var fs = require('fs');
var Executor = require('node_executor');

const args = process.argv.slice(2);

const cmd = args[0];
const param = args.slice(1);

x = new Executor(cmd, param);

x.chop(function(v) {
  fs.appendFile('./test.log', v, function () {
    console.log(`appended to ${v} to file`):
  });
});
