require 'optparse'

  opts.on('-h', '--help', 'Displays Help') do

parser.parse!

restart_count = 0

while true
  `lt --port #{options[:port]} --subdomain #{options[:subdomain]}`
  restart_count += 1
  puts "times restarted: #{restart_count}"
end

put it in your path somewhere and run chmod +x localtunnel
