fish never claimed to be POSIX compliant to begin with, so no. There never was an 'extend' step.

All your existing scripts will continue to work just fine. #!/usr/bin/bash

Not restricted to fish shell, but I can further recommend starship.rs as a prompt, and using fzf to search through command history.

I used fish for a couple of years and really liked it. But I recently learned that I can configure ZSH to have all of the same auto-complete and plugins that I loved from fish. Now I have all of the creature comforts I like, with POSIX compliance

I found that while fish has better syntax than bash for most things, the hassles with incompatibility or unexpected behavior brought me much more trouble than BASH's syntax ever has

I used Fish for several years before switching over to nushell a few weeks ago.

Nushell takes the ideas behind Fish even further by incorporating types other than strings and adding more built-in functionality that’s useful for your average command-line user.

I doubt I’ll go back but both are great! Highly recommend Fish and Nushell!

Yeah, I mean they have the hashbang.

Fish really shines in interactive use, like being able to write fish_vi_key_bindings, and that setting is preserved after restarting fish. Or using funced and funcsave to modify helper scripts, or abbr -s ...

I'm not sure I've ever opened my fish config file, but I'm still able to customize it easily
