One of PowerShell’s most powerful and defining features is that it is built directly on the .NET runtime. This isn’t just a superficial connection; PowerShell’s engine, its cmdlets, and the data that flows through its pipeline are all .NET objects. This deep integration gives PowerShell a “superpower”: the ability to directly and seamlessly access the vast ecosystem of .NET classes and methods. This guide will walk you through how this relationship works and how you can leverage .NET to write incredibly powerful and flexible scripts, turning PowerShell into a full-fledged .NET scripting language. ...

What truly sets PowerShell apart from traditional command-line shells like Bash or Zsh is its foundational design: it’s built around objects, not text. While other shells pass streams of text between commands, PowerShell passes rich, structured objects. This fundamental difference is PowerShell’s superpower, making it an incredibly efficient and robust tool for automation, data processing, and system administration. This guide will explore what it means to work with objects and how you can leverage the object-oriented pipeline to write cleaner, more powerful, and more reliable scripts. ...

For decades, Bash (Bourne Again Shell) has been the undisputed king of the command line on Linux and other Unix-like systems. It’s powerful, ubiquitous, and has a rich ecosystem of tools built around it. However, with Microsoft open-sourcing PowerShell (pwsh) and making it fully cross-platform, a new contender has entered the Linux arena. So, which shell should you use? This guide provides a head-to-head comparison of PowerShell and Bash, exploring their fundamental differences in philosophy, syntax, and capabilities to help you choose the right tool for the job. ...

PowerShell has evolved significantly over the years, and with the release of PowerShell 7, it introduced several modern operators that make scripting more efficient, readable, and aligned with other popular programming languages like C# and JavaScript. This guide provides a deep dive into these new operators, showing you how they can simplify your code and make your scripts more robust. The key operators we’ll cover are: && and || — Pipeline chain operators ?? and ??= — Null-coalescing operators ?: — Ternary operator 1. Conditional Execution: The Pipeline Chain Operators (&& and ||) Introduced: PowerShell 7.0 ...

If you’ve worked with PowerShell, you’re likely familiar with powershell.exe. But in recent years, a new executable has emerged: pwsh.exe. So, what is pwsh, and how is it different? In short, pwsh is the executable for modern, open-source, and cross-platform PowerShell (version 6 and newer). It represents a fundamental evolution of PowerShell, transforming it from a Windows-only tool into a powerful automation language for any platform. This guide will explore the history of pwsh, its key features, and why you should be using it for all your new scripting and automation projects. ...
