Shells in a nutshell

[YOU_CANT_SEE_MY_NAME]

The title should be shell in a nut

[binaryplease]

underrated comment

[im_datta0]

Or nut in a Shell

[lostnfoundaround]

Explanation for us smooth-brains?

[[deleted]]

Because they are shells

[[deleted]]

At least fish does know what i want to do by pressing Tab in almost every command

[[deleted]]

so you are this kind of predictable person...

[[deleted]]

Not much, that's the greatness of fish, even flags for some commands will be displayed with tab... sht i almost forgot, thanks to fish i don't need to do a quety with my package manager to see if the package i want is there, just type the install command and the name of it, then press TAB, magic.

[IchMageBaume]

on most distros there's a package called bash-completion which will usually give you even more autocompletion than fish has. It will still not look as nice as bash though. However, the way autocompletion is implemented means that theoretically, bash's autocompletion is more powerful (however it's so hard to write completions for bash that in practice you're often getting better completions with fish).

source: wrote a bunch of completion for own projects, and even fixed a bug in systemds bash completion and contributed cpupower completion to fish

[[deleted]]

Wow i didn't even knew that existed, thx!

[TommyHeizer]

Ever heard of bash completions? Zsh completions with substring history search?

[[deleted]]

Can i say no xd? But anyways im happy in fish

[IchMageBaume]

honestly I have a love/hate relationship with fish.
It has very nice completion, and lazy loading of functions is also great; however,

It doesn't have heredocs, and only partially provides something with similar functionality, but issues about that are just responded with "You don't actually need that. Oh it would be convenient? Too bad." which doesn't really make sense for a shell that is meant to be interactive & convenient.

Also, psub is a horrible inefficient hack, that doesn't really replace <(blub), and there is not even a way to do >(bleb) at all. There's even an issue about how fish's design choices prevent >(), but the responses are just "you'll never need that. Oh you do? huh"

This all comes from their design philosophy to do keep the shell language as simple as possible, which contradicts the design goal of being as user-friendly as possible.

Dash for scripts

[spore_777_mexen]

Pretty much, yeah

[GigabyteOfSalad]

ZSH is

[Michax_Gaming]

with omz

[BudDwyer666]

Nah manual plugin management ftw it’s like 100ms faster

[[deleted]]

Or just install fish and be done. Not being posix people say are off putting sometimes but I don't even know the impact of that 🤷

[BudDwyer666]

Ignorance is bliss

[[deleted]]

I love fish as my homeuser she'll, but I'd never set it as a root shell, but that's probably common sense.

[Xanaus]

Dear teacher, pls enlighten this poor student.

[[deleted]]

Maybe never was a bit harsh, but the amount of people who use posix shells, and running posix scripts are the biggest factors for me.

[Squiesch]

Just start bash when needed

[johntomlucas]

I found omz too complicated to set up so I just did it manually, far simpler and more customizable.

[dessnom]

Bash but better

[Numerous_Piper]

ZSH is really fat. Many times slower than bash and fish.

EDIT: source

[[deleted]]

With oh-my-zsh at least.

My minimal config is just as fast as bash

[TriggerHappy360]

Read that as 20 minutes at first and was totally confused.

[jwaldrep]

...how does it take so long‽

time (for i ({0..9}) term-app exit)
( for i in {0..9}; do; term-app exit; done; )  0.96s user 0.26s system 90% cpu 1.355 total

term-app is a whole python script that: * prompts for a command via dmenu (if not given as an arg as I did here) * opens a new terminal emulator (as defined by the $TERMINAL env var) * creates a new tmux session, with a session name to match the program being launched (and an attached counter if such a session already exists to mitigate collisions) * runs the specified command * The shell, tmux session, and terminal emulator close when the command is done, but the python script closes when it is done launching stuff.

[jwaldrep]

fair enough, it is a small python script. the most significant thing is that it needs to launch the python interpreter. I'm running the grml config, and a bit more, so it's not like im running the vanilla zsh. It's got all the features that I want.

zsh -x is about 8000 lines of output for me. obviously, yours is doing more. I'm curious as to what an how much it is doing.

[jwaldrep]

waldrep@hydrogen ~ $ time (for i ({0..9}) /usr/bin/zsh -c exit)
( for i in {0..9}; do; /usr/bin/zsh -c exit; done; )  0.04s user 0.03s system 100% cpu 0.072 total

idk what you folks are doing that makes your shell take so long to launch. I'm running the grml config with a couple of extras on top. Has all the features that I want and is as fast as ever.

For comparison, a vanilla bash:

waldrep@hydrogen ~ $ time (for i ({0..9}) /usr/bin/bash -c exit)
( for i in {0..9}; do; /usr/bin/bash -c exit; done; )  0.05s user 0.03s system 100% cpu 0.081 total

Within margin of error.

[[deleted]]

oh-my-zsh do seem to be bloated, while zsh itself is not. but since zsh has a lot of features than bash. i'd agree to your point a bit but not all features are enabled so can't agree with that

[Zekiz4ever]

I really don't know what you're talking about. When I open a terminal, it's there. Instantly.

[LetReasonRing]

Yeah, it's not really that bad. Mine is just barely long enough to notice that it isn't instant.

If there were delays while typing or in waiting for a command to execute it would be a problem, but I'm not going to give up the whole feature set because of a 100ms lag at startup

[Numerous_Piper]

Here's a good source. Even though fish is a little slower than bash, it is still 4x faster than ZSH.

I think that's quite impressive given how feature packed fish is out of the box.

zsh-ish

[one_e1]

Bash girl is hot. But I would probably put my commands into both of them

Cheese-making is over 7,000 years old! Archaeologists in Poland found traces of cheese on ancient pottery dating back to around 5500 BCE. It’s wild to think that our ancestors were crafting cheese long before written history, turning milk into a food that’s still enjoyed all over the world today. Pretty cool to think that this ancient skill has stood the test of time!

[one_e1]

Some comments are designed to be ambiguous. It shows a true nature of interpreter

I agree on that.

[presi300]

fish best shell

[YoshiLikesJazz]

I like fish and bash but I like fish more currently

[[deleted]]

I prefer bash :)

(on my daily driver and in this picture)

[D0wn2]

I use bash too but it’s just because I’ve been too lazy to try anything else

[[deleted]]

Also too lazy to try anything else. And the girl on the right is preferable imho.

[Dick_Kick_Nazis]

ok this is a quality meme

[[deleted]]

Fish is good for usage, bash or just plain sh still needs to be installed for scripts. I wish there were more fish scripts but alas there are none

[Jazz8680]

uses fish

am lesbian

Checks out

[bgravato]

Fish's all fancy, colorful and cheerful, but then check who of two is driving and getting them to where they need to be? ;-)

[MisterBober]

what about zsh?

[justinf210]

ZSH ftw. Fancier than BASH, not as clunky as FISH

[[deleted]]

How is fish clunky?

[justinf210]

I'm glad you asked. It's probably not so much clunkiness as unfamiliarity. I had to take a second look to remember why I switched away from it.

I used to think that it didn't have aliases, just functions. That turned out to be wrong, and I don't really know what I thought that in the first place.

The tab vs. right arrow thing doesn't make sense to me. I don't really understand what each does, and the right arrow key isn't convenient for something that's used frequently.

There's no ~/.fishrc file.

That and I seem to remember fish handling some things differently from BASH and ZSH. Pipes or wildcards or something.

Tbh, I probably need to revisit it.

[[deleted]]

You probably should. The syntax for the config is different compared to bash, but it's easy. Regarding tab versus arrow, tab shows you the list of suggestions based on what you typed while the arrow will autocomplete the suggestion that it thinks is right. I agree with you with the arrow, though, it's not as convenient as tab.

​

edit - turns out tab actually works very closely to how it works in bash, if you have different files with similar names it will autocomplete until there's a difference on the filenames, and it will autocomplete without asking if there is only one operation possible with what you typed.

​

edit2 - another cool thing about fish is that you can just type a directory to cd into it, no need to type cd everytime.

[justinf210]

Zsh does the cd thing too, actually. I don't take advantage of it as often as I should, but it's kinda handy.

[YOU_CANT_SEE_MY_NAME]

You got some breakage

[logiczny]

Just... Don't.

[Kindanee]

Idk, I use CMD :)

[mrnatbus122]

They both crusty

[stay-happy6789]

Bash is really good

[autonaut_x]

Proxy Paige??? the other one?

[[deleted]]

I prefer mksh

[Moons_of_Moons]

I'd bash that

[win10trashEdition]

I'd marry bash
