Recursive dwdiff using find -exec

find DIR -exec sh -c "if [ -f \"{}\" ]; then echo {} >> dwdiff.txt; dwdiff --no-common {} /OLD_FILES/{} >> dwdiff.txt; echo \"--EOF--\" >> dwdiff.txt; fi" \;
Recursively compares files in directories DIR and OLD_FILES using dwdiff Word-by-word comparison with dwdiff results in words unique to NEW file versions in the DIR directory tree shown enclosed in [- SQUARE BRACKETS -] and words unique to OLD file versions in the OLD_FILES directory tree shown enclosed in {+ CURLY BRACES +} Note: does not detect files unique to the OLD_FILES directory tree.
Sample Output 
Can't open file /OLD_FILES/new_file1: No such file or directory
Can't open file /OLD_FILES/new_file2: No such file or directory

dwdiff.txt contains output:
./DIR/file1

{+OLD+}
======================================================================
