I suspect you don't want to do it that way.

No, if you can get to that point from the command line on the
monitoring machine, then you should be ok into Nagios, I would expect.

I see that the first hyphen on the response line is *not* followed by a
space, as I've come to expect... but I'll defer to Gerhard and others
on the formatting of the plugin return string; that's magic deeper than
mine at the moment.
