You might do well to ask the Oracle known as Google. This be what I hit first try with "unix directory change notification": http://aplawrence.com/Unixart/watchdir.html The top of the dir tree will tell thee dates and times that contents changed below/within it, so one could just scan the root 'customer' dirs first to see which one has been modified, then traverse it and work thine magic. Order them with this incantation "ls -lct" and pop off the top ones for 'todays date' or 'hour' or something might also get you more closer to what you want. rinse. repeat. I'm out of wizard puns. ;-)
