SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

Bash and POSIX shell scripts often suffer from silent failures, security pitfalls, and portability issues. This skill provides a robust toolkit to validate syntax and enforce best practices, helping teams ship safer, more reliable shell automation.

Core Features & Use Cases

  • Syntax validation with bash -n and sh -n, plus ShellCheck analysis for in-depth issues.
  • Security and portability checks, including detection of unsafe eval, unquoted variables, and bashisms in POSIX scripts.
  • Quick audits for CI pipelines, legacy scripts, and onboarding exercises; ideal for developers, sysadmins, and devops engineers.

Quick Start

Run the validator on your script: bash scripts/validate.sh path/to/script.sh to perform syntax, style, and security checks.

FAQPage Schema
How do I validate Bash scripts for syntax errors and security issues?

Validate Bash scripts by running the validator script, which uses bash -n and sh -n for syntax checks, plus optional ShellCheck analysis to detect unsafe eval, unquoted variables, and portability concerns.

What is the best way to check POSIX shell scripts for bashisms?

Check POSIX shell scripts for bashisms using a validator with custom portability checks that detect non-compliant syntax, enforcing strict mode and proper quoting to ensure scripts run across different POSIX-compliant environments.

Can I audit multiple shell scripts in a CI pipeline?

Yes, you can audit multiple shell scripts in a CI pipeline by running batch audits with the validator, which targets script files across development, CI pipelines, and automation tasks for on-demand syntax and security checks.

Does the validator require ShellCheck to be installed?

No, ShellCheck is optional for in-depth analysis. The validator performs syntax validation using bash -n and sh -n, along with custom checks for strict mode, proper quoting, and bashism detection without requiring ShellCheck.

Why should I enforce strict mode and quoting in Bash scripts?

Enforce strict mode and quoting in Bash scripts to prevent silent failures, security pitfalls, and portability issues. The validator checks for unquoted variables and unsafe eval to help teams ship safer, more reliable shell automation.
