Pulling CLI Response Data Into Variables?

I'm trying to write a command script in NCM that shows me all of the "notconn" interfaces on a Cisco Nexus switch. That part is easy enough with a "show interface status down | grep notconn | cut -b -14" command. But...once I've got the list of interfaces, I want to iterate through that list of interfaces to grab the *full* description (descriptions are truncated by "show interf status"), with "show interface description | cut -b 30-". Then I'd like to put the interface and description together, outputting each interface and description into a line on the report.

After looking through various example and reading through the variables in the NCM admin guide, I don't think command scripts have this power. I don't see a way that I can pull data output from the CLI and dump it into a variable or iterate through an array. Before I look to perl/expect to do this, am I missing anything?

TIA.

I asked a similar question here and here but did not get a response so far. It seems this is not possible with the current software and I am thinking about filing a feature request about this.

Being able to run scripts that can parse real-time command output and allow the script to react to them would be quite powerful. That said, I did more reading yesterday, and it seems that you can do about whatever you like with data in the Orion database. So for my specific application, I can generate a report that provided a list of interfaces and their statuses, based on the last SNMP polling cycle. What I can't seem to do (so far) is get that output filtered so that I'm only seeing the interfaces I want to see (i.e. admin up, but link down).

At the moment, my best answer is to run a command script that dumps the output to an e-mail. Ugly...only as formatted as the CLI will allow. I'll keep pondering this as time allows. Maybe I really do want perl. Ooooh...I wonder if I can invoke a perl script from within NCM and hand the formatted output off to an e-mail recipient.

In IOS you can use the filter like the example below, maybe there is similar function in NX-OS. If grep really support regular expressions like it says here, you can try using the OR operator "|".
