The document provides an overview of Windows batch scripting, including definitions and examples of internal and external commands. It explains the functionality of the command prompt, command host, and the purpose of batch files for executing multiple commands in sequence. Additionally, it discusses the process of converting batch files to executable files to prevent unauthorized edits.

- 2. Introduction Command: A command is nothing but a word/keyword that instructs the system to do a specific task. Commands are of two types internal and external. Internal Command: An internal Command is the built in Command which is not depended on any other thing. These come with the operating system from the very beginning. Whenever you install an Operating System then the built in commands also get installed. Internal commands might be embedded into a file like Command.com(Windows) or installed individually(Linux). E.g. cls, color, help, dir, cd, date, time External Command: These are external programs downloaded from the internet and after locating the correct path they can only be run. E.g. mp3play, python, node, npm, bcrypt Commands: date /t time /t
- 3. Command Prompt: This is a black screen Application that provides CLI(Command Line Interface). One needs to enter the commands to this window and hit enter. Then the command will be sent to the System’s Shell. Shell is the actual command interpreter. You could open multiple Command Prompt windows and each will have distinct Process IDs. Their job is to only taking the Command from the User. Command Host: A Command is either the built-in one or external program. They need to communicate with the Command Host/Command Processor. Which is nothing but the Shell and more precisely Command Shell. Be it command shell or power shell, they all belong to the Operating System’s Shell compartment.
- 4. Windows Batch File: Batch refers to the batch execution of commands. If you want to execute 100 commands in a sequence then batch file is the solution. Instead of manually entering commands one by one you create a list of those commands in a TextEditor and save the file with .bat extension.
- 5. Generate Executable from Batch File: A Batch File is editable anytime. That make the Script vulnerable to unwanted change of source code. In order to make a batch file non editable one has to convert the file to exe. This process is also known as .bat to .exe. Using Third Party Software: Developer: Fatih Kodak(Germany)
