This is how I would do it:

# *perl*
use strict; use warnings;
use Getopt::Std;

our ($opt_n, $opt_g);
getopt('n');

if (! $opt_n || ! $opt_g) {
    print "usage: $0 -n numberlist -g globpattern\n"
        . "  where numberlist are numbers separated by commas,\n"
        . "  e.g. -n 1203,0815,22222\n";
    exit;
}
my %matches;
$matches{$_} = 0 for split /,/, $opt_n;
$opt_n =~ s/,/|/g;
my $re = qr{\b($opt_n)\b};

@ARGV = <$opt_g>; # set @ARGV to found files 

while(<>) {
    my @m;
    @m = $_ =~ /$re/g and @matches{@m} = (1) x @m and print "$ARGV $_"
+;
}

my @nomatch = grep { ! $matches{$_} } keys %matches;
if(@nomatch) {
    print "$_ not matched\n" for @nomatch;
}

Of course, TIMTOWTDI (there is more than one way to do it)
