I'm working on a bash script for building containers using Podman on my M2 MacOS, but my server runs Alma Linux RHEL 9.5. I'm encountering some issues with a command meant to start a Postgres instance—it's behaving differently on each OS. Particularly, the variable replacement techniques I use work in one version of bash but not the other. I want to know how I can write bash code that will be compatible across both platforms in the future. Should I consider switching to another language like fish, or just run everything in containers to bypass MacOS discrepancies?

You can install a newer version of bash on your Mac using Homebrew. Just run `brew install bash` and you'll have a more recent version that can help standardize behavior across systems. Also, check out shellcheck for debugging your scripts—it highlights potential issues in your code!
