Sending commands over serial without IDE?

Hi,
I would like to send commands over to my espruino via serial.
I think this is the way:

echo 'digitalWrite(LED1, 1) < /dev/tty.usbmodem1421

However, it doesn't do anything. My terminal shows me no feedback whatsoever, even if I press enter or ctrl+c.
Am I doing something wrong?
I have to do it over serial; I can't have my board connected with a prompt always on because I have this home automation project for my dorm and I would like to send serial commands wirelessly with bluetooth, and the espruino's going to be stuck somewhere on the wall.

Thanks!

Something like that should work, but you do have a missing end quote in that code and the wrong arrow...

I just tried:

echo "LED1.reset()" > /dev/ttyACM0 

and that works great on Linux (and should do on mac if you change the /dev/tty... path.

And one more thing - there is a command-line app to do some other simple things for you too: https://www.npmjs.com/package/espruino

But if all you want to do is send commands, the echo is probably best :)
