Cross-Platform Scripting

Overview

Cross-platform scripting targets Windows, Linux, and macOS with minimal behavior differences.

Strategy

• Prefer portable runtimes such as Python for shared logic
• Isolate OS-specific behavior in adapters
• Detect platform at runtime when required
• Use normalized path handling and encoding

Practical Example

import platform

if platform.system() == 'Windows':
    shell = 'powershell'
else:
    shell = 'bash'

Production Example

Build pipelines commonly run test and packaging scripts on multiple runners to validate platform compatibility before release.

Common Pitfalls

• Assuming path separators are identical
• Using OS-specific commands in shared scripts
• Ignoring locale and encoding differences

Key Takeaways

• Cross-platform scripts require clear separation of shared and OS-specific logic.
• Automated validation on multiple environments is essential.
• Portable tooling reduces environment-specific failures.
