I need the sum of the size of files in a certain directory and the files in it's sub directories.
this should have done it:
but the thing is it counts empty directories as 4k. I don't want that
, I want empty directories to give 0.
I only want the sum of size of the files.
also, I need for it to only give something like "72M", I don't want the name of the directory/directories/files as output.
