Ah! Then the following should work:
use strict;
use warnings;
use File::Slurp qw/read_file/;
my ( $hash1, $hash2 ) = @ARGV or die $!;
my %hash1 = map { /(.+?),(.+)/; $1 => $2 } grep /.,./, read_file $hash
+1;
my %hash2 = map { /(.+?),(.+)/; $1 => $2 } grep /.,./, read_file $hash
+2;
for my $key2 ( sort keys %hash2 ) {
for my $key1 ( sort keys %hash1 ) {
print "$key2\t$hash2{$key2}\t$key1\n" if $hash1{$key1} =~ /\b$
+hash2{$key2}\b/;
}
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
