coreutils ls summary option
The coreutils ls should have a summary option.
Count the Files and Dirs incl. Subdirs and indicate the exact Sizes.
Because -s is used, I choose -j|--journal.
You can set a thousands separator. By default, there is none and the whole option is turned off.
You can force off with -J|--no-journal.
