PowerShell

If you are still launching the blue icon named “Windows PowerShell”, you are using technology from 2016. pwsh (PowerShell 7+) is the modern, open-source, and cross-platform evolution of PowerShell. It runs on Windows, Linux, and macOS, and it’s the future of PowerShell. This guide explains why you should be using modern PowerShell and provides a complete, step-by-step tutorial for installing it on both Windows and Linux. Why Switch to Modern PowerShell? Windows PowerShell (v5.1): Built on the legacy .NET Framework. It is included with Windows but is now in maintenance mode, receiving only security fixes. PowerShell (v7+): Built on modern .NET. It’s open source, receives active feature updates, and is optimized for cloud and cross-platform automation. PowerShell 7 runs side-by-side with the older Windows PowerShell, so you can safely install it without breaking legacy scripts. Key features include: ...

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 walks through how this relationship works and how I 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 explores what it means to work with objects and how I leverage the object-oriented pipeline to write cleaner, more powerful, and more reliable scripts. ...

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 how I use them to simplify my code and make my scripts more robust. The key operators I’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 ...
