I just tried:
If I hit 'tab' at this point, it just beeps. And if I complete the line manually and close with speech marks, it gives me the same, no such file or directory
So it appears as though tab completion is not working or can't see the file.
Got a little further, I dragged the file to the terminal window and got this:
'/home/cafesupport/Desktop/Make Usplash 1.04'
bash: /home/cafesupport/Desktop/Make Usplash 1.04: Permission denied
sudo 'home/cafesupport/Desktop/Make Usplash 1.04'
sudo: /home/cafesupport/Desktop/Make Usplash 1.04: command not found
