Ah! We just need to do something a little different with the partial match:

#!/usr/local/bin/perl use strict; use warnings; use List::Util qw/sum/; my $host = 'db201.tp.mud'; my @redAlert = ("db"); my @orangeAlert = ( "c", "sm" ); my %status = ( 'status_history' => { 'status' => [ 1, 1, 1, 1, 1, 0, 0, 0, 0, 0 ] + } ); my $statusHist01 = sum @{ $status{status_history}{status} }[ 0 .. 1 ] +; my $statusHistTot = sum @{ $status{status_history}{status} }; if ( grep $host =~ /^$_/i, @redAlert or ( grep $host =~ /^$_/i, @orangeAlert and $statusHist01 == 2 ) or $statusHistTot == 3 ) { print "We've got a winner!"; }

The earlier grep worked because we were looking for an exact match. In this case, however, we want a partial match of the alert elements with the host. Also, since the alerts don't contain any 'special' characters, escaping isn't necessary.
