    Runs the given command and sends a pushbullet notification if the exit status is non-zero.

    The message can be customized, and there are a few values that you can use through placeholders, eg:
      The command %{command} returned %{status}: %{result}

    Available keys for the message:
     - command
     - status
     - result
  DESC
  option :message, default: "The command %{command} returned %{status}!\n%{result}"
  option :title, default: "Notifatron"
  option :key, default: ENV['PUSHBULLET_KEY']
  def pushbullet command
    if options[:key].nil?
      raise ArgumentError.new("Need to specify the pushbullet key in the environment as PUSHBULLET_KEY")
    end

    pushbullet_client = Washbullet::Client.new(options[:key])

    res = {
      command: command,
      result: system(command),
      status: $?.exitstatus
    }

    if res[:status] != 0
      message = options[:message] % res
      #puts "Would push notification: #{ options[:title] } - #{ message }"
      pushbullet_client.push_note nil, options[:title], message
