running windows 'start' cmd using spawnl

[Tor Erik]

Hi,

I need to start a program in a new cmd-window. To do this I need to
execute: start [command]
With os.system this is straight-forward.
But I need to do it with spawnl and P_NOWAIT. I.e, asynchronously.
The problem is that I need to know the path where start resides,
which I'm unable to find.

Does anyone know where this command is located, or an alternative way of
doing what I want?

regards

On Windows NT, XP, 2003 and others, there is no "start.exe"
executable; it's an internal command. It only exists on 95, 98, maybe ME.
Try the subprocess module.

os.startfile(command) could work.

Hi!

You can use (exemple) :

"cmd /cSTART notepad"
