OK, but you are still not trying to do what I suggested.
Minimize your code and create much smaller pieces of test code so you will be able to learn how to debug your own code.
I'll give you another example what I am talking about. In the next piece of text code I have found multiple problems, so play around with it a little bit and try to fix it yourself:
use strict;
use warnings;
use Data::Dumper;
my ($file_1, $file_2) = ('output1.csv', 'output2.csv');
open my $fh, '<', $file_1 or die "Can't open $file_1: $!";
my %first = map { chomp; split /\s*,\s*/ } <$fh>;
print Dumper( \%first ) ;
open $fh, '<', $file_2 or die "Can't open $file_2: $!";
my %second = map { chomp; (split /\s*,\s*/)[1,2] } <$fh>;
print Dumper( \%second ) ;
foreach my $name (sort keys %first) {
if (not exists $second{$name}) {
print "Devices should be added: $name\n";
next;
}
if ($first{$name} eq $second{$name}) {
print "Match found $name, $first{$name}\n";
} else {
print "UPDATE need be done for $second{$name}\n";
open ( my $input_1, '<', 'output1.csv' ) or die $!;
while ( <$input_1> ) {
chomp;
print " input_1 = $_\n" ;
my ($name_1, $ip_1) = split /,/;
print " (1) $name, $ip_1\n" ;
(my $id, $first{$name}, $second{$name}) = split /,/;
print " (2) $id, $first{$name}, $second{$name}\n" ;
}
}
}

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).
