Shell Programming and Scripting

How about presenting your solution in here, so others might learn from it?

i think this might be a very dirty solution, so not like someone should learn from that, its somehow working now, but there are still some things im not happy with

Code:

#!/bin/sh
cd "/i-data/64903fcc/"; 
find ./*/ ! -path "*/finished/*" ! -ipath "*/text/*" -name "*.cad" ! -iname "*text*" | while read FN;
	do
		PT1=${FN%/*}; 	#Kompletter Pfad ohne Dateinamen
		PT2=${PT1#*/}; 	#kompletter Pfad ohne ./ am Anfang und ohne / am Ende
		PT3=${PT2%%/*};	#Main Folder, für Trash
		
		mv --backup=numbered 	"${FN}" "./finished/${PT1##*/}.cad"; echo moved "${FN}" "-->" "./finished/${PT1##*/}.cad";
		mv --backup=numbered 	"./${PT3}" "./Trash/"; echo trashed "./${PT3}";

	done

so as i post this here, i got a few more questions:
how can i handle this procedure to stop, when there are more than 1 .cad files in 1 folder? (in my case, it would handle one and delete the rest)
is there a better way of logging the commands instead of my version with echo and >> logfile.log (so i might be to able to log errors aswell?)
how to clear items in trash, older than 7 days (i might checked them for errors inbetween), ive alread tried this with find, but the -delete does not work, if the folders are not empty
