname.pub for the public key

  You can notice it in the output or previous command as:

  Your identification has been saved in /home/kumar/.ssh/id_ed25519
  Your public key has been saved in /home/kumar/.ssh/id_ed25519.pub
  

• Start ssh-agent in the background:

  eval "$(ssh-agent -s)"
  

• Add your SSH private key to the ssh-agent:

  ssh-add ~/.ssh/id_ed25519
  

• View your SSH public key and copy the output contents

  cat ~/.ssh/id_ed25519.pub
  

• Log into your GitHub account. Go to Settings > SSH and GPG keys. Click New SSH key. Give it a title and paste the previous noted output into the Key textarea box. Finally click Add SSH key

• Test if the SSH connection method works:

  ssh -vT git@github.com
  

  In the output:

  ...
  Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
  ...
  Hi datkumar! You've successfully authenticated, but GitHub does not provide shell access.
  

Also try cloning any GitHub repo via the SSH method url: git@github.com:USERNAME/REPONAME.git
