it helps some times learnyounode run filename.js runs node filename.js {{fileToBeRead}} which is to say you need to give it a command line argument or process.argv[2] will be undefined which is causing fs.readFile(undefined, . . . to throw an error.

fixed the issue. Will look into that further You can parse a string in the same way bash does by using a shellwords port. There is a javascript version of ruby's shellwords module called shellwords on npm (https://github.com/jimmycuadra/shellwords).
npm install shellwords
code :
var shellwords = require('shellwords');
shellwords.split("foo 'bar baz'");
// ["foo", "bar baz"]

should help you out string a[] = {"1","2"} is a 2-element array. There will be no hidden NULL-pointer appended to it. Accessing a[2] (the would-be 3-rd element of it) renders your program undefined. There's not much of a point in analyzing how different variables affect a program whose behavior is undefined. It can vary from compiler to compiler.
code :
#include <stdio.h>
int main(void)
    //arrays of char initialized with a string literal end with '\0' because
    //the string literal does
    char const s0[] = "12";
#define NELEMS(Array) (sizeof(Array)/sizeof(*(Array)))
    printf("%zd\n", NELEMS(s0)); //prints 3

    //explicitly initialized char arrays don't silently append anything
    char const s1[] = {'1','2'};
    printf("%zd\n", NELEMS(s1)); //prints 2

    //and neither do array initializations for any other type
    char const* a[] = {"1","2"};
    printf("%zd\n", NELEMS(a)); //prints 2
