Batchography: Batch files and Unicode

Recently, I had to update my popular utility that resets NTFS files permission to support Unicode paths. I had to investigate how to add Unicode support in Batch scripts. It seems that this was a topic I forgot to add into my comprehensive Batch files programming book.

This article is the result of my investigation, in which I am going to show you how to add Unicode support to your Batch file scripts in 3 easy steps.

Batchography: Changing the MAC address on Windows – A free Batch script

batchography-good-resIn a previous post entitled “How to get unlimited free Internet at Airports“, I showed you how to circumvent the time limit imposed by the “free” Wi-Fi connections in certain airports.

For that trick to work, you were required to update the MAC address of your computer each time the free time is over.

In this blog post, I am going to share with you the ChangeMACAddressBatch script that I wrote with the help and instructions from the excellent Batchography book.

The script makes use of various recipes illustrated in the Batchography book (in Chapter 4) and uses the various Batch scripting language syntax (Chapters 1 and 2) and methodologies (Chapter 3). Therefore, I will not be explaining the script’s contents or how it works because it will become evident if you read the Batchography book.

How to use the script interactively

To begin with, you need to run the script with administrative privileges.

Running the script as an administrator


On Windows 8 and above, just press Win+X and choose “Command Prompt (Admin)” like this:

chg-mac-run-elevated-command-prompt

Otherwise, if you are using the Windows Explorer window, then right-click on your script and choose “Run as Administrator”:

chg-mac-run-as-admin

Starting the script

When you first run the script, you will be presented with the main menu that will show you a list of all the adapters you have on your system.

On my laptop for instance, I have 4 adapters:

  • An Ethernet adapter
  • 2 x VMWare virtual adapters
  • A Wi-Fi adapter

Using the keyboard, type the adapter number that you want to inspect and/or change its MAC address:

chg-mac-main-menu

Let’s press “4” in this case and go inside that adapter’s information screen. Continue reading

Batchography: Building a dynamic menu in Batch files – Part 1

In this article, we will dynamically build a menu around the COLOR command so that the user can change the colors of the console interactively.

To learn more about this technique and the Batch scripting language, please refer to Chapters 3 and 4 in the Batchography book.

Batchography: Embedding an executable file in a Batch script

batchography-good-resIn this blog post, I am going to share with you a recipe from the Batchography book that illustrates and explains in details how to embed executable files in the Batch file script and execute them after they are dropped.

This technique does not rely on using a polyglot Batch file where its first part is actually a Batch script and the other part is a VBS or JScript script. If you want to learn more about how to write polyglot Batch scripts, please refer to Chapter 4 in the Batchography book.
