I'm searching for exceptions containing logic, not only class ... extends ..., so I searched for a way to get the real file size.

What didn't work

# only lists directories
find . -type f | du | grep Exception

# lists files in block size (4kb) which isn't accurate enough
find . -type f | du -a | grep Exception

What I ended up with:

find . -type f -print0 | xargs -0 stat -f "%z - %N" | grep Exception | sort
