How to Write a Script in Batch File: A Comprehensive Guide

Creating a script with batch files can significantly streamline tasks on Windows. Here’s how to get started.

What is a Batch File?

A batch file is a text file with a .bat or .cmd extension that contains commands for the Windows command interpreter. These files can automate various tasks, such as file management and system configurations.

Creating Your First Batch File

1. Open Notepad: Write your commands and save the file with a .bat extension (e.g., example.bat).

Example:

@echo off
echo Hello, World!
pause

• @echo off: Hides the command prompt display.
• echo Hello, World!: Prints text.
• pause: Waits for a key press.

Running Your Batch File

• Double-click the file in File Explorer.
• Command Prompt:

  cd path\to\your\batchfile
  example.bat
  

Common Batch Commands

• echo: Displays messages.
• cls: Clears the screen.
• pause: Pauses execution.
• rem: Adds comments.
• set: Manages environment variables.
• if: Executes conditional statements.
• goto: Jumps to labeled lines.
• call: Calls another batch file.
