I want to mount iso files without root permission by fuseiso, and this is how to mount a iso file:

fuseiso -p '/path/to/isofilename' '/media/isofilename'

, so I make a .desktop file followed Freedesktop Standard (The Exec key) as bellow:

#!/usr/bin/env xdg-open

[Desktop Entry]
Name=Mount ISO image
Name[zh_TW]=???????
Exec=fuseiso -p %U "/media/$(basename %U)"
Terminal=false
MimeType=application/x-cd-image

, but it failed.

I think it failed because of $(basename %U), if it is changed to a fixed string, the iso file can be mounted.

How can I solve this problem?
