Basically every non-Windows system comes with a POSIX-compliant shell at /bin/sh. If you’re using shebangs in your POSIX shell scripts like you should, using Fish as your Friendly InteractiveShell shouldn’t be a problem.
even if it was… you can just run bash or /bin/sh and then run the script there. It’s not you can’t shell into a different shell to run a script. you lose nothing.
Don’t try to out-nerd me, your shebang advice isn’t even POSIX compliant ! Use #!/usr/bin/env sh, there are systems (incl. NixOS) where there is no /bin/sh
And Fish’s scripting language leaks into the interactive shell. Setting variables via export a=b doesn’t work, for example. I don’t like that.
Yes, it’s true that #!/usr/bin/env bash is a more reliable way to get bash, but you mentioned that you wanted a POSIX shell, not that you specifically needed bash, so #!/bin/sh will work on any system including NixOS.
Also, export a=bdoes work in Fish. But you don’t have to use it if you don’t know how it works.
I used to use fish but I don’t like their weird scripting language. I want my shell to be POSIX compliant.
Not being POSIX is one of its main selling points. If you want POSIX, you’re not the target audience
Thank you for rephrasing what I said.
