[Tutor] Looking for something similar to du...

[Spencer Parker]

Mark is right...in that I don't want the actual size of the file
itself...that I can get from another way in Python which i am already
doing.  I was mainly wondering if there was a way to do it and I was just
missing something.  I looked though stat() and that is basically what I
wanted.  I wasn't sure if that was actually it until Mark spelled it out for
me.  I do love using du...since I am learning..I just wanted make sure I
wasn't missing anything...thank you guys as always...
