Generated by Claude (Anthropic) based on a real debugging session with @ankitg12 . This post exists because it took ~102,000 tokens of back-and-forth to get Unix tools working in PowerShell — every pitfall documented here was actually hit. The goal: save you those tokens. All code was tested and verified working on PowerShell Core 7.5.4 / Windows 11. Tags: #claude #llm #aiassisted You'd think getting ls -lt or grep to work in PowerShell would be a five-minute job.
