What is the benefit of implementing a dry-run mode?

Dry-run support allows you to preview destructive actions—like file deletions or server reboots—without executing them, which is critical for testing scripts in production environments.

Why should I use strict mode in Bash scripts?

Strict mode (set -Eeuo pipefail) ensures your script exits immediately when a command fails, a variable is undefined, or a pipe fails, preventing silent failures that lead to corrupted data.

How does this skill improve CI/CD pipelines?

It provides patterns for idempotency and error trapping, ensuring deployment scripts fail safely and don't leave your infrastructure in an inconsistent or half-configured state.

Why is variable quoting so important in shell scripts?

Proper quoting prevents 'word splitting' and 'globbing,' which occur when variables contain spaces or special characters, leading to unexpected behavior or security vulnerabilities.

Does this skill help with script portability?

Yes, it includes patterns for safe directory detection and conditional logic that helps scripts run reliably across various Unix-like systems and shell versions.

소개

This skill equips Claude with a comprehensive framework for writing resilient Bash scripts, moving beyond simple command execution to production-ready automation. It enforces industry-standard best practices such as strict mode activation, sophisticated error trapping, and rigorous variable quoting to eliminate common shell pitfalls. By utilizing these defensive patterns, developers can ensure their CI/CD pipelines, system utilities, and deployment scripts are idempotent, handle edge cases gracefully, and include essential production features like structured logging and dry-run capabilities.
