Bash Defensive Patterns

소개

This skill provides a comprehensive library of defensive programming patterns and best practices for writing robust, maintainable Bash scripts. It equips developers with the tools to handle common shell scripting pitfalls through strict execution modes, advanced error trapping, and safe variable handling. By integrating patterns for idempotent design, atomic file operations, and structured logging, it transforms fragile scripts into production-ready automation suitable for CI/CD pipelines, deployment workflows, and complex system administration tasks.
