Writing Scripts

Choose Python for cross-platform compatibility, complex logic, and API integration; use Bash for system-level tasks, performance-critical scripts, and direct shell operations. This Skill provides a decision matrix matching task complexity, platform requirements, and performance needs to the right language.

Error handling in automation scripts requires language-specific patterns: Python uses try-except blocks and exit codes; Bash uses set -e, trap handlers, and conditional checks. This Skill provides detailed patterns for both languages to catch and recover from subprocess failures.

Subprocess management requires input validation, proper escaping, and error capture. This Skill covers subprocess best practices including safe string escaping, dry-run modes, and automatic backup setup to prevent accidental data loss.

Debugging subprocess errors involves isolating language-specific failures, validating inputs, and testing in safe environments. This Skill enforces safety-first practices with dry-run support and structured templates for reproducible script execution.

Cross-platform automation requires choosing languages and patterns carefully. Python offers better portability; Bash works natively on Unix-like systems. This Skill guides language selection and provides platform-specific implementation references.

Robust automation scripts need consistent structure for error handling, logging, and safety checks. This Skill provides templates with proper setup, input validation, subprocess management, and backup mechanisms built in.
