      Prints out what shell you’re using. Bash is default for most Linux distros. MacOS switched from bash to zsh as their default. Zsh is hella customizable, by default it functions more or less like bash.

      Fish is cool, has neat quality of life features out of the box, but can also break scripts sometimes.

    Default zsh is just bash, you need to add all the fancy plugins to get it to do cool stuff

    fish is for people who don’t want to spend the time setting it all up and to just get a shell that has most of the QoL fetaures builtin.

          No, they are executed according to the shebang on the first line, which is usually bash. If it is missing, it will default to the current shell.

            That’s true, but I definitely use fish as my default shell and when it runs a script without shebang it automatically runs it with bash. Thus I assume that’s the fish default to make your scripts work.

          You don’t even need a proper shebang. Scripts without shebang are executed in bash by fish.

        I tried switching to Nushell but certain things just wouldn’t work so I switched back to zsh. sha512sum wouldn’t work and there’s no native replacement.

            The main differentiator of fish over everything else is it prioritizes intuitive behavior over backwards compatibility.

            Zsh is to bash as c++ is to c. Most bash scripts and habits will work in zsh, but zsh is just more convenient and has more options. Fish is intentionally different.

            Do I wish fish had existed instead of bash so we had a nicer terminal experience? On the whole, yes. But I also couldn’t be bothered to learn another shell where most of the instructions online won’t be able to help you, and I ended up sticking with zsh.

            Be aware that fish isn’t a POSIX-compatible shell enough, so you have to adjust syntax.

              That isn’t incorrect, but it’s not as important as people make it out to be. Linux isn’t certified as POSIX-conformant either.

              People are way too stuck on POSIX regarding Fish specifically, but in shell scripting, POSIX compliance boils down to “can it run a pure sh script”. Bash is compliant. Zsh is partially compliant and needs to set an option to emulate sh. Fish uses a different syntax and is not compliant; if that is a problem, don’t execute sh scripts in Fish.

              POSIX compliance for shell scripts was important in the 80s and 90s when the #! directive wasn’t as commonly implemented and every script might be executed by the user’s $SHELL instead. That is no longer the case as virtually every Unix-like system’s program loader supports #!.

                I use fish, but sometimes it acts weird. And lots of “just copy and past this command” kind of online solutions I have to put into bash.

                It’s a cool shell, I use it as a daily driver (though I’m keeping a close eye on elvish which syntactically is even further away from classic shell), but the comments read like fish is basically zsh. And while zsh is pretty close to bash, fish isn’t.

            This is a good way of putting it. It’s essentially ZSH with Autosuggest/complete and a theming agent. At least visual-wise.

            When you get into the scripting and the hot keys aspect of it, they reinvent the wheel and everything is different., Like for example ,!! and other bangs(I think that’s the right word?) like that are not valid on fish, And everything to do with variables is different from adding to your path to setting variables to creating functions. Also checking your error code is going to be different as well as it doesn’t follow the $x style inputs and doesn’t support IFS and globbing works differently.

            TLDR; fish is nice, but If you use it unless you want to relearn an entire type of language, keep your scripts on bash or zsh

            or if you wanna see the bigger differences fish has a dedicated bash transition page

              I never managed to learn bash’s ways in my first decade of using it, learning fish a decade ago was easy by comparison. So much more human readable and sensible and consistent. Even though fish is the friendly interactive shell, I now use it for all my scripting too.

                That was the exact opposite with fish. I had already gotten fairly well first with bash by the time I started using it, and the way fish did it was just super counterintuitive to me.

                I couldn’t get into the overall design of how it looked and I disliked how command substitution and the built in’s worked, Combined with the fact that it’s a lesser used shell, so there’s less information available on it. I just couldn’t do it.

                You brought up a point though. That makes me ask. You must not have to share your scripts with anyone then, right? Fish has a very small user base in comparison to ZSH and Bash and when I make a script that’s more advanced I tend to want to share it with my friends and having them install a whole new shell just to run a script is just not helpful to me. ZSH is close enough to bash in compatibility that, generally speaking, if I want to share it, I can use zsh And then convert the minor discrepancies. Where with fish I have to redo the entire script.

            Yup, very similar! And quite customizable as well if you want to. But the focus is on having, by default, a friendly interactive shell.

            I like that I can spin up a VM, install fish, chsh and I’m all set.

      Fish is great if you can’t remember a specific command, or don’t want to type out long filenames/locations, but I dunno if I’d use it as the default.

      I just type “fish” in the terminal if I ever run into a situation where I might get some use from it.

        in my ~/.bashrc

        # if interactive, launch fish
[[ $- != *i* ]] && return || fish

        and

        alias f='fish'

        So fish is my default, and if I ever need bash, it’s already there underneath, just a Ctrl-d keybind away to fall back on, and if I want to get back into fish, it’s just a f & RETURN away.

        Seems better to have all the convenience of fish up front. All the completion magic. I so rarely have to type much at all.

              I’m guessing, you mean this then: https://github.com/edc/bass

              But well, I was rather thinking of when it’s using Bash-scripting-syntax to combine multiple commands.
              Like, maybe there’s a for-loop in there. You just can’t paste that directly into Fish and have it work. Granted, you should probably put that into a script file, even if you’re using Bash, but yeah, just temporarily launching bash is also an option.

      I jumped from bash to fish because cachy os has it as default. I kinda don’t like it, it’s a little too fancy, but it’s not bad enough for me to bother switching the default to bash. So I’m using it. Still not quite liking it but maybe it’s growing on me.

    I have never really ever used bash and thought, "Man, I wish my shell was better . . . ". Using ctrl+r to recall past commands, using sudo !! to fix missing permissions and writing small bash scripts all work very well.

    That being said, if you use anything else, and you like it, I’m happy for you, but I do wonder, what leads people to other shells? What problems do they have with bash?

      I switched to zsh at a time where completion for commands parameters except file paths in bash wasn’t really a thing, you could add some with a script, but they didn’t work well. I’m sure the situation has improved by now, but someone told me recently, there are still no descriptions for the completions. I find it very helpful and it saves me opening a man page a lot of times. For example, typing grep -<Tab> gives me this: 8167

      And now I’m so used to many little features (mostly around the syntax) that wouldn’t be a reason to switch on their own, that I find bash cumbersome to use.

      To me, it genuinely makes a huge difference that I don’t have to manually press Ctrl+R for history search. Because 9 times out of 10, I accept a history suggestion from Fish where I did not think about whether it would be in my history.

      This includes really mundane commands, like cd some/deeply/nested/path/. You would not believe, how often I want to cd into the same directory.
      But I’ve also had it where I started typing a complicated docker run command and Fish suggests the exact command I want to write, because apparently I already ran that exact command months ago and simply forgot.

        Yep, and fish has even more ways to expedite frequent used commands and locations, but because the completion stuff’s so good, it’s easy to never bother setting up abbreviations and keybinds and so on. So many things are often just a couple key presses away, by default, after using it for a while.

      I script everything in bash, but for everyday use fish just has some modern QoL things that make it easier to get around. For me, specifically, it’s the way you can recall commands by seeing a ghost version of your history, as you type. You can even scroll through a filtered history if you’re part-way through typing some long command that matches what you have typed.

      Another neat thing, it does it’s best to predict what I want to type and remembers common locations, showing them as ghost text as well.
