Whenever you want to open a file with a program that's not in the right-click shortlist, you click 'use a custom command.' However, the way that's worded led me to believe that it may be possible to treat the file as if it were
$@, command line input.
What I want to be able to do is add the custom command 'cp (clickedfile) /my/directory'...
However, the custom command 'cp $@ /my/directory' did not work.
