Thanks for the hints Nick.

My rudimentary shell scripting produced this script which does what I need.
If someone can offer any improvements on it terrific.
I actually have to check 2 locations, since I stored recordings in 2
different locations.  I just removed the second check from the script.
I don't know if it is possible to ask Myth for the recording directory
locations (to make the script more generic) but it is a simple change
as is if things move.
