I'm fairly new to Perl and I can't quite figure out what I want to do from the Llama. My situation: I'm polling a router for a list of output, and dumping that into @int_descriptions. That part's fine. I also have a text file, foo.txt with a bunch of lines of stuff. I need to figure out a way to grep that file and return any term of my array that (case-insensitive) matches any line of that text file. On this scale, efficiency isn't terribly important; I'll have at maximum around 2k lines in the array, and about 50 in the text file. I'm thinking I could also do: 
open FILE,"$filename" or die $!;
    my @other_array = <FILE>;

I've found enough documentation online to be able to grep a single term/regex and spit it out from an array, but I can't figure out how I can do an any to any mapping.
