osx - Mac OS X Terminal - Display list of File Types from Subfolders -

i have external hard drive has content of recovered drive. folders have 'recup_dir.xx' names , there on thousand.

i have copied on content can think of, of specific file types using:

find . -type f -name \*.jpg -exec cp \{\} /volumes/somedrive/somefolder/ \; 

i went through file types can think of - want see file types on drive , in sub folders.

what command can use go through folders , sub folders , display 'total's each file type?

du -hcs 

gives total of drive- after total per file type.

can point me in right direction. have thousands of folders , want make sure haven't forgotten file types - want list of them.

thanks in advance.

you can awk (as other scripting languages). here script in awk:

#!/bin/sh find . -type f -ls | awk ' {     type = $11;     if ( type ~ /\./ ) {         sub(/^.*\./, "", type);     } else {         type = ".";     }     sizes[type] += $7; } end {     ( type in sizes ) {         printf "%10d %s\n", sizes[type], type;     } }' | sort -r -n 

it uses array sizes file-suffix index. awk not have built-in sorting, can piping result through sort.
