[tlug] Using TCT...help

[Operator <gauin_36@example.com>]

Tlug'ers and Experts,

My question is based on a question from a book that was suggested to me by 
many admin's "Its called "Linux Adminsitration Handbook" by Evi Nemeth, Garth 
Snyder and Trent R.Hein. I've finished chapter 2 and now its exercise time. 
Most of the exercises in this chapter were simple until this one came up..  
<snip for the book>  using mactime..

Run mactime to create an initial database of the time stamps associated with 
your system files. (done) Re-boot your machine (done) Run mactime again and 
determine which files have been modified by booting the machine. Which files 
were accessed but not modified? (Requires root access.)

My problem (question) is how do I determine which files have been modified?? 
I'm not sure but I THINK the diff command is used here... again.. not sure.. 
Because of this book, I'm really starting to feel like a Sys Admin.. not 
somebody who has 8 computers online just to surf and get e-mail!!  I'm using 
Linux in a nutshell to check my command usage but still not sure.. please 
advise.. thanks for your help and May the Lord keep your systems up and files 
in check!

Sincerely,
Gavin
