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.

Summary


In this chapter, you learned about leveraging PowerShell to interact with disk drives. You started the chapter by learning about the get-disk cmdlet. You continued to leverage the get-wmiobject with the win32_logicaldrive class to query disk information. You then created a switch statement to determine the different disk types. You also learned how to convert bytes to megabytes and gigabytes. You created a function to dynamically convert to different units of measure and round the values to two decimal places. You ended the chapter by creating a disk information script that queries the disks on a system, converts the disk size and freespace, calculates the units of measure, and identifies the drive types.

In the next chapter, you will scan Windows features and the software installed on a system.
