Enterprise PowerShell Scripting Bootcamp

By: Brenton J.W. Blawat

Overview of this book

Enterprise PowerShell Scripting Bootcamp explains how to create your own repeatable PowerShell scripting framework. This framework contains script logging methodologies, answer file interactions, and string encryption and decryption strategies. This book focuses on evaluating individual components to identify the system’s function, role, and unique characteristics. To do this, you will leverage built-in CMDlets and Windows Management Instrumentation (WMI) to explore Windows services, Windows processes, Windows features, scheduled tasks, and disk statistics. You will also create custom functions to perform a deep search for specific strings in files and evaluate installed software through executable properties. We will then discuss different scripting techniques to improve the efficiency of scripts. By leveraging several small changes to your code, you can increase the execution performance by over 130%. By the end of this book, you will be able to tie all of the concepts together in a PowerShell-based Windows server scanning script. This discovery script will be able to scan a Windows server to identify a multitude of components.

Chapter 7. Determining Disk Statistics

Another important component to evaluate with the Windows server scanning script is disk statistics. Whether you are scanning to the identify configuration or scanning to replace a system, it's important to evaluate the full disk configuration. Through PowerShell, you have the ability to gather information about your physical disk layout, your logical disk layout, and even removable devices plugged into your system. This can be helpful to identify USB licensing key devices, or even external hard drives plugged in to back up the system.

The Windows server scanning script can also enable you to view the disk size and free space of all devices connected to the system. This information can be helpful in the event that the system is running low on disk space, or if the drive sizes don't conform to your corporate standards. This chapter will enable you to get detailed visibility into the disk configuration on your systems.

In this chapter, we discuss the following...
