  var  name = process.argv[2];
// argv[0] is the node install path
// argv[1] is the running file path and name

// then
console.log("hello", name);

then run node 1.js World create a helper module to handle parameters parsing

uses

var args = require("minimist")

it automatically parses parameters

var args = require("minimist")(process.argv.slice(2), {string:"name"})

we immediately pass the command line arguments (removing the first two)

so we can have var name = args.name;

then we can run:

node 1.js --name=World

we can even replace bash scripts with this

#!/usr/bin/env node

now you can chmod 700 1.js and just run $ ./1.js --name=World in the terminal, don't need to add node to the command
