Macro for copying SSH key to clipboard and outputting to console for those who don't support pbcopy. Add to your .bashrc or .zshrc.

sshkey.sh

sshkey () {
    local file="$HOME/.ssh/id_rsa.pub"
    if [ -n "$file" ] ; then # If the file exists.
      cat "$file"
      if pbcopy < "$file" ; then # If the text successfully copied to the clipboard.
        tput setaf 2 # Set text color to green.
        echo "SSH key copied to clipboard."
      else
        tput setaf 1 # Set text color to red.
        echo "SSH key failed to copy to clipboard but you can manually copy it above."
      fi
    else
      echo "SSH key does not exist."
    fi
}
