As you may have noted from previous posts in this Advent 2023 series, I find myself using Bash more and more often. This has certainly been a surprise for a career PHP developer, but it is what it is.

With PHP, there are a wealth of QA tools, from unit testing, to enforcing coding standards, to static analysis. What about with Bash? Well, the tools exist, and there's one I literally cannot write Bash without: Shellcheck.
