Using Command Line Arguments in Node

server.js

//Simple commands: type in console server -f/-g

var units = process.argv[2];
if(units == '-f'){
    this.setUnits('Fahrenheit');
} else {
    this.setUnits('Celsius');
}

//Flag and Argument Pairs: type in console node -c Tampa,FL 
var city;
if(process.argv.indexOf("-c") != -1){ //does our flag exist?
    city = process.argv[process.argv.indexOf("-c") + 1]; //grab the next item
}
