Thanks for the fast reply Volker,

I tried using this, but get following Errors:

../source3/lib/system.c:1143(sys_popen) sys_popen: ERROR executing 
command '/usr/bin/dfree .': Fehler im Format der Programmdatei (Error in 
format of program file)
../source3/smbd/dfree.c:117(sys_disk_free) disk_free: file_lines_load() 
failed for command '/usr/bin/dfree .'. Error was : Keine Kind-Prozesse 
(no child processes)

This is on Ubuntu 16.04 using Sernet Samba 4.4.7-SerNet-Ubuntu-20.xenial

I get this no matter what I put into the shell script. I even tried 
putting: echo number number into the file

Any ideas?
Jochen
