Object pipeline (not text), cmdlets, remoting, process control. Windows/macOS/Linux.","ai_summary":"PowerShell is Microsoft's cross-platform automation shell and scripting language. Unlike POSIX shells it passes .NET objects (not text) through the pipeline, which makes structured automation cleaner. It runs on Windows, macOS, and Linux (PowerShell 7+), supports cmdlets, modules, remoting, and tight integration with the .NET runtime. Common for Windows automation, CI scripts, and orchestrating child processes \u2014 though process lifecycle and timeout handling around Start-Process / background jobs has well-known sharp edges.","ai_features":["Object pipeline \u2014 pass .NET objects, not raw text, between commands","Cross-platform (PowerShell 7+ on Windows/macOS/Linux)","Start-Process, jobs, and runspaces for process + parallel control","Direct .NET interop ([System.*] types available inline)","Remoting (PSRemoting / SSH) for multi-machine automation"]},"url":"https://learn.microsoft.com/powershell","metadata":{"pricing":{"model":"open-source","plans":[{"name":"OSS","price":"$0","features":["MIT licensed","Bundled on Windows","Free install elsewhere"]}]},"key_features":["Object pipeline","Cross-platform (7+)","Process + job control",".NET interop","Remoting"],"ai_optimization":{"seeded_at":"2026-06-01T00:00:00","use_cases":["Windows automation and provisioning scripts","CI/CD steps on Windows runners","Orchestrating child processes and background jobs","System administration across machines via remoting","Glue scripting with direct .NET access"],"seeded_url":"https://learn.microsoft.com/powershell","ai_benefits":"Object pipeline removes brittle text parsing.
