I have written a function in perl (Thanks to perl monk) The below script works as expected and provides the desired output. I have been learning about functions and making function calls. I'm trying to make a function call by assigning it to a variable. 


use strict;
use Carp;
use warnings;
use autodie;
use feature qw/say/;
use Net::SSH::Expect;

print "\n[INFO] script Execution Started\n";

#-- ssh into a router 

my $ssh = Net::SSH::Expect->new(
  host     => "ip addr",
  password => 'password',
  user     => 'user name',
  raw_pty  => 1,
);

my $login_output = $ssh->login();


 #--Function to read  config file and execute the commands on the rout
+er accordingly.


sub mysub {

my ($ssh,$filename) = @_;
$ssh->exec("cmd 1");
$ssh->exec("cmd 2");
open my $p, '<', $filename;
while (my $config = <$p>)
{
chomp $config;
my $conf =  $ssh->exec("$config");
print("$conf");

}


}

#--> Function call.

mysub($ssh,"file name.txt");

Now I tried making the function call my assigning it to a variable $p and that should throw an error if some thing goes wrong in the function. This is what i tried . 

 my $p = mysub($ssh," file name.txt ");
    if ($p) {
        print {*STDERR} "Something went wrong  [$p]."
          or carp 'Could not print error about the config file';

        return 0;
    }

However this is not working. Any suggestions ?
