I'm not sure what on earth you're doing in your code, you have 2 loops using $_ and you pull a magic $fileTowValue out of thin air.

Here is something that works:

my @file1 = qw(22-28 36 44-49 234 77 26); my @file2 = qw(23 11 21 44 233 26); my %wanted = (); foreach my $num (@file1) { if ($num =~ /^(\d+)-(\d+)$/) { $wanted{$_}++ for $1 .. $2; } else { $wanted{$num}++; } } foreach (@file2) { print $_, "\n" if $wanted{$_}; } __END__ Output: 23 44 26
