About the Book
PowerShell Programming in 2026 is a thorough, idiomatic guide to PowerShell for developers, sysadmins, and DevOps engineers who already write code in Bash, Python, or another general-purpose language but haven't used PowerShell extensively. Rather than treating it as a glorified shell, this book treats PowerShell 7 (the cross-platform, .NET-based runtime, with PowerShell 7.6 as the current LTS release) as a serious programming language worth learning on its own terms.
Across twelve chapters, you'll master the object pipeline that sets PowerShell apart from text-based shells, write advanced functions with parameters and validation, handle errors the way production code demands, package your work into modules with PSResourceGet, wrangle JSON, XML, and CSV data, tap directly into .NET when built-in cmdlets aren't enough, remote into fleets of Windows and Linux machines, and test and lint your scripts with Pester and PSScriptAnalyzer. The final chapters connect all of it to real-world DevOps work: cloud automation on Azure and AWS, CI/CD pipelines on GitHub Actions and Azure DevOps, and the security practices that keep production scripts safe.
Every concept comes paired with runnable, realistic examples, not toy snippets. By the end, you'll be able to read an unfamiliar PowerShell script and understand every line, write your own advanced functions and modules, test and ship them with confidence, and run your automation across a mixed fleet of Windows, Linux, and macOS machines from a single session.

About the Author
SouthStone Publications
The founder of SouthStone Publications draws on more than twenty years in IT and cybersecurity, bringing that depth of experience into everything he writes. At heart, he's a technologist through and through: part enthusiast, part researcher, part engineer, part technical leader, having grown up alongside the internet itself and evolved right along with it.
His career sits at the crossroads of system design and cybersecurity, approached from both the offensive and defensive sides of the discipline. Over the years, he has built a reputation for turning complex, often intangible technical knowledge into practical guidance that professionals can actually put to work.
He currently serves on the leaderships in engineering and cybersecurity team at a leading IT services company in its industry, where he relentless studies emerging AI technologies and also cyber threats while helping organizations navigate the risks already at their doorstep. His expertise spans an unusually wide range of disciplines, consists of security engineering and development, project management, application security, infrastructure security, vulnerability management, reverse engineering, penetration testing, security architecture, incident response, and threat hunting and intelligence. He is equally at home diagnosing a flawed system architecture from the ground up, dissecting a sophisticated piece of malware, or leading red team operations against live threats - moving fluidly between granular technical detail and big-picture strategy in a way that few in the field can match.
Besides his astounding professional career experiences, he has partners with subject matter experts with backgrounds in technical writing, focused on AI, IT and security education, producing technical books and training programs that have helped countless developers, analysts, and practitioners build more resilient systems. That same dedication to clarity, rigor, and real-world relevance defines his work with SouthStone Publications, where deep technical expertise meets a mission to make security knowledge accessible, actionable, and built to be sustainable, lasting and progressive. SouthStone Publications is the first publisher of Cybersecurity category books in LeanPub.
