in thread compare two files by column and return second (matching) column

You're most welcome, ejbiers! Yes, the script below includes printing the results to a file:

use Modern::Perl; open my $fhA, '<', 'FileA.txt' or die $!; my %hash = map { /(.+)\t(.+)/; $1 => $2 } grep /\S/, <$fhA>; close $fhA; open my $fhB, '<', 'FileB.txt' or die $!; my @output = map { chomp; $hash{$_} } grep /\S/, <$fhB>; close $fhB; open my $fhO, '>', 'Output.txt' or die $!; say $fhO $_ for @output; close $fhO;
