Does this skill support modern Bash 5.x features?

Yes, it utilizes modern features like associative arrays and version detection while maintaining fallbacks for environments using older versions of Bash.

Can I use this for macOS-specific shell scripting?

Absolutely. The skill emphasizes POSIX compliance and includes logic to handle differences between GNU tools on Linux and BSD variants on macOS.

What makes a Bash script 'defensive'?

Defensive scripting involves using strict error handling, validating all inputs, implementing cleanup traps for temporary files, and quoting all variables to prevent injection or word-splitting errors.

How does this skill handle script testing?

It generates comprehensive test suites using frameworks like bats-core or shellspec, including mocking for external dependencies and TAP output for CI/CD integration.

Is the output compatible with linting tools?

Yes, all generated scripts are designed to be ShellCheck-clean and can include .shellcheckrc and .editorconfig files for consistent project standards.
