POSIX shell standards for Mark's workflow unify portable, defensive scripting practices to reduce errors and portability issues.
Audit an existing shell script and refactor it to strictly use POSIX sh, add the Unlicense header, and implement proper error handling.

Make a shell script portable by enforcing POSIX sh standards for shebangs, variable quoting, and error handling so it runs reliably on /bin/sh across Unix-like environments. Refactoring existing scripts ensures compatibility and reduces portability issues.
The best way to refactor a shell script to be POSIX compliant is by applying consistent error handling, standardizing variable naming conventions, and running shellcheck-based linting to identify non-portable syntax for reliable cross-shell execution.
You need to use POSIX sh instead of Bash when scripts must run reliably across diverse Unix-like environments without Bash-specific dependencies. Bash is only acceptable with explicit justification for features unavailable in standard POSIX sh.
Shellcheck works with POSIX sh scripts to improve error handling by linting code for defensive scripting practices. It identifies non-compliant syntax and enforces consistent quoting practices to increase reliability and maintainability for portable shell scripts.
A limitation of using POSIX sh is the lack of arrays and advanced string manipulation found in Bash. For complex scripting requiring these features, Bash is acceptable but requires explicit justification and careful documentation for cross-shell compatibility.
