Well, I have to take back the comment on command:. I have this code snippet that gets output from a command:

| p d ��|

p := (PipeableOSProcess command: 'netstat -a | grep LISTEN | grep ��27017').

p keepInitialStdOutOpen: true.

d := Delay forMilliseconds: 500.

d wait.

[Transcript show: (p next: 300); flush. p isComplete] whileFalse: [d wait].

Transcript show: 'Error output';

p closeOutput.

Still experience the same problem, is this suppose to be fixed with new OSProcess ?
