Python Subprocess module

[Dave Sampson]

Thanks for your response. It;s good to see you're promtoing Pexpect. I
was actualy wokring on a project at work that could have used Pexpect
to automate the creation of maps by tieing togethr a bunch of
processes through SSH and Pexpect looked like the money shot.

however it was enough of a battle to bring Python into the game since
it is government that bringing CYGWIN was a battle not worth
fighting.  Which is unfortunate because I think Pexpect was exactly
what we needed in that case

I obviously lack skills and understanding in many aspects of
programming. After all I'm a geographer / recreologist not a comp-sci
professional.

I understand the CONCEPT of pipes but don't know how to use or
implement.. the bigest things I ever do is something like

dmesg | grep wlan0

Where | is my pipe... but that is the extent of my knowledge and
skill.

Pexpect may very well be the option I need, and having a project that
supports the module is great. I am curous what is stopping Pexpect
from becoming cross platform.

Above, a user suggested implementing send keys in windows. Why not
include that as an try/except in Pexpect instead of my wrapper?  That
way it can benifit many more people?

Cheers
