This works on my linux box and as Joe was looking for
'ls -l', I assume it'll work for him too.
But as I hadn't used the commands module before, I tried it
on both my Win95 and Win2k boxes, where it failed to get the
right info. So, either I'm doing it wrong, or the
combination of commands and windows is broken, which I
suspect.
However, a=os.popen("dir").readlines() works on windows and
linux. So if you're writing cross-platform, you'll want to
keep this in mind.
