How does this improve script security?

It enforces variable quoting to prevent word splitting and glob expansion, and provides patterns for input sanitization and secure temporary file creation using mktemp.

Is this skill only for Bash?

While it focuses heavily on modern Bash patterns, it also includes POSIX-compliant alternatives for environments where Bash is not available.

Can this skill help with script portability?

Yes, it provides guidance on choosing between Bash-specific features and POSIX-compliant syntax to ensure your scripts run across different environments.

What is strict mode in shell scripting?

Strict mode (set -euo pipefail) ensures scripts exit immediately on errors, treat unset variables as errors, and catch failures in piped commands, preventing silent failures.

Can I use this for existing scripts?

Absolutely. This skill is ideal for reviewing and refactoring legacy shell code to improve its reliability, security, and maintainability.
