Still not understanding grep and array of arrays... I wrote a the test listed below to figure this out and I am having no luck. What am I missing? Could some please give me an example of the working command thenexplain how it works. I can get grep to work in a normal array, but not when I move to array of arrays. Is grep not the best way to perform a substring seach and return the array or an index to the array that matches? I left in some of the things I have tried. 
#!/usr/bin/perl

use strict;

my @test2 = (["KATE","1001"],
["XERXES","1002"],
["LARRY","1003"],
["TEDDY","1004"], 
["DANA","1005"], 
["SHERRY","1006"]); 

#my ($grepnames) = grep{$_ eq "ER"} @test2;
#my ($grepnames) = grep(/"ER"/, @test2);
my @grepnames = grep {$_->[0] eq "ER"} @test2;

print ("@grepnames\n");
