@Nicola: Strange, running your first example made my Squeak cursor flickering until I interrupted the command ...
Double check: ------- p := PipeableOSProcess command: 'ls -la'. p output. -------
1] In MacOS 10.14.5, confirmed to work. 2] In FreeBSD 12 (Linux emulation 64bit) , confirmed to work
Can't tell you much more unfortunately.

Hi John,
[(OSProcess command: 'notepad.exe 2>&1') value] passes '>2&1' as an argument to notepad.exe. If I use PipeableOSProces instead, there is only shown an empty cmd window, no matter what the command is.

Christoph,
You are more fortunate than I am. I tried it on my Win 7 box and it caused a crash.
There is a way to send output to stdout and stderr https://support.microsoft.com/en-us/help/110930/redirecting-error-messages-from-command-prompt-stderr-stdout . Try adding that to your command and see what you get.

I am trying to run a simple shell command using OSProcess:
ExternalWindowsOSProcess command: 'taskmgr.exe'
I'm afraid it "does not work", so after evaluating this expression, no window opens and also no icon appears in the systray. If I open cmd.exe and type taskmgr.exe there, taskmgr opens.
However, the following works as expected:
ExternalWindowsOSProcess command: 'notepad.exe'
Using absolute paths did not change the behavior.
I installed the latest OSProcess version via SqueakMap. Is this a bug, or is it me? Thanks in advance!
Christoph
