What is Bash strict mode in this skill?

Bash strict mode refers to the 'set -Eeuo pipefail' configuration which ensures your script exits immediately if a command fails, a variable is undefined, or a pipe terminates with an error.

Can these patterns be used for CI/CD pipelines?

Yes, these patterns are specifically designed for CI/CD environments where silent failures can lead to broken deployments; they ensure scripts are loud and clear about errors.

Why does the skill emphasize variable quoting?

Quoting variables (e.g., "$VAR") is a critical defensive pattern that prevents word splitting and globbing, which are common sources of bugs and security vulnerabilities in shell scripts.

How does this skill handle script cleanup?

It utilizes Bash traps (ERR and EXIT) to ensure that temporary files are deleted and background processes are terminated even if the script crashes.

Implements robust, production-grade shell scripts using advanced defensive programming and error-handling techniques.

关于

This skill provides a comprehensive framework for writing fault-tolerant and reliable Bash scripts suitable for production environments. It focuses on implementing strict execution modes, systematic error trapping, and secure variable handling to prevent common pitfalls like word splitting or silent failures. By incorporating patterns for idempotency, structured logging, and safe temporary file management, it enables developers to build automation tools, CI/CD pipelines, and system utilities that are resilient, maintainable, and safe to run across diverse platforms.
