This simple script calls out to find (on a Mac). For me this

I found a workaround with pipeProcess.

    auto pipes = pipeProcess(spec, Redirect.stdout | 
Redirect.stderr);

    scope(exit) {
      auto exitCode = wait(pipes.pid);
      if(exitCode) {
        writeln("*** Exited rc(", exitCode, ")");
      }
    }

    foreach (line; pipes.stdout.byLine) writeln(line);

    foreach (line; pipes.stderr.byLine)
      writeln(text("STDERR| ", line.idup));
  }

Thanks,
Dan
