parsing a file [newbie]

[Langa Kentane]

ONe thing I don't understand.
When I run os.popen('df -h'), this returns a pointer to an already open file
if I am not mistaken.

Now, to apply what you gave me to this scenario, how would I go about it.  I
am confusing myself silly here.

Please help.

import os
my_command = "/whatever/you/like"
open ("output", "w").write (os.popen (my_command).read())
y = open ("output").read().split() [2]

Hope this works, I haven't tried it. This is quick and dirty though, better
implement some error checking.
