Batchography: How to do a “switch/case” in Batch files

You have found this blog post because you are wondering if there is a way to express a “switch/case” logic in Batch files.

The short answer is NO, not exactly. However, there are ways to achieve the same in Batch files.

In the Batchography book, I explain in details the “switch/case” construct, but in this blog post I will illustrate this mechanism briefly. For more advanced Batch scripting topics, please grab a copy of the Batchography book.

  • Page Up / Page Down.

3 easy steps to setting up a zero configuration multi-platform web server with NodeJS and local-web-server

In this technical post I am going to illustrate how you can use the simple local-web-server package for NodeJS to start your web server in a few commands.

Let’s get started!

Step 1 – Installation

First, install NodeJS from http://nodejs.org/download/

If you are using Windows, then make sure you download the MSI package because it is so easy to install.

Keep the default options as you’re installing:

After installing NodeJS, open an elevated command prompt (i.e: run cmd.exe as Administrator) and type the following command in order to install the local-web-server package:

npm install -g local-web-server

You should see something like this:

No errors imply that the package has been successfully installed! Continue reading

How to turn your bookshelf into an e-book library: Digitizing all of your books

digitizing-books-scannedSince I moved to the US, I collected around 350 books. I love books and the thought of giving them up is not a pleasant thought.

Each time I used to move from an apartment to another, the majority of boxes would be packed with books. Each time I travel somewhere for a long period, I miss being able to grab a book from my bookshelf and start reading (most of my books are old and they do no exist in digital format anyway). It is clear that I have attachment to those books.

To break this attachment, I had to make a couple of decisions. The first was whether to just forget about the books, leave them on the shelves and get myself busy with another chore. The other decision was whether to scan and /or give away the books. With that came other questions like how to scan books and convert them to eBooks, what methods to use, how much efforts would it take to convert the books, etc.

I decided to get rid of the books and the trim down on the space they occupy. For the reasons outlined later in this blog post, I chose to destructively scan my books. By scanning the books, I get a digital and searchable copy of my books (in PDF format).

In this blog post, I will share with you different ways you can use to digitize books and then the remainder of this blog post will illustrate how I destructively digitized all of my books and what tools I used. Continue reading

Batchography: How to check if your Batch file script is running as an Administrator

In chapter 4 of the Batchography book, I illustrate 3 methods that you can use to check if your Batch file script is running as an Administrator.

In this blog post, I will share with you the method entitled “Using known commands that fail to run without elevated privileges” from the book.

The idea behind this method is to run commands that are known to fail and return a non-zero error code if they are not executed with administrative privilege.

The Batch script would then check the return code and act accordingly:

@echo off


:: 
:: The Batchography book by Elias Bachaalany
::


net session >nul 2>&1

if %errorlevel% neq 0 (
  echo Requires administrative privilege.
  goto :eof
)

echo Script starts here...
