See below for a great shell command to get a listing of the count of files in all the folders in the current directory and below. It will produce an output similar to the following which can then be manipulated in a data-processing application:

1  ./example/dir1 
256./example/dir2 
3  ./example/dir3/dir4/dir5 
10 ./example/dir3/dir4/dir6 
67 ./example/dir3/dir4/dir7

Command:

find . -type f -printf %h"\n" | sort | uniq -c
