UNIX Utilities: Echo

This is the first post of what I hope to be many describing UNIX command line utilities, first up is the "echo" command:

/**
 * A copy of the "echo" command on UNIX, missing a few options, but it
 * does what is normally asked of it.

#include <iostream>

using namespace std;

int main(int nargs, char* vargs[])
{
 for(int i = 0; i < nargs - 1; i++)
 {
  if(i != 0)
   cout << " ";
  cout << vargs[i + 1];
 }
 cout << "\n";
}
