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.
