Hi I'm on my phone but I will try to guide you as I can. I will clarify when near a computer if needed

What I think you want is to read the stdout from a spawn and do something with the data?

You can give the spawn a variable name instead of just running the function, e.g:

var child = spawn();

Then listen to the output like:

child.stdout.on('data', function(data) {
    console.log(data.toString());
});

You could use that to write the data then to a file or whatever you may want to do with it.
