Thanks, now I know that I need to specify a format in (interactive) to
get my arguments.
The problem is that I'm using (shell-command-on-region) that does not
allow me to insert arguments to the command, and I don't know how the
command is effectively invoked (e.g., piping the region to standard
input, using a temporary file) so I'm not able to "append" my
arguments.
I need a little more help.

Thanks,
Luca
