Okay, sorry for the delay to the response. I got side tracked trying
to stalk, I mean talk to the 59 year old neighbor girl. Anyways, I
couldn't get it to one in one line. Here is what I did...

% more rec.py
#!/usr/local/bin/python

import os
import time

for filename in os.listdir("/usr/bbs/confs/september"):
     #stat = os.stat(filename)
     if filename.startswith("_"):
        print filename

./rec.py
_1
_2
_3
_4
_5
_6
_7
_8

It correctly prints out all the files in the directory that start with
an underscore.
