openSUSE Leap 15.4 - here: Appimage administration

Hello all, currently I have the problem to extract one single file in an existing AppImage. My idea is: 1) extract the complete AppImage 2) exchange of the incorrect file 3) reassemble the changed AppImage With regard to this, I found an hint under https://wiki.ubuntuusers.de/AppImage/[1] here extraction of AppImage: ./NAME_OF_FILE.AppImage --appimage-extract In openSUSE Leap 15.4 this does not work, because there is no package existing, that could carry out the operation. What to do? Can anyone help? Kind regards Michael Be Free, Be Linux ------------------------------------------------------------- -------- [1] https://wiki.ubuntuusers.de/AppImage/
