Hello, I have written a perl script that reads information form text file and executes some commands.

use strict;
use warnings;
use autodie;
use Net::SSH::Expect;

# ssh into a router 

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

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

# execute the commands

$ssh->exec("command 1");
$ssh->exec("command 2");

# open a file and read the config information

open my $prep, '<', 'config.txt;
while (my $config = <$prep>) {
chomp $config;
my $conf =  $ssh->exec("$config");
print("$conf");

}

the above code works and provides the required output. However i would like to convert this code into a function so that i can reuse this for various config files.

For instance: If I make the following function call  config_function("config2.txt"); The script should read that 2nd config file and execute the commands.Is it possible to do that.? suggestions please.
