What is 'Strict Mode' in shell scripting?

This skill implements the 'set -euo pipefail' configuration, which ensures scripts exit immediately on errors, undefined variables, or hidden failures within command pipelines.

Does this provide a starting template for new scripts?

Absolutely, it includes a comprehensive boilerplate with standard headers, argument parsing (getopts), logging functions, and cleanup routines to jumpstart professional script development.

How does this skill improve shell script security?

It enforces practices like input sanitization, avoiding 'eval' for user-provided data, and using secure temporary file creation via 'mktemp' to prevent common injection and race condition vulnerabilities.

Can this skill help with cross-platform compatibility?

Yes, it provides specific guidance on choosing between POSIX-compliant syntax for maximum portability and Bash-specific features like arrays and advanced tests when appropriate.

소개

This skill provides a comprehensive framework for writing high-quality shell scripts that are maintainable, secure, and portable. It guides Claude to implement strict error handling using flags like 'pipefail', ensures proper variable quoting to prevent word splitting, and offers standardized templates for complex logic such as argument parsing, logging, and cleanup traps. Whether refactoring legacy scripts or building new automation tools, this skill ensures that shell code adheres to industry-standard best practices and avoids common security pitfalls across Bash and POSIX environments.
