shell-script-safety

What problem does it solve?

Bash scripting often suffers from unsafe quoting, inadequate error handling, and sloppy variable hygiene that lead to bugs and security vulnerabilities. This Skill provides practical, scalable guidelines and patterns to enforce safe scripting practices across projects.

Core Features & Use Cases

• Strict mode guidance: recommends using set -euo pipefail and traps for cleanup to catch errors early.
• Quoting discipline: demonstrates when and how to quote variables and arrays to prevent word splitting and glob expansion.
• Injection prevention: advises on avoiding eval and constructing commands safely with arrays and proper parameter handling.
• Real-world examples: shows common anti-patterns and their corrected forms.

Quick Start

Run a shell-script safety review across your Bash scripts to enforce best practices.
