ftpstats.py
#! /usr/bin/env python
# Extract statistics from ftp daemon log.
# Usage:
# ftpstats [-m maxitems] [-s search] [file]
# -m maxitems: restrict number of items in "top-N" lists, default 25.
# -s string: restrict statistics to lines containing this string.
# Default file is /usr/adm/ftpd; a "-" means read standard input.
# The script must be run on the host where the ftp daemon runs.
# (At CWI this is currently buizerd.)
