The quick start guide for an advanced enterprise PowerShell framework
About This Book
Introduces industry-proven techniques that improve script efficiency and reliability
Example-rich guide based on real-world scenarios
Facilitates building a script that can fully scan a Windows server and identify components
Who This Book Is For
This book is for IT professionals and Windows administrators who would like to gain intensive,hands-on knowledge and skills on PowerShell without spending hours and hours in learning. If you have been struggling to find the time to gain proficiency and confidence with PowerShell and everyday scripting tasks
What You Will Learn
Create an advanced PowerShell scripting template that provides repeatable code to jumpstart all of your scripting projects
Learn how to securely encrypt and store usernames,passwords,and other sensitive data in PowerShell scripts and answer files
Understand how to optimize the performance of scripts to help process large datasets quickly and avoid time-consuming mistakes
Develop a script to scan for non-standard Windows Server configurations and identify service accounts used on Windows Servers
Gather a large list of data from a Windows server without locally or remotely logging in interactively
In Detail
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.
