Usage :

  1. Put jfindfiles.sh & jfunctions.sh in the Joomla root dir
  2. Make them executable chown +x jf*.sh
  3. Execute ./jfindfiles.sh
  4. Put the file xxx-unused.txt in the images folder with the jdeletefiles.sh
  5. Make jdeletefiles.sh executable chown +x jdeletefiles.sh
  6. Execute it ./jdeletefiles.sh xxx-unused.txt
  7. Files are deleted ;)

Thank you so much!

With the usage comment by user psyray and his files 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!
