Can't even get the command line options to do anything... using the -d or -p args just brings up the US gui for me and doesn't seem to run any operation at all.
But anyway... what happens when you try to run the same command you mentioned working for files against a folder?
Is this question about working out the correct command line to use for UltraSentry[1] or about how to get Opus to generate the correct command line for UltraSentry[2]?
[1] In which case you'll get a better answer asking in their forum if they have one.
[2] In which case you'll get a better answer here if you tell us what the correct command line is for some example and we can tell you how to make Opus generate it.
