Batch Scripting

3 days

Overview

Batch programming, also known as batch scripting, refers to writing scripts in a plain text format to execute commands sequentially in a command-line interpreter. The most common environment for batch scripting is the Windows operating system, where these scripts are typically saved with a .bat or .cmd file extension. Batch programming has been a fundamental tool for system administrators, IT professionals, and power users for decades, enabling them to automate tasks, manage files, and control system operations efficiently.

This course will cover the fundamental concepts, explore advanced techniques, and apply the skills to solve real-world problems through hands-on activities.

Objectives

• Grasp the fundamentals of batch scripting, including syntax, basic commands, and file operations.
• Explore advanced scripting concepts such as flow control, functions, error handling, and network scripting.
• Develop and deploy scripts to automate routine tasks, enhance productivity, and manage network operations.
• Learn best practices for writing maintainable, secure, and efficient scripts.
• Understand how to integrate batch scripts with other scripting languages and Windows utilities.

Target Audience

IT Professionals, System Administrators or Developers looking to automate repetitive tasks and manage systems more efficiently.
