list unique file extensions recursively for a path, include extension frequency stats

find /some/path -type f | gawk -F/ '{print $NF}' | gawk -F. '/\./{print $NF}' | sort | uniq -c | sort -rn

If you have GNU findutils, you can get only the file name with find /some/path -type f -printf '%f\n' instead of find /some/path -type f | gawk -F/ '{print $NF}'

Sample Output

100 txt
 25 gz
 10 vim
  3 gitignore
