Overview of this book

PowerShell Core, the open source, cross-platform that is based on the open source, cross-platform .NET Core, is not a shell that came out by accident; it was intentionally created to be versatile and easy to learn at the same time. PowerShell Core enables automation on systems ranging from the Raspberry Pi to the cloud. PowerShell Core for Linux Administrators Cookbook uses simple, real-world examples that teach you how to use PowerShell to effectively administer your environment. As you make your way through the book, you will cover interesting recipes on how PowerShell Core can be used to quickly automate complex, repetitive, and time-consuming tasks. In the concluding chapters, you will learn how to develop scripts to automate tasks that involve systems and enterprise management. By the end of this book, you will have learned about the automation capabilities of PowerShell Core, including remote management using OpenSSH, cross-platform enterprise management, working with Docker containers, and managing SQL databases.

Introduction

Performing calculations is an integral part of automation. Of course, PowerShell allows for it. PowerShell also takes things up a level by providing administrators with what is called administrative constants, which help ease calculations (which will be addressed in the following recipes). We will first look at common arithmetic operations, and then move toward using the concepts on outputs using calculated properties, as we saw in Chapter 4, Passing Data through the Pipeline.

We will also look at cases where we could ease automation using binary numbers to identify flags, perform base conversion, and, finally, use some of the .NET accelerators or cast operators to simplify scripting.
