BASH. Обновленный скрипт для массового изменения конфигурации коммутаторов (telnet)

Обновление скрипта https://ip-connection.blogspot.ru/2016/09/telnet.html

Оптимизировал слегка скрипт. 

Строка для запуска : 

./script.sh ipaddr.lst commands.lst

Где : 

script.sh - сам скрипт 

ipaddr.lst - файл содержащий IP адреса устройств на которых необходимо выполнить команды. 

commands.lst - файл содержащий перечень команд для выполнения на устройствах.

Содержимое файла script.sh

#!/bin/bash

# This is remote telnet exec script.
