> Fish is also not POSIX which has always been its, and my, issue

Could you give some examples of issues you encountered because of that? I've been using fish for about 8 years now I can't remember an instance where that was a problem in interactive use.

Same here. More than 5 years with fish and it’s been like 5 times when not-POSIX was an “issue”, which I’ve been solving by temporarily entering bash and rerunning the command there.

Issue is the cognitive overhead to know 2 distinct shell languages. One you use, and one (almost) everyone else uses. If later isn't of your concern and Fish is all you interact with then no issue whatsoever for interactive or/and scripting use.

Not to be funny, but is POSIX scripting even still relevant? It's well understood that they should only be used for quick and simple tasks, and anything more serious or demanding should be done using something like python instead. But these quick and dirty tasks are very easy for LLM coding agents to do in python. I used to have dozens of shell scripts, each no more than tens of lines long, in my ~/bin/, but I had an LLM rewrite all of them in python, adding proper argument handling, --help messages and error handling too in the process. I sincerely don't think I'll ever write another bash script again.

I write all my scripts in bash. I'm not learning a new language.

That's not a problem since it's available and when #/bin/bash or env bash is there, it just works.

My bash scripts are stored in a folder on my PATH, so it all just works.

For me it’s always been an inability to “copy this command from stackoverflow” (or in the modern day, it’ll be copy this from ChatGPT) into your shell. Maybe it’s better now, but the last time I seriously gave fish a chance was 2014.

Also one of may main use case is documenting things other developers can do to make their life easier. There are handful of things where zsh behaves differently than bash. And while those handful of thins are not even a POSIX or shell things, they often come up.

The reality is, every day I’m fighting with “developers” who don’t know what the difference between AWS, Linux, and bash is. Throwing “fish” into the mix seems like I’m just being obtuse for no reason. I have sept hours trying to explain to some dumbass that git-bash on windows is not the same thing as Linux only for them to call me “oh he really cares about ‘bash’”-guy. While claiming they are “Linux developers” as they use macOS.

I confess I don't really get this. Fish and Bash are different languages in the same way that Ruby and Perl are different languages. And if I want to run a Perl script, I don't try to run it in a Ruby interpreter, and I don't get grumpy at Ruby for not being source-compatible with Perl.

Which is to say, if you need to run a Bash script, run it via `bash foo.sh` rather than `./foo.sh`. There's no need to limit yourself to a worse shell just because there exist some scripts out there written in that shell's language.
