How does this skill handle script cleanup?

It provides templates for using 'trap' signals to ensure temporary files are deleted and background processes are terminated safely, even if the script crashes or is interrupted.

What is Bash Strict Mode?

Bash Strict Mode uses 'set -Eeuo pipefail' to ensure scripts exit immediately on errors, undefined variables, or pipe failures, preventing bugs from cascading silently.

What is idempotent script design?

It is a pattern included in this skill that ensures a script can be run multiple times without causing side effects, such as checking if a directory exists before attempting to create it.

Is this skill suitable for CI/CD pipelines?

Yes, it is specifically optimized for production environments like GitHub Actions, Jenkins, or GitLab CI where script reliability and predictable failure modes are critical.

How does it improve variable safety?

The skill enforces strict quoting and parameter expansion patterns to prevent common issues related to spaces in filenames, empty variables, and unintended globbing.

Provides production-grade defensive programming techniques and patterns for creating robust, error-resilient shell scripts and automation workflows.

关于

Bash Defensive Patterns is a specialized skill designed to help developers write safer, more reliable shell scripts for system administration, CI/CD pipelines, and infrastructure automation. It implements the 'Unofficial Bash Strict Mode,' enforces variable quoting, and provides robust patterns for error trapping, temporary file management, and idempotent design. Whether you are building complex deployment scripts or simple utility tools, this skill ensures your shell code can handle edge cases, prevent silent failures, and remain maintainable across different environments and platforms.
