About these scores

OSS scale score is an unbounded metric that log-compresses and weights Stars, Watchers, Forks, and Contributors. Discovery score is the current OSS scale score minus the score at discovery. Update pace is commits in the last 30 days, growth momentum is the OSS scale score difference within the recent observation window, and OSS health is a 0–100 rating based on available recency, Community Health, and release data.

Overview

PowerShell is a cross-platform command-line shell, scripting language, and cmdlet framework for Windows, Linux, and macOS. Pipelines pass .NET objects rather than only text, enabling property-aware processing of processes, files, JSON/CSV/XML, REST APIs, and other structured data.

Features and best fit

Based on official documentation; not hands-on tested · Content checked:

Pipe objects through filters, sorting, and transformations

Cmdlets pass .NET objects with their properties intact, allowing Where-Object, Sort-Object, Select-Object, and other commands to operate structurally.

Sources: [2][4]

Combine system administration, REST APIs, and structured data

PowerShell brings OS management, JSON, CSV, XML, REST APIs, and .NET object models into one scripting environment for automation.

Sources: [2]

For cross-platform operational scripts and administration

PowerShell suits teams that want object-oriented automation shared across Windows, Linux, and macOS rather than separate shell approaches for each platform.

Do not confuse PowerShell 7+ with Windows PowerShell 5.1

The README states that changes in this repository are not ported back to Windows PowerShell 5.1 and that repository issues target PowerShell 7.x and later. Check module compatibility when migrating older Windows scripts.

Supplemental curator note

Unlike text-oriented Unix pipelines, PowerShell passes .NET objects between cmdlets, preserving properties for filtering, sorting, and serialization. This repository tracks PowerShell 7.x+; Windows PowerShell 5.1 is a separate legacy line and does not receive changes from this repository.

Try it in 3 steps

  1. 1

    Install PowerShell 7+

    Use the official installation instructions for Windows, macOS, or Linux.

    https://learn.microsoft.com/powershell/scripting/install/installing-powershell
  2. 2

    Try an object pipeline

    Sort and select process properties while preserving structured objects through the pipeline.

    pwsh -NoProfile -Command "Get-Process | Sort-Object CPU -Descending | Select-Object -First 5 Name,CPU"
  3. 3

    Process JSON as an object

    Parse JSON and inspect named properties instead of treating the data as plain text.

    pwsh -NoProfile -Command "'{"name":"demo","enabled":true}' | ConvertFrom-Json | Select-Object name,enabled"
