ShellCheck is a static analysis tool for shell scripts that identifies syntax errors, semantic problems, and common pitfalls in bash, sh, dash, and ksh.

Can this skill help with POSIX compliance?

Yes, it provides configuration patterns and specific error code resolutions to ensure your scripts adhere to POSIX standards for maximum portability.

What is the benefit of using a .shellcheckrc file?

A .shellcheckrc file allows you to define project-wide rules, enable optional strict checks, and ignore specific warnings consistently across all contributors' environments.

How do I suppress specific ShellCheck warnings?

You can suppress warnings by adding a comment like '# shellcheck disable=SCxxxx' directly above the problematic line or at the top of the script for global suppression.

How do I automate ShellCheck in my workflow?

This skill provides templates for Git pre-commit hooks, GitHub Actions, and GitLab CI pipelines to automatically lint your scripts during development and deployment.

開発者ツール

Configures and implements ShellCheck static analysis to identify bugs, improve portability, and enforce best practices in shell scripts.

概要

This skill empowers Claude to act as a shell scripting expert, specializing in the configuration and application of ShellCheck for static code analysis. It provides comprehensive guidance on setting up project-level linting using .shellcheckrc, interpreting specific error codes (SC1000-SC3999), and integrating automated checks into CI/CD pipelines. By leveraging this skill, developers can catch common pitfalls like improper quoting, non-portable syntax, and logic errors before they reach production, ensuring robust and maintainable automation scripts.
