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.


@Nicola: Strange, running your first example made my Squeak cursor flickering until I interrupted the command ...


Best,

Christoph

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 . Try adding that to your command and see what you get.

Hello,

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
