# DISKPIG.PL - Reports the total bytes of each subdirectory of a directory

# This script was written by Paul Popour (ppopour@infoave.net) in 2000.

# SYNTAX - perl diskpig.pl {dirname}
#
# Example
# perl diskpig.pl C:\TEMP
# or
# perl diskpig.pl \\SERVER1\PROFILES
#
# Primary use for this script is to calculate and record the amount of
# space used by each user under their user and profile directory. You
# can also use it on the groups directory, however, it doesn't calculate
# by user only by parent directory. Will accept either a local directory
# name or a UNC share/directory. AND PLEASE - Windows 95 adds about as
# well as a two year old. If you think the script's totals are wrong feel
# free to break out the calculator.
