This didn't work for me...
I thought it might be my program so I wrote the following simple
program to test it.

#include <iostream>
#include <fstream>

/* arg_test.cpp */

using namespace std;

int main(int argc, char *argv[])
{
  for(int val=0; val<=argc; val++)
    cout << argv[val] << endl;

  return 0;
}

This ("./arg_test bob carol ted alice") generates:
./arg_test
bob
carol
ted
alice

However this (ls /home/mark/programs/cpp | ./arg_test) only generates:
./arg_test

Any suggestions?

Thanks,
Mark.
