Hi

Am new to python and need your help!!

this is my code snip.
within my python script I have the following commands..

<snip>

import os
...
os.system ("cd /home; ./TestTool &")
os.system ("cd /usr/; sh run.sh load.xml &")

<snip>

I need to kill these 2 process after a particular job is done.. is
there any way to get the pids of these process and if so how do i
invoke the kill command through os.system..

or else is there anyother way to do this...
