Bash Defensive Patterns

This skill equips Claude with specialized knowledge for creating resilient shell scripts capable of handling errors gracefully and operating safely in production environments. It provides implementation patterns for strict mode execution, secure variable handling, robust argument parsing, and idempotency, ensuring that automation scripts—ranging from CI/CD pipelines to system utilities—are maintainable, portable, and fault-tolerant. By applying these patterns, users can prevent common pitfalls such as word splitting, silent failures, and resource leaks that frequently plague standard shell scripting.
