Output for javascript program is 'undefined' when trying to run in command line

wish helps you You have a few issues with your code:
The console.log() after your return will not run, as any code after a return will not be executed as the function is no longer running.
code :
for(var i = 0; i < A.length; i++) {
  // Do code
var sortArrayByParity = function(A) {
  E = [];
  O = [];
  for (var i = 0; i < A.length; i++) {
    if (A[i] % 2 === 0) {
    } else {
  return E.concat(O);

var res = sortArrayByParity([1, 2, 3, 4]);  
console.log(res); // [2, 4, 1, 3] (sorted by evens first, odds second)

Different output -- when running mathtext in command line and when the command is executed from a java program using apa

Any of those help I figured out where the problem was:
$ is a special character for the unix shell and not for java. So even if in the command line the input needs to escape $ like:
code :
"\$\frac{{\left( {{p^2} - {q^2}} \right)}}{2}\$"
$\frac{{\left( {{p^2} - {q^2}} \right)}}{2}$

I wish this helpful for you You're not stopping your thread pool, so it's not letting your main program end.
Consider the following code:
code :
import java.util.concurrent.Executors;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.atomic.AtomicInteger;

class Worker implements Runnable {
    private AtomicInteger i;
    private Object lock;
    private int max;
    private int mod;

    Worker(AtomicInteger i_, Object lock_, int max_, int mod_){ 
        this.i   = i_;
        this.lock = lock_;
        this.max  = max_;
        this.mod  = mod_; 

    public void run(){
        while (i.get() < max)
            if(i.get() % 2 == mod)
                System.out.print(" " + i.getAndAdd(1));

                synchronized(lock){ lock.notify(); }
                    try { lock.wait(); }
                    catch (InterruptedException e) { e.printStackTrace(); }

public class NumPrintTX
   public static void main(String[] args)
        final int max = 31;
        final AtomicInteger i = new AtomicInteger(0);
        ExecutorService dd = Executors.newFixedThreadPool(2);

        final Object lock = new Object();

        dd.execute(new Worker(i, lock, max, 0));
        dd.execute(new Worker(i, lock, max, 1));


Linux how to pass date command's output as input for a python program as command line argument

I wish this help you If you want to pass the output of date to python you can pipe it (using |) or you can pass it as a command line argument.
Consider the following python program:
code :
import sys

print "Command line input:"
print sys.argv;

print ""

print "Standard input:"
print sys.stdin.read()
echo "hmm, this is text" | python test3.py "`date`"
Command line input:
['test3.py', 'Mon  9 Feb 21:10:00 AEST 2015']

Standard input:
hmm, this is text
date | python test3.py

Java getting output from program executed in command line when it constantly updates a single line in the command prompt

By : robert.downy

wish of those help I think I see what's going on. readLine() is looking for a '\n' character. Single-line programs emit a '\r' to return to the beginning of the line and re-write it over and over.
I read around commons-io and javadocs and neither of them have a readLine(char c) which would read until a particular character is encountered, so unfortunately I think you have to code this up for yourself. :\
