RE: (2) extract uniques and sort (thanks, getting closer))

Thanks Fastolfe, for an informative reply, also to japhy, geektron, and I think tilly in the Chattbox.

Actually, I'm looking for unique strings that happen to be hostnames. The list is built using a variation of (code)) Cisco Pass Mass - IOS (deprecated by node 123464) to query a core switch for CDP neighbors (wiring closet "top o' stack" switches). Next I feed the output back into the same script to find remaining switches in each wiring closet stack. Then, I'll feed the complete list of core+closet switches back into the original (code)) Cisco Pass Mass - IOS (deprecated by node 123464) script to implement my config updates.

I've now got my hands on the Perl Cookbook, pouring over example 4.6. Looks like I'm getting closer to a solution. Keys of Hash, eh?
cheers,
ybiC

If you can get the list into an array, this node can take you the rest of the way: How can I extract just the unique elements of an array? Good luck.	[reply]
