starting and stopping a program from inside a python script

[dfaber]

Aloha!
I want to terminate a process/program from within a python script.

For example,
if I have a program say foo.sh that starts running, then I can run it
from within a python script using
os.popen('foo.sh') which starts a program/process say 'bar'

At some point later, I want to kill 'bar'. Currently, I start off the
process and then when the python script exits, the process 'bar' is
still running and I have to issue ps -ef | grep 'bar' and then kill
it.

Is there any better way of doing this?

You can store the pid of the process when started and later use it to kill it.

cheers,
