SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill eliminates the frustration of writing scripts that break when run on different operating systems or PowerShell versions, saving you hours of debugging cross-platform compatibility issues.

Core Features & Use Cases

  • OS & Runtime Detection: Automatically identifies the host operating system (Windows, macOS, Linux) and PowerShell edition/version (5.1 Desktop vs 7+ Core) to avoid mismatched syntax.
  • Compatibility Guidance: Provides clear mappings for PS7+-only features to PS5.1-safe equivalents, and workarounds for cross-OS tool differences like sed -i flags and path separators.
  • Use Case: If you maintain a project with contributors using different operating systems, use this Skill to write setup and build scripts that run reliably for everyone without version-specific failures.

Quick Start

Use the cross-platform-scripting skill to adapt the existing project setup script to run correctly on both Windows PowerShell 5.1 and macOS bash.

Frequently Asked Questions about cross-platform-scripting

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I write cross-platform shell scripts that work on Windows, macOS, and Linux?▼

Cross-platform shell scripts require detecting the host operating system and adapting syntax to avoid mismatched tooling. This Skill identifies the OS and PowerShell version, mapping PS7+-only features to PS5.1-safe equivalents and replacing GNU-only flags with BSD-compatible alternatives.

Why does my PowerShell script fail on Windows 5.1 but work on PowerShell 7?▼

PowerShell scripts fail across versions when PS7-only syntax runs on PS5.1 hosts. This Skill detects the PowerShell runtime version and provides clear mappings for PS7+ features to PS5.1-safe equivalents, preventing version-specific script failures.

What's the best way to handle sed -i differences between macOS and Linux in bash scripts?▼

Handling sed -i differences requires cross-OS tool detection to avoid GNU-only flags on BSD/macOS systems. This Skill provides compatibility guidance and workarounds for cross-OS tool differences like sed flags and path separators in shell scripts.

Can I use the same .ps1 and .sh scripts for contributors using different operating systems?▼

You can share scripts across operating systems by detecting the host OS and runtime before execution. This Skill adapts .ps1, .sh, and .cmd scripts to run reliably for contributors on Windows, macOS, and Linux without version-specific failures.

How do I fix POSIX shell scripts that assume Windows-specific path separators?▼

Fixing POSIX shell scripts requires replacing Windows-specific path assumptions with cross-platform logic. This Skill detects the host OS and applies compatibility guidance for path separators and other cross-environment tool differences.

Does this approach support debugging existing .cmd and .sh files for cross-platform compatibility?▼

Debugging cross-platform compatibility applies to writing, editing, and debugging .ps1, .sh, and .cmd scripts. This Skill detects host OS and PowerShell runtime versions to identify and resolve mismatched syntax across Windows, macOS, and Linux environments.
