I am using Net::SSH2 to ssh into a NAS box, and run a command. I can get the command results while I am inside the loop. When I am outside the loop, I don't see the variable if it contains the output. However, I can see the variable if a new value is defined.

In the code below, I assign $result to $_. If I am inside the loop, I can see it. If I am outside the loop I cannot. However, I can define $result="test" before I leave the loop, and I can then see it outside the loop. It appears that I cannot pass the $_ (output of the NAS Command)

How do I pass the $_ outside the loop?

Here is my code: 
#!C:\strawberry\perl\bin
use warnings;
use strict;
use Net::SSH2;
use MIME::Lite;
use Config::Tiny;

my $ssh2 = Net::SSH2->new();
my $ipaddr="w.x.y.z";
my $username="username";
my $password="password";

        $ssh2->connect("$ipaddr") || die "PROBELM - $!";
        
        $ssh2->auth_password("$username","$password") || die "Username
+/Password not right";
        my $chan = $ssh2->channel();
         $chan->blocking(0);
        $chan->exec('export NAS_DB=/nas;/nas/bin/nas_fs -list');
        print "Chan= $chan\n";

my $result;

        while (<$chan>)
{
$result=$_; #Desired output.  Only works inside the loop.
$result='test'; #Used for testing, this works inside and outside of lo
+op
#print $result; #Works
}

print $result; #Works if $result is set, but not with a $_;
print "END";
