Hi,

Problem is that it prompts for a password. It thought i

I have a few Python programs that use popen2, and they work quite
nicely and dependably, so I don't really have any reason to change
them to use the new subprocess module...unless of course there any

Is this something I will have to plan for ?

I'm using popen2 and getting an extra 1 at the end of my output. I didn't

That's just it. I was hoping to have python listening for events and
responding continually according to the demaons stdout. That's why I

mbies, you should call the poll() or wait() method of the
Popen3 object created for each spawned process or call os.waitpid().
The problem is that the popen* functions only return the pipe objects
and not the Popen3 instance nor the process id.
Take a look at the source code of the popen2 module wh
