Does this skill support shells other than Bash?

Yes, it provides guidance for Bash, Zsh, and POSIX-compliant shell scripting to ensure maximum portability across different Unix-like systems.

How does this skill improve script security?

It enforces critical security practices such as proper variable quoting, input sanitization, and avoiding dangerous commands like 'eval' to prevent injection vulnerabilities.

What is 'Strict Mode' in shell scripting?

Strict Mode refers to using 'set -euo pipefail', which ensures scripts exit immediately upon command failure or when encountering unset variables, preventing silent and dangerous failures.

Can this skill help with processing JSON or YAML in scripts?

Absolutely. It includes specific patterns and best practices for using modern tools like jq and yq to safely parse and manipulate structured data within shell environments.
