Hello world/Standard error

Hello world/Standard error
You are encouraged to solve this task according to the task description, using any language you may know.

A common practice in computing is to send error messages to a different output stream than normal text console messages. The normal messages print to what is called "standard output" or "standard out". The error messages print to "standard error". This separation can be used to redirect error messages to a different place than normal messages.

Show how to print a message to standard error by printing "Goodbye, World!" on that stream.

ALGOL 68

The procedures print and printf output to stand out, whereas put and putf can output to any open FILE, including stand error.

Works with: ALGOL 68 version Standard - no extensions to language used

Works with: ALGOL 68G version Any - tested with release mk15-0.8b.fc9.i386

Works with: ELLA ALGOL 68 version Any (with appropriate job cards) - tested with release 1.8.8d.fc9.i386 - note that printf and putf were note ported into ELLA's libraries.

main:(
  put(stand error, ("Goodbye, World!", new line))
)

Output:

Goodbye, World!

C

Unlike puts(), fputs() does not append a terminal newline. <c>#include <stdio.h>

int main() { fprintf(stderr, "Goodbye, "); fputs("World!\n", stderr);

return 0; } </c>

C#

<csharp>static class StdErr {

   static void Main(string[] args)
   {
       Console.Error.WritleLine("Goodbye, World!");
   }

}</csharp>

C++

<cpp>#include <iostream>

using std::cerr; using std::endl;

int main () {

 cerr << "Goodbye, World!" << endl;

 return 0;

}</cpp>

E

stderr.println("Goodbye, World!")

Forth

Works with: GNU Forth

outfile-id
  stderr to outfile-id
  ." Goodbye, World!" cr
to outfile-id

Haskell

import System.IO
hPutStrLn stderr "Goodbye, World!"

Java

<java>public class Err{

  public static void main(String[] args){
     System.err.println("Goodbye, World!");
  }

}</java>

Modula-3

MODULE Stderr EXPORTS Main;

IMPORT Wr, Stdio;

BEGIN
  Wr.PutText(Stdio.stderr, "Goodbye, World!\n");
END Stderr.

OCaml

<ocaml>prerr_endline "Goodbye, World!"; (* this is how you print a string with newline to stderr *) Printf.eprintf "Goodbye, World!\n"; (* this is how you would use printf with stderr *)</ocaml>

Perl

<perl>print STDERR "Goodbye, World!\n";</perl>

PHP

<php>fprintf(STDERR, "Goodbye, World!\n");</php>

Python

Works with: Python version 2.x

<python>import sys

print >> sys.stderr, "Goodbye, World!"</python>

Works with: Python version 3.x

<python>import sys

print("Goodbye, World!", file=sys.stderr)</python>

Ruby

$stderr.puts("Goodbye, World!")

UNIX Shell

echo "Goodbye, World!" > /dev/stderr
