Shellcheck Configuration
A solid reference for getting ShellCheck properly configured in your projects. Covers the practical stuff like setting up .shellcheckrc files, integrating with CI pipelines, and handling the most common error codes you'll actually encounter (SC2086 for quoting issues, SC2181 for exit code checking, SC1091 for sourced files). Shows you how to suppress false positives without going overboard, configure pre-commit hooks, and optimize performance when checking multiple scripts. The error code explanations with before/after examples are genuinely helpful when you're staring at cryptic ShellCheck output at 2am trying to fix your deployment scripts.

ShellCheck Configuration and Static Analysis
Comprehensive guidance for configuring and using ShellCheck to improve shell script quality, catch common pitfalls, and enforce best practices through static code analysis.
When to Use This Skill
- Setting up linting for shell scripts in CI/CD pipelines
- Analyzing existing shell scripts for issues
- Understanding ShellCheck error codes and warnings
- Configuring ShellCheck for specific project requirements
- Integrating ShellCheck into development workflows
- Suppressing false positives and configuring rule sets
- Enforcing consistent code quality standards
- Migrating scripts to meet quality gates
Detailed patterns and worked examples
Detailed pattern documentation lives in references/details.md. Read that file when the navigation tier above is insufficient.
Best Practices
- Run ShellCheck in CI/CD - Catch issues before merging
- Configure for your target shell - Don't analyze bash as sh
- Document exclusions - Explain why violations are suppressed
- Address violations - Don't just disable warnings
- Enable strict mode - Use
--enable=allwith careful exclusions - Update regularly - Keep ShellCheck current for new checks
- Use pre-commit hooks - Catch issues locally before pushing
- Integrate with editors - Get real-time feedback during development
