SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires python3, pip3, shellcheck, and includes scripts (resource) components.

What problem does it solve?

The Bash Script Validator addresses the reliability gap in Bash and POSIX shell scripting by checking syntax, running ShellCheck analyses, and surfacing common pitfalls before they reach production.

Core Features & Use Cases

  • Syntax validation using bash -n or sh -n to catch errors early.
  • ShellCheck-backed linting with configurable system or wrapper modes.
  • Custom checks for security, portability, and best-practice improvements.
  • Deterministic execution flow suitable for CI or local development.

Quick Start

Run the validator on a script to see syntax errors, ShellCheck results, and recommended fixes.

FAQPage Schema
How do I validate and lint Bash scripts for syntax errors and common pitfalls?▼

This validator checks Bash and POSIX shell scripts using bash -n or sh -n for syntax errors, then runs ShellCheck to surface common scripting pitfalls and recommended fixes before production deployment.

What is the best way to audit shell scripts for security and portability issues?▼

Auditing shell scripts for security and portability involves running custom checks alongside ShellCheck linting. This process identifies best-practice violations and compatibility issues across Bash and POSIX shells to improve script reliability.

Can I use this Bash script validator in CI pipelines with deterministic execution?▼

Yes, the Bash script validator supports deterministic execution flows suitable for CI pipelines. It applies syntax validation and ShellCheck analyses consistently across Bash and POSIX shells to catch errors before they reach production.

Does shell script linting require ShellCheck to be installed locally?▼

Shell script linting supports both system and wrapper ShellCheck modes, meaning you can use a locally installed ShellCheck dependency or a wrapper configuration to analyze your Bash scripts and surface common pitfalls.

How do I add custom checks for POSIX shell scripts to an existing validator?▼

You can extend checks for POSIX shell scripts by adding custom scripts to the extensible scripts directory. This allows you to enforce specific security, portability, and best-practice improvements beyond the standard ShellCheck linting.
