[Help-smalltalk] Getting the output of a system command

My intention is to write the output of a command I execute inside my
application, into a graphical widget. But first I have to get the output
from execution. When I execute a command like this:

Smalltalk system: 'bla bla bla'

it returns the exit code. When I execute a command via opening a pipe:

pipe := FileStream popen: 'bla bla bla' dir: FileStream read.

I can get the "normal" output by #nextLine etc. But if it exits with an exit
code different then 0, I cannot read any output, for example, #nextLine
returns nil. How can I get the error message as well?
