in reply to Pipe Question

Two notes:
  1. Your pipe is on the wrong side. It should be:
    open(P,'./|'); while (<P>) { print; $count++; } close(P); print "$count\n";
    which gives you what you expect.
  2. Make sure your scripts are mode +x! If you can't run them from the command line, they won't work.
In general, though, remember - put the pipe on the side as you would if you ran them on the command line; that is: ./ | ./ would be what you'd run in this case, so use the pipe after the script name. (If you wanted to write to it, you'd put the pipe before.)
