[NTLUG:Discuss] Re: Is there a command line utility which will report directory statistics?

[Kenneth Loafman]

What the Evil Empire does is give you a summation of how much space the

command gives you the actual amount of space the files occupy, including 
cluster tips.  From an admin standpoint, that is much more useful.
