Two things:
First, the my_script.py is the program you want to run to get output
from. I just used a Python script as an example. This line could just as
easily be:
output, error = run_command('ls', '-l')
to list all files in a directory (though you would typically use Python's
os module for

Ross, i think i don't want to use external script, like
my_script.py ...

Yes, you can, though it's much more difficult to stream it live to a web

this, but it's not the simplest thing in the world.

There is another HTML5 technology to push stream from server to client :
EventSource aka Sent-Server Events (http://dev.w3.org/html5/eventsource/).
Its behaviour is like ajax long polling.
I'm - just now - experimenting a simple mechanism to send to clients a
message when the database changes.
Thank's Alan
that was very inspiring for noob like me..
if we look at

,can we use similar methods to do real time streaming output ??

Thank's massimo..
look's very complex to do..
Massimo, is there web2py feature's for doing this ?

I use subprocess.Popen a lot to run shell commands from Python. There is no
need for a specific web2py feature.
This is the method I use whenever I need to call something:
import subprocess
def run_command(self, *args):
Returns the output of a command as a tuple
Okey Ross, if we using popen, can we doing it for real time (i mean,
streaming output) ?

I am not sure if web2py has a feature for that. You can still redirect
output to a filelike object during controller processing and on exit
return the control to the original handler. That way you could extract
the output from the file object to append it to the web2py response
Pseudo-code:

There are two ways around it:
- hopefully the apt module can be configured to send output to a file
- if not, use the python subprocess module to run the code is a
separate process. The popen function has the ability to capture the
output.
