In a modern Linux environment, it’s increasingly common to find both PowerShell (pwsh) and Bash installed on the same system. This provides a unique opportunity for system administrators and developers to leverage the strengths of both shells. You can use Bash for its powerful text-processing utilities and then pipe the results to PowerShell for its object-oriented data manipulation, or vice versa. This guide will walk you through the techniques for calling Bash from PowerShell and PowerShell from Bash, enabling you to create powerful, cross-shell automation scripts. ...

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. ...

In any Windows environment, you’ll inevitably encounter a mix of modern PowerShell scripts and legacy Command Prompt (cmd.exe) batch files. Instead of treating them as separate worlds, you can make them work together. Understanding how PowerShell and CMD can call each other is a crucial skill for any system administrator, allowing you to integrate legacy tools into modern automation workflows. This guide will walk you through the techniques for calling CMD from PowerShell and PowerShell from CMD, enabling you to build powerful, hybrid scripts that leverage the best of both shells. ...

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. ...
