Thank you so much renekreijveld, wehseman and psyray!

With the usage comment by user psyray and his adapted files (as commented above) I was able to get it to work (I'm new to ssh).
I learned

• SSH access is needed for this (found on webhost help pages how to do that)
• putty (putty.org) is a nice program for SSH access
• with ls -lh there is a list of who owns the files and what the permissions are (the user that uses Putty has to have execute rights) and via ftp the chmod command changes the permissions

There were three errors for the jfunctions.sh file

grep: ./libraries/cms/version/version.php: No such file or directory
grep: ./libraries/cms/version/version.php: No such file or directory
grep: ./libraries/cms/version/version.php: No such file or directory

just because the version directory does not exist in in my Joomla 3.9.6 installation. That is not a problem at all though!

First of All let me say T H A N K S ! to Author Rene for sharing this fantastic "time saving" script.

It works fine on my joomla 3.x

Some notes

MANDATORY
2 files:

• jfindfiles
  https://gist.github.com/renekreijveld/27d9062b941a2d0c80f3-
• jfunctions
  https://gist.github.com/renekreijveld/9663741
• SSH Session, better if you use root

STEPS

• Download and upload jfindfiles and jfunctions on your joomla root, in my case in keep joomla on site folder
• chmod +x jfindfiles (I also done for jfunction but I think it's not necessary)
• ./findfiles

OUTPUT
findfiles created 2 files : mysitename-notused.txt and mysitename--used.thx
