std.process spawnShell/pipeShell dont capture output of the shell

[Geert via Digitalmars-d-learn]

I'm sorry for the "necro-bumping", but I've not found the 
solution for this yet, and i'm getting a different error message 
at the execution moment:

"std.stdio.StdioException@/build/ldc/src/ldc/runtime/phobos/std/stdio.d(4066): Bad file descriptor"


This is my testing code:



module dd_test;

import std.stdio, core.stdc.stdlib;
import std.process, std.string;

int main(string[] args) {

     string command_find = "(find /usr/share/icons/ -name a*) ";
     //string command_dd = "(dd if=/dev/urandom | pv -ptrbef -i 2 
-s 2339876653 | dd of=/dev/null) 2>&1";

     auto p = pipeShell(command_find, Redirect.all);

     foreach(str; p.stdin.byLine){
         writefln("IN: %s", str);
     }

     foreach(str; p.stdout.byLine){
         writefln("OUT: %s", str);
     }

     foreach(str; p.stderr.byLine){
         writefln("Error: %s", str);
     }

     return 0;
}
