I thought you knew it already?

List them in which context?  On a machine on which you run this script?

Wow.  I guess that depends on what you mean, huh?

Ok, so that suggests that what you're *actually* trying to do is

"Create a script that Nagios users can run on a specific machine which
provides public TCP services, which will produce as output Nagios
monitoring definitions to watch those services, when installed on a
Nagios monitoring console."

Is that it?

It will show up as broken.

I suspect the former won't work but the latter will, but I'm somewhat
of a newbie, as well.

PS: don't send HTML email to mailing lists, 'k?
