Apart from the other good stuff in this release, I think this will make a lot of things much easier: fish now supports && (like and), || (like or), and ! (like not), for better migration from POSIX-compliant shells

That’s new? Suddenly I feel less guilty about dodging coworkers who have been trying for years to get other people to try fish. But maybe now it’s getting closer to production readiness.

Fish uses (and still supports) `command1; and command2` instead of `command1 && command2` (and similarly for `||`/`or` and `!`/`not`).

The syntax is different, the semantics are the same.

Something I've been thinking about this week as a vanilla bash user: Does Fish (or zsh, or others) have the ability to maintain some sort of a global command history? I often find myself wanting to run the same command in multiple terminals and currently just copy-paste.

Iterm2 on osx supports sending the same inputs to multiple tabs

I've been happily using fish for maybe two years now, just as a default shell and not doing anything fancy. Out of the box it is great. I'm not sure how to feel about only now learning its indexes start at a [1] though (╯°□°）╯︵ ┻━┻ Love it otherwise.

Starting at 1 is good for non-programmers, who IMO could benefit the most from switching to Fish. I would love to see a distro using Fish as the default shell for non-root users.

When I’ve been teaching people to program, explaining [0] has been a tragic experience.

Starting at [0] is not objectively better than [1]. I actually believe it is objectively worse.

Long time zsh user here. Any reason one should try out fish?

At the very least it is a very well designed piece of software. Even if only for that reason, I would recommend taking a look.

Let me know when it's posix compliant.

Not part of a shell but in MacTerm the “command line” window has its own history and it can optionally send the text to all open windows.

I made fish my default shell for around a month, and I really liked the smart suggestions of what command I was going for when I started typing. But the "vi" mode had enough incompatibilities that it really irritated me, it was extremely incomplete. Discussions of it with devs went nowhere. Plus, there were incompatibilities in the language that I could never bring myself to commit to memory; I might have if the vi m…

ZSH seems to have broader community support and there's a plugin for basically everything. This is why I chose to stick with it over Fish.

If I just wanted a very simple shell, with good defaults, I'd choose Fish. But much like why I use (Neo)Vim I prefer the DIY approach and have gotten my ZSH to the point over the years (and a hundred scripts later) where I love it.

But ZSH the language is pretty awful and non-intuitive (although way better than bash when you dig into it). Even though I've been writing it for years I still get it mixed up often.

My hope is that Evlish shell will be mature enough soon to use day-to-day, which is the only one I've seen with a modern scripting language (written in Go) and is 10x faster than my ZSH (which is very noticeable): https://elv.sh

The sort of global history you want is possible with bash: https://news.ycombinator.com/item?id=3755276
