From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I use nushell for my terminal/console (alacritty). For POSIX compability, mksh; I set it as SHELL so programs, which expect/assume POSIX, use it instead of nu. This is the way to have best of both worlds.
I've been eyeing nushell but it's such a departure from posix that it just never sticks. How did you make the switch?
It is because it departs from POSIX that it is good; I recognize the syntax for some functionality is cumbersome and hard to remember though. There are similarities like command names and piping still...
I use NixOS and home-manager, so for switching I just
home-manager.users.yuu = {
programs.nushell = {
package = pkgs-update.nushell;
enable = true;
configFile.source = ../../config/nushell/config.nu;
envFile.source = ../../config/nushell/env.nu;
};
};
The config.nu and env.nu is basically the default just with a customized prompt.
Then in my alacritty.ylm I set shell to the nu binary
shell:
program: /etc/profiles/per-user/yuu/bin/nu
Also learned from official resources https://www.nushell.sh/book. When I have doubts, I ask either on Nushell's GitHub discussions or https://matrix.to/#/#nushell:matrix.org
And to keep a POSIX shell
{
environment = {
systemPackages = with pkgs; [
mksh
];
sessionVariables = rec {
TERM = "alacritty";
TERMINAL = "alacritty";
SHELL = "${pkgs.mksh}/bin/mksh";
};
environment.shells = [
"${pkgs.mksh}/bin/mksh"
];
}
I'm a simple person, I see Nix I upvote.
Thanks for the comment, I may copy some stuff. :p
You're a person of culture as well I see; I upvote comments of culture yes📠
I remember talking with you at the NixOS matrix; nice to see you here as well💖✨✨✨🌠
It's true! Sometimes the internet seams really smoll.
Maybe one day I will actually understand the appeal of all these super fancy shells. They seem kinda cool on the surface but I also feel like I'd never use any of their actual features.
If Bash is your default shell, you can install Fish to try its superb auto suggestions and the tab key, while leaving Bash as your default shell. These auto suggestions do not only work for your command line history but also for file names even when your first letters you type are in different order in the file name (For example, I know that I want to edit a file with the word work in it and start typing the word work and press tab key, but it turns out that the word does start instead with the word personal, Fish is still able to suggest the real file name to edit : personal_and_work_todo.txt). Fish has saved me a lot of typing time. And if you need Bash for a moment (Fish will complain about certain * usage), then temporarily exiting Fish or typing bash is an option.
After installing Fish, run the fish_config command to configure it via a local session in your web browser.
But have you tried them?
I've actually used Fish on my old system. I didn't use it as daily driver. Now I've installed Manjaro, and it uses ZSH by default. And now I can compere them, and oh my, Fish auto-completion is way better. it's interactive, showing command names and help on them. and allow to select completion by arrows, not [Tab].
Only downside of fish is that it is incompatible with Bash. In Zsh you could copy-paste bash commands from tutorials and they would just work, but in Fish you need ot alter them, for example $(cmd) is just (cmd) in Fish.
Truthfully, I've not tried them.
I was about to make a comment along the lines of "I've already learned how to do command line things, my OS already comes with a few shells, why SHOULD I take the time to learn a new shell?"
but then I reflected on this and realized something: it's the same thing as saying "Windows comes with Explorer/Edge, why SHOULD I go through the trouble to pick up a new web browser?" And yet, I unquestioningly download Firefox first thing when I install a new OS, hmm.
You've made me think :]
Fish is slowly adding more POSIX syntax, e.g. $(cmd), export ENV_VAR=1 and CFLAGS=-02 make now work as you would expect.
WOW! Gotta install it again. I was actually planing on it. But was lazy.
I used dash as my /bin/sh due to it being a lot lighter & faster than bash.
Right now I'm trying out ion as my interactive shell and so far it works great.
Fish is cool tho.
None of these pique mine interest enough to try them, but I was surprised that the oil shell didn't make an appearance. Besides fish and nushell, it was the only alternative shell I'd heard of.
I'm a huge fan of nushell
I've been using fish for years, and highly recommend it. In particular, I find that fish has excellent contextual completion based on folder as well as great highlighting.
I tried and liked it a lot years ago. But the piping wasn't asynchronous so you have to wait the full completion of the first command for the next.
I'm not sure about the current state but if that is fixed I would happily fully switch.
Looks like the latest version streams output from one command to the other. For example, when I run for i in (seq 1 5); sleep 1; echo $i; end | cat I see the numbers show up one at a time.
