What is the best way to run ShellCheck on a large project?

The skill provides performance optimization patterns, such as using xargs for parallel processing or implementing local caching to speed up recurring linting tasks.

Can I use this to automate my GitHub Actions workflow?

Yes, the skill includes specific templates and configuration patterns for integrating ShellCheck directly into GitHub Actions and GitLab CI/CD pipelines.

Does this skill help with POSIX portability?

Absolutely. It provides specific configurations to enforce POSIX compliance (SC3000-SC3999), ensuring your scripts run reliably across different Unix-like systems.

Which shell dialects are supported by this skill?

The skill provides guidance for all shells supported by ShellCheck, including Bash, sh, dash, and ksh, with a focus on target-specific rules.

How do I handle recurring false positives in my scripts?

The skill demonstrates how to use in-line suppression directives and project-level .shellcheckrc files to disable specific rules without compromising overall script quality.
