Git How To: Setup a Linux PC to access GitHub via SSH

Steps

# Go home on your Linux machine
$ cd ~

# Check for existence of .ssh directory
$ ls -al .ssh

# Generate an ssh key for GitHub – creates .ssh dir if it doesn't exist
$ ssh-keygen -t ed25519 -C some_email@test.com

# Run the ssh agent for "single sign on"
$ eval "$(ssh-agent -s)"

# Add the private key and pass phrase to the ssh agent
$ ssh-add id_ed25519

# Copy public key to clipboard, paste into GitHub via Settings
$ xclip -selection clipboard < id_ed25519.pub

# List .ssh directory
$ ls /home/your_user_name/.ssh/

# Test connection to GitHub using your ssh key (prompts for passphrase)
$ ssh -T git@github.com

# Start cloning
$ git clone git@github.com:your_github_user/your_repo1.git
$ git clone git@github.com:your_github_user/your_repo2.git
