Unfortunately I don't know. But what kind of "cmd" are you running?
On
http://grass.osgeo.org/wiki/GRASS_and_Python#GRASS_Python_Scripting_Library
I read
"[To be precise, they use grass.Popen(), which just calls
subprocess.Popen() with shell=True on Windows and shell=False
otherwise. On Windows, you need to use shell=True to be able to
execute scripts (including batch files); shell=False only works with
binary executables.]"

Maybe giving you some idea?

[GRASS-user] Error using grass.Popen

[António Rocha]

Greetings

I'm using grass.Popen like this:
externalProcess = grass.Popen(cmd, stdout=grass.PIPE, stderr=grass.PIPE, 
cwd=tempfile)   
It seems that I'm getting some error while running this function but the 
only thing that is printed in my command Output window is:



How can I get the exact error that I'mgetting?

Thanks

Best regards,
Antonio
