i am using ZSH cause Fish is not POSIX compliant,which made it annoying to run scripts without rewriting them.
#!/bin/sh
Hope this helps
how about if its not in a sh file,its common for scripts to use sh or bash instead. but am just gonna stick to ZSH anyways
Linux doesnโt generally use extensions to decide what shell to use, so it doesnโt matter if itโs an sh file or not.
If it uses bash of course you can substitute #!/bin/bash
And of course you can use whatever shell you want, just saying that POSIX-compliance is not really relevant since the script can specify what shell it needs.
The file extension doesn't matter much on Linux. If you've got a shebang at the top, the shell you're running from will invoke the correct shell according to the shebang.
In some situations, you may want to use something like bash <your-script>, but that would only be when you've got a script that doesn't have a shebang, but not having one is bad practice and you really should be using them. Fish isn't the only non-POSIX shell you're going to encounter on a Linux system. Python, Perl, and probably some others will be there, and using a shebang ensures no shenanigans. So whether or not you use Fish, you should always use shebangs.
When is this a problem? What scripts don't use a shebang and/or why does using sh call fish instead of bash or dash?
I have a mild dislike of fish because a few substitutions are different enough that my muscle memory isn't there. (But I also haven't put in serious effort to learn them.)

I use fish because it was the default in cachyos and decided to give it a fair shake. I like the built in syntax highlighting and fancy autocomplete but I miss bash scripting and built in commands that replace standard commands can be weird sometimes. I have not tried scripting fish, to lazy to learn yet another scripting language, especially if bash is the (almost) de-facto standard.
You can always just continue using bash scripting, with a bash shebang in your scripts, if you miss it
That's what I do. Fish is great as interactive shell, scripts don't benefit that much from it and I can use what's familiar.
I've been using it for awhile now for the same reason, and think I'm going to switch back to sh as it has too many suggestions which I read and it interrupts my thoughts and slows me down.
I like having fish as an option, but don't think I'd ever use it as my default.
If I have a long command that uses long filenames, or I don't remember the syntax of something, I can just type "fish" and it'll open up a fish shell.
I've never understood the need for fish. The shell experience is basically the same as zsh, and although it's much more pleasant to script for, you miss out on compatibility with POSIX-compliant snippets, and besides, if you're writing long and complicated scripts that need anything more than a handful of scalar variables you should probably be using Python (or Perl if you're an old-school masochist).

friend brought me some seashells
When I installed freeBSD for the first time, I was so confused when !! didn't work.
Heh. Good stuff.
More! ;D I want to see all the shells, characterised so.
... Fish [over[1]]user here. Ooh, good burn. LOL.
[1: Not just user. Overuser. I do most of my scripting in fish. Think that's not overuse yet? ... I even wrote my own text editor in fish.]
