I'm not concerned about a file having been changed, just whether % cp -rp /home/klinebak/foodir /home/kline/ is 100% reliable. down to the bit! a friend has volunteered to take over my system admin chores. he left my drive fragmented and while I am going over /home/klinebak with extreme caution-- getting rid of dross while coping everything valid to my new /home/ dir. im hoping that the cp utility is flawless and/or that the drive to this duo/dual-CPU computer is good. I'm buying a new Dell 4-CPU new. Should have everything setup in a couple weeks. Oh, and in addition to klinebak, there are fragments of my backup systems all over the place.
