Dear Monks,
I've two hash tables: %files_by_channel and %files_by_number.

#!/usr/bin/perl

use strict;
use warnings;
use Data::Dumper;

my $channel_name;

my %files_by_channel = (
            'ch1' => {
                     '00014' => '/foo/oradata/bar/foodb-lob01.dbf',
                     '00008' => '/foo/oradata/bar/foodb-index11.dbf',
                     },
            'ch2' => {
                     '00004' => '/foo/oradata/bar/tools01.dbf',
                     '00019' => '/foo/oradata/bar/foodb-data02.dbf',
                     '00003' => '/foo/oradata/bar/undotbs01.dbf'
                    },
);


my %files_by_number = (
    '00008' => '/foo/oradata/bar/foodb-index11.dbf',
    '00004' => '/foo/oradata/bar/tools01.dbf',
    '00003' => '/foo/oradata/bar/undotbs01.dbf',
    '00019' => '/foo/oradata/bar/foodb-data02.dbf',
    '00014' => '/foo/oradata/bar/foodb-lob01.dbf'
);


#print Dumper \%files_by_channel;
#print Dumper \%files_by_number;

print "\n";

printf "%-10s %-15s %-40s\n", 'File#',  'Channel Name', 'File Name';
printf "%-10s %-15s %-40s\n", '-' x 10, '-' x 15,       '-' x 40;

foreach my $file_number (sort keys %files_by_number) {
    foreach $channel_name ( %files_by_channel ) {
        #TO DO
    }
    printf "%-10s %-15s %-40s\n", $file_number, $channel_name, $files_
+by_number{$file_number};
}

How to integrate (conjoin) information from these two corresponding tables that the result is something like the following?

File#      Channel Name    File Name                               
---------- --------------- ----------------------------------------
00003      ch2             /foo/oradata/bar/undotbs01.dbf          
00004      ch2             /foo/oradata/bar/tools01.dbf            
00008      ch1             /foo/oradata/bar/foodb-index11.dbf      
00014      ch1             /foo/oradata/bar/foodb-lob01.dbf        
00019      ch2             /foo/oradata/bar/foodb-data02.dbf
