How to run functions from Command Line in Node module

Question

Lets say I have this node module in a file called runJS.js:

var someObject = {
    "getName": function(name){
        return name;
    }
}

exports.defult = someObject;

I know you can run the file at the command-line doing node runJS.js but how do say hey, I want to run getName from the command-line through the node command?

You would have to build that logic into your program, reading any passed in arguments and acting upon them. — user400654

Node.js accepts a "-e" option

-e, --eval script     evaluate script

So you can try something like

node -e "require('./runJS').getName()"
