What is your favourite shell to use

Zsh works for me

Plus oh-my-zsh and the powerline 10k theme - this is my go-to shell.
- Pure theme ftw

Bash

Not because it's the best or even my favourite. Just because I create so many ephemeral VMs and containers that code switching isn't worth it for me.

Exactly, I choose the one that's always there on every machine I access!
Seconded. Having an awesome Fish setup doesn't help at all when you're constantly having to shell into other machines unless you somehow keep your dotfiles synced, and that sounds like a total hassle.

I'd rather my muscle memory be optimized for the standard setup.
- I use Ansible playbooks to keep my config in sync. It's great but there is a bit of a learning curve. Makes it easy to deploy config changes.

Definitely fish. It does everything i need out of the box. To achieve the same with zsh, i needed a dozen plugins on top of a plugin manager. Here, in satisfied with just Starship as custom prompt.

That said, i’ve been trying nushell recently. Don’t really think it’s for me, but it is pretty interesting

Zsh + oh-my-zsh

Uh. Whatever my distro comes with per default.

Honestly? Bash. I tried a bunch a few years back and eventually settled back on bash.

Fish was really nice in a lot of ways, but the incompatibilities with normal POSIX workflows threw me off regularly. The tradeoff ended up with me moving off of it.

I liked the extensibility of zsh, except that I found it would get slow with only a few bits from ohmyzsh installed. My terminal did cool things but too slowly for me to find it acceptable.

Dash was the opposite, too feature light for me to be able to use efficiently. It didn't even have tab completion. I suffered that week.

Bash sits in a middle ground of usability, performance, and extensibility that just works for me. It has enough features to work well out of the box, I can add enough in my bashrc to ease some workflows for myself, and it's basically instantaneous when I open a terminal or run simple commands.

Fish has continued to add bash compat over time.
while I still use ohmyzsh, a lot of it's opponents make it's slowness one of its complaints. You don't need ohmyzsh to have fancy things, it's just makes setting it all up a little easier.

I know I'm a heretic but I'm a huge powershell fan. Once you work with an object-oriented shell you'll wonder why you've dealt with parsing text for so long. Works great on Linux, MacOS and Windows, it's open source, reads and writes csv, json and xml natively, native web and rest service support, built-in support for remote computing and parallel processing and extensive libraries for just about anything you can think of. It takes a little getting used to but it's worth it.

TBH, I use Powershell on my Windows install, and they've made some good improvements over the years. I forget that it also works on Linux.

Shame v1.0 ships with new installations, and you have to manually go out and install the latest versions to get the benefits. Dunno why MS doesn't just automatically update it with everything else.
- Version 2 came with Windows 7. Version 5 comes with Windows 10 (and I think 11). V7 is the latest but being cross-platform doesn't come with some of the Windows-specific modules built into v5.
- V1 never actually shipped with any version of Windows
  
  Windows 7 shipped with V2, 8 with V3, 8.1 with v4, and 10 with v5 and later 5.1.
  
  5.1 is the latest (and last) version of Windows PowerShell.
  
  All versions after that are just PowerShell (or PowerShell Core for version 6)
  
  Not sure why they don't bundle it by default, but starting at v7.2 it can be updated by Windows update
I use powershell by default on windows and I prefer it for scripting any day of the week vs. shell scripts. It's not the fastest but you can always plug in .net to your scripts to dramatically improve performance. Sure, I could write the script in rust or whatever to make it even faster, but that's way more work than I need for the lifespan of the script.
Even on Windows I try to avoid Powershell. I use bash through GitBash there, too. But, I don't mind using Powershell for work, because some workflows are already implemented in ps1-scripts.

bash is so ubiquitous that I never considered anything else.

Don't try zsh, because you won't be able to go back to bash after that 😉

Fish for an interactive shell, and I'll often drop back to bash for writing a script. I can never remember how to do basic program flow in fish. Bash scripting is not great, but you can always find an example to remind you of how it goes.

Wait, I'm supposed to choose my favourite of the three shells?

Is that how they work??

zsh

My job is working with a ton of servers over ssh. Bash is the most convenient balance between features and not needing to do any setup.

Bash or ZSH. Whatever is default.

Bash is fine. Zsh on Macs is fine too. I can’t stress how useful it is to learn busybox if you end up with a shell on an embedded device.

All these crazy shells people talk about are kinda like race car controls. I’m not driving a race car, I’m driving a box truck with three on the tree.

nushell is excellent for dealing with structured data. it’s also great as a scripting language.

The PEPPPERONI of tools!? that's not a thing right? why pepperoni??

Because pepperoni rocks

Fish, less config and super easy to set things like path, colors, and the support for dev environments and tooling is better than it was. Used to be a Zsh user, but moved since I distro hop so dang much. Less time to get going.

I’m here for the colors :3 teehee

Soft shell tacos are my favorite. Hard shell is ok but there's nothing like a double wrapped soft taco.

Oh and I just use bash.

Pff, newbie. I bash my tacos!

/s

Former zsh user. fish works for me.
For scripts I use bash tho.

I've explained my choice for zsh here

Nicely configured it's so convenient that I spend most of my time in the terminal and don't even use a file explorer anymore. It can also be expanded with some plugins for specific use-cases.

You and me both.

zsh, because of highly customizable.

Eshell because it is consistent cross platform and I switch often for work/etc. Sometimes I’ll use bash when I really want a native shell.

I used fish before eshell and I really like it, the auto complete is nice, but eshell has autocomplete and since aliases and other configurations are in my emacs config, they sync cross platform too.

Fish, without a doubt.

How come?

Fellow Fish user here! 👋🏻

Zsh

No plugin manager. Zsh has a builtin plugin system (autoload) and ships with most things you want (like Git integration).

My config: http://github.com/cbarrick/dotfiles

Zsh, because unlike Bash using arrays in Zsh doesn't make me want to perform percussive maintenance on the nearest Von-Neumann machine

I always figured that Ksh / POSIX / Bash shell arrays are kept as they are because anyone with a serious need of arrays ought to be using something better than a scripting language.
- Not necessarily.
  They're a basic data structure used everywhere, most notably with command arguments ( $@ ) and can make shell scripts a viable option for many simple tasks if their syntax makes sense and you don't have to wonder how their expansion works every time you see one being used.

Bash, not because its my favourite but because it's nearly ubiquitous. I don't want to have to think about which shell I'm using.

POSIX shell. No, seriously. Works everywhere.

After that Python for usability.

I really like nushell, which has more of a feel and ergonomics of a modern programming language without the idiosyncrasies of traditional shells (so it's obviously not POSIX shell compatible).

One major downside is that it's not yet stable, so breaking changes between releases are expected.

ZSH through the excellent ZSH Quickstart Kit.

How have I been using zsh for this long yet never heard of that? I gotta give it a go, thanks!
- It's definitely a hidden gem. Enjoy!

I went through sh->csh->tcsh->bash

Fish shell. I switched to fish ages ago, back when I didn't know much bash scripting. Now I am just so used to it that I don't wanna switch back. Plus it just works.

Slowly trying to learn sh while using mostly bash. Convenience is nice and all, but when I encounter something like OpenWRT or Android, I don't like the feeling of speaking a foreign language. Maybe if I can get super familiar with sh, then I might explore prettier or more convenient options, but I really want to know how to deal with the most universal shell.

This is a good approach. I've always found it beneficial to learn "the standard things" than relying on a customized setup.

I've seen some people absolutely lost when they login to a system without 500 custom aliases on it..

OpenBSD's default public domain kornshell fork on OpenBSD, oksh (portable OpenBSD ksh clone) on Linux/MacOS/Other Unix. It has far fewer extensions than something like Bash (which I consider a positive) while being much faster (tested with hyperfine), and the extensions it does have are all useful (arrays, coprocesses, select, .* not expanding to . or .., pattern blocks, suspending of the whole shell).

Favorite would be a highly customized zsh.

fizsh (not fish) is what I actually end up using, as I can't be bothered to copy that config around and retune it for each machine. Gives me the syntactic sugar of zsh with common default options on by default, an OK default prompt, and doesn't break POSIX assumptions like fish. Also Installs quickly from the package manager without needing to run through the zsh setup each time - unlike oh-my-zsh. And if I still need customization, all the zsh options are still there.

Xonsh. For basic use (running CLI programs with arguments) it works like any other shell, and for other uses it has nice Python syntax (and libraries!). For example, I like not needing a separate calculator program, as I can do maths directly in the shell with an intuitive syntax.

Fish for interactive shell. “It depends” for scripting, but usually ends up Bash since it is the NixOS default.

I've recently migrated to nushell, I don't straight up recommend it because it's not POSIX compliant, so unless you're already familiar with some other she'll I would not use it.

That being said, it's an awesome shell if you deal with structured data constantly, and that's something I do quite often so for me it's a great tool.

Just looking at it briefly it looks a lot like PowerShell, any reason to use it over PowerShell?
- Never used PowerShell, so I didn't know that it was available for Linux nor open source, since from a quick search both of them seem to be true I guess there's no real reason since both are described very similarly.
- It's indeed a lot like powershell, but I found it to be much less painful to use for everyday tasks. I can't really put my finger on it, but powershell always felt very clunky and unpredictable to use. With Nushell, I can write pipelines that usually have the desired behavior on the first try. Also, its more convenient in so many different aspects that I can't go back anymore.
  
  The biggest downside is, that it hasn't had a stable release yet. While I haven't encountered any bugs yet, there are often breaking changes with new releases that may break your scripts.

Nushell

oksh

Bash. By default it might seem less featureful than zsh.. but bash is a lot more powerful and extensible than some give it credit for. It might be more complex to set it up the way you like it, but once you do it, that configuration can be ported over wherever bash exists (ie. almost everywhere).

Bash is my favourite one, second to it being Fish

I use mainly fish and occasionally nushell.

zsh because I've been using it since college and I don't like change

Bash, zshell, BusyBox....you don't really need anything else

Bash, just because everything else already uses it. That and bashisms have infected nearly all of my scripts as I clumsily bump into the limitations of POSIX string manipulation.

I have found some very fun things with sed branching patterns as a result of these limitations though...

https://www.gnu.org/software/sed/manual/html_node/Branching-and-flow-control.html

Zsh with powerlevel10k + a few plugins

POSIX on servers, thinking of switching to POSIX on desktop but that's a bit awkward

Bash is my login shell, but I have fish set as the default shell for alacritty

Bash as it is what I'm most familiar with. Having an eye out on the https://amber-lang.com/ that compiles to bash for future scripting purposes.

PowerShell, with zsh being a close second

xterm+zsh

I have been enjoying fish a lot over the last few months, but I generally try to use Bash, it makes cross-*NIX administration that much easier.

zsh with grml config because I'm too lazy to make my own config.

Fish & dash.

Microsoft copilot

PowerShell, because of autocomplete and shift+arrows select.

I often end up in ps because I'm more familiar with it. But only if I have to do some scripting or so.

While fish is easy to set up, I can't even be arsed to do that most times, so bash ends up being the one I use most.

https://elv.sh

At the moment I'm using zsh with powerlevel10k. But powerlevel10k is not really supported anymore, and seems to be basically on life support. While it still works for now, I have been thinking of switching over to fish. But the lack of posix compatibility is holding me back a bit.

Zsh on workstations. Bash on servers.

I have customized ZSH to be very similar to Fish

xterm, because shortcut keys do what they are supposed to.

Edit:

Bash because it's default.

xterm is not a shell
- Ah OK, Bash because it's default.
xterm is a terminal emulator, not a shell. Anything that produces a terminal-compatible text stream can be started as the first program.

e.g. xterm -e nano, assuming you have the nano editor installed, has no instance of a traditional shell (e.g. bash, zsh) running between the xterm and the editor, but the editor still works.

You could argue that makes the editor itself a shell of sorts, because it's interactive and you can do things with it, but it's still not the xterm that inherits that title.
- IDK if federations doesn't work, I already wrote to another response that I use Bash.
  Since the Amiga in the 80's I considered CLI windows and Shell as the same thing,because they kind of were on the Amiga, as there was only 1 shell, and a CLI window was also called Shell. But that was obviously a misunderstanding I just never got quite rid of.

Bash, yash and fish depending on what i do

Powershell, but heavily customized.

Why the downvotes? Ps is pretty good and it works well on Linux too.

I used zsh, urxvt and konsole. I do prefer zsh. Urxvt is nice too.

I think you're conflating shells and terminals.
- I said I prefer zsh. I used terminals like urxvt when I used window managers. Urxvt + zsh works fine. On kde I didn't mind using zsh + konsole. Hope that clears up.

Swisher sweets but backwoods works too

I don't really rate zsh personally. I find the additional features/syntactic sugar it adds are a poor tradeoff for lower portability. I also end up changing the settings in my zshrc to make it behave more like bash.
