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 how to compose a Windows server scanning script. You started the chapter learning about the structure of the Windows server scanning script. You proceeded to the core scripting components section where you defined the comment block, parameter block, created the answer file reading function, the decryption function, populated the answer files, created the script's logs and logging functions, and created the check-kill function.

You continued creating the script by creating functions for scanning disks, scheduled tasks, processes, Windows services, software, user profiles, Windows features, and directories for files containing strings. You then created a section to query if the scanning script functions were enabled and invoked the functions if they were. You completed the script by commenting the end of the script file and copying the log and CSV files to a UNC path. You learned how to start the Windows server scanning script from the command line with...
