It does not work for me:

% ls
000misc/                  Front242/            Ministry/
VNV_Nation/
Aavikko/                  Frontline_Assembly/  Nitzer_Ebb/
Wendy_Carlos/
Apoptygma_Berzerk/        Kemopetrol/          Organ/            YMO/
Art_of_Noise/             KMFDM/               Rammstein/
Coil/                     Kraftwerk/           Revolting_Cocks/
Einstuerzende_Neubauten/  Laibach/             Type_O_Negative/

% du -B 1 -s -0 * | sort -nz | awk -v RS='\0' '{print $2}' | xargs -d
'\0' du -sh
du: tiedostoa

ei voi käsitellä: Tiedostoa tai hakemistoa ei ole
[1]    21748 done       du -B 1 -s -0 * | 
       21749 done       sort -nz | 
       21750 done       awk -v RS='\0' '{print $2}' | 
       21751 exit 123   xargs -d '\0' du -sh

It says ”du: A file (very long text) can not be handled: File or
directory do not exist.”

% whence -savc awk
/usr/bin/awk -> /usr/bin/gawk

How that awk-snippet is actually used? Can you provide it as a
shell-script-file?
