Another advantage of fish is that the grammar is decidable (and in fact it is LL(1) ), unlike POSIX shell which is undecidable (with aliases being the most common cause), and implemented slightly differently by each shell in practice when aliases and interpolation happens. It is actually possible for a mere mortal to sit down and write their own parser for it In particular, fish commands deal with arrays of strings instead of interpolating whitespace separated strings everywhere, and there is no text-based alias, only function definitions that are good enough so that defining a text-based alias is not necessary

You can do anything from this video in zsh (though it will require a lot of configuring, especially if you're like me and refuse to use Oh My Zsh because it's bloat), with the added benefit that zsh is POSIX compliant and you can use it for scripting.
how to add the listing of available flags to zsh? as in 2:03 - nevermind, found it, but it does not look half as nice as in fish
4 ปีที่แล้ว +7
@X GNU Bio Do you know what POSIX compliant means? It means that it runs any script that is written according to the POSIX standard. Zsh will run any such script. Bash also. But Fish won't. Of course, both bash and zsh have features that go beyond the POSIX standard. But that is only an added bonus, not an problem (because the entire POSIX standard is covered). However, on fish you can run only scripts written for fish, and nothing else. On zsh and bash you can run any POSIX compliant script, plus the scripts written specifically for bash and zsh, respectively.

@@gaweyn On Arch Linux install the package "zsh-completions" and add the following to your .zshrc: zstyle :compinstall filename '/home/yourusername/.zshrc' autoload -Uz compinit zstyle ':completion:*' menu select zstyle ':completion:*' matcher-list 'm:{a-zA-Z}={A-Za-z}' zstyle ':completion:*' rehash true zmodload zsh/complist compinit For more details, how to customise colours etc, RTFM. You can make it look as good as on fish. Find a good example of a .zshrc online and just steal from it. Or use Oh-My-Zsh, if you're a total nôôb.
I love fish for interactive auto-completions and other sophisticated stuff, but so far I have 2 annoying things with it: 1. (slightly annoying) Delete key deletes characters to the end of line and then begins to delete backwards, like backspace. 2. (very annoying) There is some issue with re-rendering active line. It's a little bit hard to describe. If you just type some command, even a long one with parameters, or navigate through history and run it as is, everything works fine; but if you pull a line from history and star editing it, use auto-completion or switching between normal and insert modes, it will mess up the current command line. Does anyone had those issues and found any solution?
this is a completely extreme level that i really want to be able to use, but I'm such a noob, the idea of using a git as your origin just completely blew my mind, im over here trying to consolidate my storage and keep backups and thinking about portable install, and its like, ultimate portable system would obviously be keeping the basic stuff network attached, I knew there was a lot to learn about linux but jeez, this rabbit hole goes all the way down to the moon
I also used fish and was happy with it for interactive use, but it is not compatible with bash, e.g. interpolation works differently. Therefore one needs to make sure it is only used for interactive use, which is a pain. I switched to zsh / oh-my-zsh and am really happy with the choice.
There's really no need to use oh-my-zsh. It's bloated af. Just put the plugins in some folder and source them from .zshrc. Same goes for themes. And you can just put all the aliases you need in one file and source that as well. And they are also other less bloated plugin managers for zsh, e. g. zplug
I was using up to the day I had to sftp from one machine into the other and fish didn’t detect it wasn’t an interactive session. It displayed a long welcome message crashing sftp. Went back to zsh
Took me a very long time to consider using fish, as I didn't know enough about Linux in general. But then I found bass: wiki.gentoo.org/wiki/Fish#bass bass "...executes a given command in bash and then transfers updated environment variables back into fish." 😎 And yeah I know; I linked to the Gentoo Wiki. Don't be scared. Sure, I know most people aren't a level-IV-Linux-Neckbeard like me, but even if you're running Linux Mint, I assure you that with nothing more than manpages, Arch and Gentoo wikis, you'll have all the information you need. Damn-well near all the Linux information in existence.
There's a faster and a bit more advanced highlighting compared to the standard for zsh out there. Worth checking out: github.com/zdharma/fast-syntax-highlighting
Fish is great. But some things just don't work in it, I guess it has ventured just too far away from the posix standard to be compatible with everything. I'll stick with zsh because otherwise I would have to use two different shells, fish and zsh/bash for stuff that doesn't work in fish.
That's what most fish user do, they stick with fish for interactive use and a posix-compliant shell for scripts, fish is made for interactive use and not scripts, it hasn't ventured away from being posix compliant, it doesn't want to be posix compliant, you can check it all in the fish website.
@@aedd3307 Well then it didn't reach its goal to make things simpler, if you need to remember to use () in fish and $() in scripting, or set VAR 123 in fish, VAR=123 in scripting. That just doesn't make sense and it makes things more complicated.
I agree about reserving Fish for interactive use. I would personally _never_ script in it. I've always approached ZSH this way too. I like to keep scripts as portable as I can, so SH if it can be done in SH, BASH syntax if I need it, and I usually switch to Python if it gets to be too ugly/impossible in BASH.
There are two things I really didn't like about fish when I was using it (now I use zsh): 1. Renaming $() to (). With that, they removed the possibility of the posix () to e.g. pipe the output of multiple commands into one, e.g. `(cat test.txt; journalctl -xe | grep "123") | lolcat` (there are more complex examples where you can't replace it easily with process substitution but I wanted to make something simple) Also $() does make more sense to me, because the functionality is very similar to $variable, where it also kind of parses the output inline instead of writing it to stdout like () does. 2. Having a web browser builtin. Yeah, this may be useful for many people, but I don't want it and it's a shell running a useless web server on my computer. If it was something separate that just edits the fish config files, I would be totally fine with it. I had some other complaints, but it's been like a year or so since I switched to zsh and I don't really know everything anymore.
I agree, I also didn't like the change to `end`, I think it's pretty arbitary, you can just remember one thing (spelling the initialization keyword backwards) in posix sh and it's not really simpler to use end then.
It doesn't have a webserver built in. What `fish_config` does is run a small script written in Python. Assuming you're running a Debian derivative like Ubuntu, you can find the script at /usr/share/fish/tools/web_config/webconfig.py.
There is a shell that I would like to redirect you to called FIZSH (Friendly Interactive Z Shell), which is a front end to ZSH with interactive syntax-highting and Matlab-like history search (like fish), while still being POSIX compliant. github.com/zsh-users/fizsh
fish has one problem: most of the things on the web work mostly for sh/bash/zsh so fish will always be a niche case. I started using fish and just changed to oh my zsh and i dont miss it at all. you should too.
Exactly what I did! In isolation, Fish was great. But I'm not always just on my machine. I want to get used to the same commands that would likely work everywhere. That's part of why we love using the terminal in the first place. :-)
I've noticed a weird quirk in Fish: I have figlet set to display my name whenever I open my terminal in my config.fish Whenever I execute a shell script, figlet displays at the beginning of the script, meaning that Fish re-executes the configuration file when a script is ran? It's quite annoying, and I can't find a way to fix it.
can somebody please tell me what the difference or relationship between a DE and a SHELL is ... yeah Im thinking of moving one of my machines over to Linux , but first I need to learn a bit about Linux.
A DE is the whole desktop experience. This could include the login screen, and the window manager and quite a few other things. The way shell was explained to me is "the language of the terminal" which I don't fully understand yet. Edit: I'm still quite new too. Just got my first Arch install done a couple days ago
I too want to move to Linux. But haven't bit the bullet yet. I'm hoping to start using a Linux alternative to PowerShell while I'm still using Windows, so when the time comes to switch, it is not so painful. Your question is difficult to answer. A shell is actually the interpreter of the commands that you are typing in into the command line. While normal programming languages like C# and Java are designed to be used to write programs, a shell language like bash or fish or zsh is designed to so that you can execute single lines of code to interact with your computer, so they will be terse. if you are asking about the term "desktop environment" when you say "DE", then that is the graphical user interface loaded by Linux which you would use to launch other apps. A bit like a launcher for Android. It would also have defaults for things like what app is used for what, like the terminal, package manager etc. As for the relationship between the two, they are both ways of interacting with your computer, one text based, and one graphics based.
Is there a Posix 32 compliant fork of fish? I like many of the features, but I don't use the terminal just for MY system, but I do scripts for all my devices and servers, also systems for other people, so having a non compliant shell doesn't do me a favor.
I quit zsh after noticing that the only plugins I used were actually built into fish. And man, starship is damn fast. I might just finally stop hopping between utilities and settle down for a while
Dracula theme, idk about the other stuff. It's transparent and probably running in alacritty. The stuff at the start with the pacman and fish is probably some program like neofetch running when he launches a fish shell.
Hi DistroTube, I really liked your video :) I have been using Fish and I was not aware of omf. I installed omf and I installed the theme called sashimi as I personally think it looks the best. However there are two things that I wish to change about it. 1) if I am in lets just say ~/Desktop/testing, it would show _testing_ only. I wish it would show the file file path like it does on bash. Is there a way to change this? 2) In your video we can see if you are in insert mode or normal mode, for some reason that doesn't show on my fish shell, what did you do to configure this?
Fish isn't POSIX compliant, which becomes annoying very quickly. This is why after finding fish, I switch to zsh along with plugins (installed via antibody) to get the main features of fish.
I just started learning and someone has remote acces to my computer using fish they have disabled my computer from downloading or from allowing me to install virtual environments can someone help me out how to get acces too my root to be able to block them please
If you remove every instance of "fish" from the video you won't be able to figure out if he is talking about zsh or fish; most things are also possible in zsh as well plus zsh you can add or remove features. Are there any unique good things about fish? Except you don't have to configure things like you would with other shells.
Yes. Fish is faster than zsh to redraw the prompt and run scripts in, especially if you install oh-my-zsh for zsh. Not sure what you mean by "removing features" because fish is already rather minimal except for syntax highlighting, which I guess (not sure) you can disable too. The zsh language is way too feature-rich - main reason why it's slow to run - and often times zsh metacharacters get in the way of actual commands (for example `git diff stash@{1}`). The fish language is far more minimal and it's designed with user-friendliness in mind (user-friendliness is the main selling point of the shell as a whole) and as a result, the syntax *never* gets in the way with commands. As an example, in fish you can run `find -name '*blah*' -exec foo {} +` without escaping anything as I just did.
@@brainplot Removing features I mean plain zsh doesn't look as well as fish but you get to pick plugins (even without oh-my-zsh which is bloat) that allows you to customize zsh and basically work the same as fish. I just tried fish and it is REALLY fast compared to my zsh at launch time. Do you think the shell will still be faster after all the configuration and plugins?
@@angli6939 I don't know from first-hand experience because I only have OMF installed for the theme that I use, which is bobthefish. Honestly I don't know which plugins you would install because the shell is already very smart by itself. That said, your needs may differ from mine.
It's almost one year I've been using Linux, always used default shell bash, so I don't know the difference between all these shell. Can anybody help me to understand the difference between all these shell's??
A shell is just the interface you type commands into. Bash is the bourne again shell it's a gnu project and basically a rewrite of an older shell and it is ment to add a bunch of features and modernise what is essentially the default Linux shell. Then there is zsh (my favourite) it adds a bunch of features (like sane prompt scripting, interactive tab completion and more!) The only reason it's not more popular is that you need to work for a config (very little is activated by default). Zsh also has a wide variety of plugins (oh my zsh ). A lot of them can match or even extend some of the things that fish has on by default. Fish (the one discussed) is by far the easiest to use and frankly I am not sure why Ubuntu is not using it by default (I mean it can't be used a login shell (all this means is that your system cant use it to run programs in startup) ) fish is easy and nice to use and it's sane! One of the problems with fish is that it's not POSIX complient (this means it does not conform to Unix standards set back in the 80s?) This makes the scrips you write less useable to others (portable) and means that fish may have a harder time using scripts written in other shell languages. There are others like csh (for c programmers) and ksh (I have no clue) but those arme a little more niche (I will also mention sh this is a faster but less feature rich shell used mostly for scripting). That's most of the differences imo.
@@debanjanbarman7212 it's an old standard for the way Unix systems work. It's mostly the syntax of the shell. POSIX is much more than that but that's what most people mean when they bring it up
Thanks fo rthe vi in bash comment. I thought this was possible, but didn't know. I appreciate your keyboard centric videos. I hope to try the keyboard centric display managers soon.
I would love to see how you would solve chroot or jail for ssh users but also for sftp. Can fish be used for sftp clients like filezilla or winscp? I need to move away from cpanel hosting and moving to containers with bind mounts with sftp with restricted shell for running composer, node, etc.
Have a look at kakoune. It's kind of like fish for Vim. In the sense that it takes the essence of what it does and reimagines what it does, having a lot saner defaults and good features. I recommend just reading the "why kakoune" page on their site to get an impression of how it compares to vim and what it does.
Thanks for this vid DT. Im just starting to learn scripting. Do you think it’s a good idea for me to just learn fish syntax since it is a bit different? I really like that it comes preconfigured with plugins.
No, I think you should start learning posix sh (or bash, which is posix sh with additional features). You probably don't want to script in fish, it's just made for interactive use. Thus I wouldn't recommend fish at all, because it makes things harder for your because you have to and posix sh syntax for scripting and in addition fish syntax for interactive use, which can result in you typing $() in the fish all the time, which is quite annoying.
what got me is ">>" not sure how to do equivalent . echo "hello world">>sometextfile.txt when i tried at least this didn't work. what is most missed with this is &>/dev/null
Ion think that you should do a full video on fish shell and omg because a lot of people do not know how to setup and change the setting files and put in alias
i might actually switch to fish.. i have a zsh config working now that i like but if i can reduce my config even further with fish and its sensible defaults then i think i'll try it people say it's bad becuz it's not posix-compliant but u can just use a shebang to get around that, or just switch to bash for scripting
I've always wondered what is the purpose of PowerShell outside Windows. I get names as "ls" or "cat" aren't intuitive or descriptive but "Get-ChildItem" is both a mouthful and annoying to type.
@@Gabifuertes Although there's some reasoning behind the syntax in PowerShell, I must say that it could be rethought and improved. The interesting idea is the concept of objects inside the shell. (And I am not talking about object oriented programming where you create classes, etc. [I don't think that is useful in a shell]). What I want to express is , we all know command like wc, sed, awk, etc to manipulating strings, are very useful. Even more useful is Manipulating objects in the shell. Imagine pipeping and displaying results only by selecting some properties of your first content. I am a Linux fan and I like the concept of objects oriented shell. I hope that someone else does something better than PowerShell. Currently it's the only one.
I’ve used both powershell and bash. I love Linux and bash. Linux is the best operating system to play around with. However having spent time learning some of both shells. PowerShell is definitely the better shell

Fish is great. I've been using it for years. I couldn't use any other shell at this point.
Another advantage of fish is that the grammar is decidable (and in fact it is LL(1) ), unlike POSIX shell which is undecidable (with aliases being the most common cause), and implemented slightly differently by each shell in practice when aliases and interpolation happens. It is actually possible for a mere mortal to sit down and write their own parser for it
In particular, fish commands deal with arrays of strings instead of interpolating whitespace separated strings everywhere, and there is no text-based alias, only function definitions that are good enough so that defining a text-based alias is not necessary
You can do anything from this video in zsh (though it will require a lot of configuring, especially if you're like me and refuse to use Oh My Zsh because it's bloat), with the added benefit that zsh is POSIX compliant and you can use it for scripting.
how to add the listing of available flags to zsh? as in 2:03 - nevermind, found it, but it does not look half as nice as in fish
@X GNU Bio Do you know what POSIX compliant means? It means that it runs any script that is written according to the POSIX standard. Zsh will run any such script. Bash also. But Fish won't.
Of course, both bash and zsh have features that go beyond the POSIX standard. But that is only an added bonus, not an problem (because the entire POSIX standard is covered).
However, on fish you can run only scripts written for fish, and nothing else. On zsh and bash you can run any POSIX compliant script, plus the scripts written specifically for bash and zsh, respectively.
@@gaweyn On Arch Linux install the package "zsh-completions" and add the following to your .zshrc:
zstyle :compinstall filename '/home/yourusername/.zshrc'
autoload -Uz compinit
zstyle ':completion:*' menu select
zstyle ':completion:*' matcher-list 'm:{a-zA-Z}={A-Za-z}'
zstyle ':completion:*' rehash true
zmodload zsh/complist
compinit
For more details, how to customise colours etc, RTFM. You can make it look as good as on fish. Find a good example of a .zshrc online and just steal from it. Or use Oh-My-Zsh, if you're a total nôôb.
Have you tried zplug? It's the new hotness.
@@LaurenZou nope. I'll look into it, but I'm fairly happy with my manual config.
I love fish for interactive auto-completions and other sophisticated stuff, but so far I have 2 annoying things with it:
1. (slightly annoying) Delete key deletes characters to the end of line and then begins to delete backwards, like backspace.
2. (very annoying) There is some issue with re-rendering active line. It's a little bit hard to describe. If you just type some command, even a long one with parameters, or navigate through history and run it as is, everything works fine; but if you pull a line from history and star editing it, use auto-completion or switching between normal and insert modes, it will mess up the current command line.
Does anyone had those issues and found any solution?
this is a completely extreme level that i really want to be able to use, but I'm such a noob, the idea of using a git as your origin just completely blew my mind, im over here trying to consolidate my storage and keep backups and thinking about portable install, and its like, ultimate portable system would obviously be keeping the basic stuff network attached, I knew there was a lot to learn about linux but jeez, this rabbit hole goes all the way down to the moon
I also used fish and was happy with it for interactive use, but it is not compatible with bash, e.g. interpolation works differently. Therefore one needs to make sure it is only used for interactive use, which is a pain. I switched to zsh / oh-my-zsh and am really happy with the choice.
Try oh my fish
There's really no need to use oh-my-zsh. It's bloated af. Just put the plugins in some folder and source them from .zshrc. Same goes for themes. And you can just put all the aliases you need in one file and source that as well. And they are also other less bloated plugin managers for zsh, e. g. zplug
@@konstantink07 Thanks for the suggestion, I never thought about optimizing this and was quite happy with my setup. I will look into zplug, too.
I’ve used fish for as long as I can remember using Linux. Thanks for reviewing this shell.
WHAT? A web browser config tool built-in?? Beautiful!
YES DT! I've been on fish for almost a year and its SICK
It's not just for Linux and macOS (Darwin) btw. I know it from GhostBSD, a FreeBSD distro. And it works on many other OSs, such as Illumos :)
I was using up to the day I had to sftp from one machine into the other and fish didn’t detect it wasn’t an interactive session. It displayed a long welcome message crashing sftp.
Went back to zsh
Brilliant! This is exactly the type of thing I've been looking for...
If you are using zsh and like the syntax highlighting in fish, there is a pretty cool plugin called zsh-syntax-highlighting
Danny Foldager Thomsen Very nice plugin.
is it as good?
@@room641A I haven been using fish that much too really tell difference. But I like it.
@@dannythomsen allright tanks ! il move to zsh and use that plugin
Took me a very long time to consider using fish, as I didn't know enough about Linux in general. But then I found bass:
wiki.gentoo.org/wiki/Fish#bass
bass "...executes a given command in bash and then transfers updated environment variables back into fish." 😎
And yeah I know; I linked to the Gentoo Wiki. Don't be scared. Sure, I know most people aren't a level-IV-Linux-Neckbeard like me, but even if you're running Linux Mint, I assure you that with nothing more than manpages, Arch and Gentoo wikis, you'll have all the information you need. Damn-well near all the Linux information in existence.
This comment felt so cringey
I loved Fish! But many of its commands were so different than others, I decided to lean in to zsh with “oh my zsh” instead.
Agreed I use the same, but fish is sexy af. I'm so tempted.
Better use zplug, it's far less bloated
@@konstantink07 better use zinit, it's even less bloated

Hey what are you using to generate those pacman / space invaders / etc. logins?
I finally found it, it's on his GitLab: gitlab.com/dwt1/shell-color-scripts
Fish is great. But some things just don't work in it, I guess it has ventured just too far away from the posix standard to be compatible with everything. I'll stick with zsh because otherwise I would have to use two different shells, fish and zsh/bash for stuff that doesn't work in fish.
This!
That's what most fish user do, they stick with fish for interactive use and a posix-compliant shell for scripts, fish is made for interactive use and not scripts, it hasn't ventured away from being posix compliant, it doesn't want to be posix compliant, you can check it all in the fish website.
@@aedd3307 Well then it didn't reach its goal to make things simpler, if you need to remember to use () in fish and $() in scripting, or set VAR 123 in fish, VAR=123 in scripting. That just doesn't make sense and it makes things more complicated.
I agree about reserving Fish for interactive use. I would personally _never_ script in it. I've always approached ZSH this way too. I like to keep scripts as portable as I can, so SH if it can be done in SH, BASH syntax if I need it, and I usually switch to Python if it gets to be too ugly/impossible in BASH.
Exploring the linux universe with DistroTube👀
you also can have that vi-mode indicator in bash.
There are two things I really didn't like about fish when I was using it (now I use zsh):
1. Renaming $() to (). With that, they removed the possibility of the posix () to e.g. pipe the output of multiple commands into one, e.g.
`(cat test.txt; journalctl -xe | grep "123") | lolcat` (there are more complex examples where you can't replace it easily with process substitution but I wanted to make something simple)
Also $() does make more sense to me, because the functionality is very similar to $variable, where it also kind of parses the output inline instead of writing it to stdout like () does.
2. Having a web browser builtin. Yeah, this may be useful for many people, but I don't want it and it's a shell running a useless web server on my computer. If it was something separate that just edits the fish config files, I would be totally fine with it.
I had some other complaints, but it's been like a year or so since I switched to zsh and I don't really know everything anymore.
I agree, I also didn't like the change to `end`, I think it's pretty arbitary, you can just remember one thing (spelling the initialization keyword backwards) in posix sh and it's not really simpler to use end then.
I would add the setting variables in fish is horrible.
It doesn't have a webserver built in. What `fish_config` does is run a small script written in Python. Assuming you're running a Debian derivative like Ubuntu, you can find the script at /usr/share/fish/tools/web_config/webconfig.py.
@@talideon Oh well, you are right, it's not really built in, I confused it with cups where it is builtin.
I have everything I need in Zsh, I don't see differences at all.
Oh My Zsh! Yes.
@@csbnikhil I don't use Oh My Zsh. Everything manually.

moxy weird cpu buy okay
only thing keeping me from switching is that "sudo !!" doesnt work. im sure there's a way to implement it though
This is a shell I might actually try, though the non-POSIX will definitely take some getting used to. Thanks for the tour.
There is a shell that I would like to redirect you to called FIZSH (Friendly Interactive Z Shell), which is a front end to ZSH with interactive syntax-highting and Matlab-like history search (like fish), while still being POSIX compliant. github.com/zsh-users/fizsh
Been using Fish for about a year. Not changing anytime soon!
Thanks for this I'm just learning Linux and this is a must have imo.
Fish has a web configuration for previewing and configuring themes and such.
Will never replace Zsh with Oh My Zsh.
Fish has Oh My Fish which is pretty darn similar.
@@semilin I've seen it, yeah.
I am a user of Zsh and Oh my Zsh and can understand that as well. You just get addicted to it...
@Him God I hope so
I tried fish and I also like Zsh with Oh My Zsh more.
I personally prefer zsh, as I like to configure things myself and be able to customize it, as opposed to having a fancy sell like fish out of the box
Hello guys, how to colorized output "ip a" or "ifconfig" on fish shell?
fish has one problem: most of the things on the web work mostly for sh/bash/zsh so fish will always be a niche case. I started using fish and just changed to oh my zsh and i dont miss it at all.
you should too.
Exactly what I did! In isolation, Fish was great. But I'm not always just on my machine. I want to get used to the same commands that would likely work everywhere. That's part of why we love using the terminal in the first place. :-)
Why is neovim your default editor instead of emacs, which you've done some videos on?
have you tried `fizsh`?
I've noticed a weird quirk in Fish:
I have figlet set to display my name whenever I open my terminal in my config.fish
Whenever I execute a shell script, figlet displays at the beginning of the script,
meaning that Fish re-executes the configuration file when a script is ran?
It's quite annoying, and I can't find a way to fix it.
can somebody please tell me what the difference or relationship between a DE and a SHELL is ... yeah Im thinking of moving one of my machines over to Linux , but first I need to learn a bit about Linux.
A DE is the whole desktop experience. This could include the login screen, and the window manager and quite a few other things. The way shell was explained to me is "the language of the terminal" which I don't fully understand yet.
Edit: I'm still quite new too. Just got my first Arch install done a couple days ago
I too want to move to Linux. But haven't bit the bullet yet. I'm hoping to start using a Linux alternative to PowerShell while I'm still using Windows, so when the time comes to switch, it is not so painful.
Your question is difficult to answer. A shell is actually the interpreter of the commands that you are typing in into the command line. While normal programming languages like C# and Java are designed to be used to write programs, a shell language like bash or fish or zsh is designed to so that you can execute single lines of code to interact with your computer, so they will be terse.
if you are asking about the term "desktop environment" when you say "DE", then that is the graphical user interface loaded by Linux which you would use to launch other apps. A bit like a launcher for Android. It would also have defaults for things like what app is used for what, like the terminal, package manager etc.
As for the relationship between the two, they are both ways of interacting with your computer, one text based, and one graphics based.
You sound like Eugene from TWD. Keep up the good videos ✌️
Wow, thanks! Eugene is the man!
How does he do that pacman colourful greeting whenever he open a terminal?
Zsh is my favorite. Auto suggestions is SO helpful
Is there a Posix 32 compliant fork of fish? I like many of the features, but I don't use the terminal just for MY system, but I do scripts for all my devices and servers, also systems for other people, so having a non compliant shell doesn't do me a favor.
DistroTube: because my home directory is a git repository
Me: surprised pikachu
Amazing video man
I love your manner of speech. Idk if it’s an accent or that combined with your idiosyncratic speech characteristics. Where are you from?
Been using fish since 2015 when I got my first developer job 🙂 I love it!
Ta Mr D, am gonna give this a go as I have never heard of it, it doesn't matter how long you use Linux there are always new things to learn..kudos
Yep. Seems like Fish + Starship is enough for replacing a tons of things and hours in zsh, evenmore bash :D
I quit zsh after noticing that the only plugins I used were actually built into fish. And man, starship is damn fast. I might just finally stop hopping between utilities and settle down for a while
Can someone tell me the name of his theme colors and how or what to use to get the pacman and fish stuff on top on terminal start?
Dracula theme, idk about the other stuff. It's transparent and probably running in alacritty. The stuff at the start with the pacman and fish is probably some program like neofetch running when he launches a fish shell.
always good to explore other shells. I don't know if it offers anything that would make me switch to fish.
Auto completion

Jonathan Blow's shell: finally a shell that won't break my computer LOL
Hi DistroTube, I really liked your video :) I have been using Fish and I was not aware of omf. I installed omf and I installed the theme called sashimi as I personally think it looks the best. However there are two things that I wish to change about it.
1) if I am in lets just say ~/Desktop/testing, it would show _testing_ only. I wish it would show the file file path like it does on bash. Is there a way to change this?
2) In your video we can see if you are in insert mode or normal mode, for some reason that doesn't show on my fish shell, what did you do to configure this?
Grandpa said if a fish is bloated, toss it overboard
Hey, just wanted to know. Do you run fish as your default terminal or only as your interactive terminal?
Fish isn't POSIX compliant, which becomes annoying very quickly. This is why after finding fish, I switch to zsh along with plugins (installed via antibody) to get the main features of fish.
I just started learning and someone has remote acces to my computer using fish they have disabled my computer from downloading or from allowing me to install virtual environments can someone help me out how to get acces too my root to be able to block them please
Backspace doesnt wirk in vim with fish, it works with bash
If you remove every instance of "fish" from the video you won't be able to figure out if he is talking about zsh or fish; most things are also possible in zsh as well plus zsh you can add or remove features. Are there any unique good things about fish? Except you don't have to configure things like you would with other shells.
Yes. Fish is faster than zsh to redraw the prompt and run scripts in, especially if you install oh-my-zsh for zsh. Not sure what you mean by "removing features" because fish is already rather minimal except for syntax highlighting, which I guess (not sure) you can disable too.
The zsh language is way too feature-rich - main reason why it's slow to run - and often times zsh metacharacters get in the way of actual commands (for example `git diff stash@{1}`). The fish language is far more minimal and it's designed with user-friendliness in mind (user-friendliness is the main selling point of the shell as a whole) and as a result, the syntax *never* gets in the way with commands. As an example, in fish you can run `find -name '*blah*' -exec foo {} +` without escaping anything as I just did.
@@brainplot Removing features I mean plain zsh doesn't look as well as fish but you get to pick plugins (even without oh-my-zsh which is bloat) that allows you to customize zsh and basically work the same as fish. I just tried fish and it is REALLY fast compared to my zsh at launch time. Do you think the shell will still be faster after all the configuration and plugins?
@@angli6939 I don't know from first-hand experience because I only have OMF installed for the theme that I use, which is bobthefish. Honestly I don't know which plugins you would install because the shell is already very smart by itself. That said, your needs may differ from mine.
Thanks a lot! I'm happy with fish-shell ! :)
It's almost one year I've been using Linux, always used default shell bash, so I don't know the difference between all these shell. Can anybody help me to understand the difference between all these shell's??
medium.com/almoullim/from-bash-to-zsh-to-fish-e432f1e1b9f8
A shell is just the interface you type commands into. Bash is the bourne again shell it's a gnu project and basically a rewrite of an older shell and it is ment to add a bunch of features and modernise what is essentially the default Linux shell.
Then there is zsh (my favourite) it adds a bunch of features (like sane prompt scripting, interactive tab completion and more!) The only reason it's not more popular is that you need to work for a config (very little is activated by default). Zsh also has a wide variety of plugins (oh my zsh ). A lot of them can match or even extend some of the things that fish has on by default.
Fish (the one discussed) is by far the easiest to use and frankly I am not sure why Ubuntu is not using it by default (I mean it can't be used a login shell (all this means is that your system cant use it to run programs in startup) ) fish is easy and nice to use and it's sane! One of the problems with fish is that it's not POSIX complient (this means it does not conform to Unix standards set back in the 80s?) This makes the scrips you write less useable to others (portable) and means that fish may have a harder time using scripts written in other shell languages.
There are others like csh (for c programmers) and ksh (I have no clue) but those arme a little more niche (I will also mention sh this is a faster but less feature rich shell used mostly for scripting). That's most of the differences imo.

@@debanjanbarman7212 it's an old standard for the way Unix systems work. It's mostly the syntax of the shell. POSIX is much more than that but that's what most people mean when they bring it up

I would love to see how you would solve chroot or jail for ssh users but also for sftp. Can fish be used for sftp clients like filezilla or winscp? I need to move away from cpanel hosting and moving to containers with bind mounts with sftp with restricted shell for running composer, node, etc.
I love fish. I like to ask if you don't mind: why using aliases over abbreviations?
Have a look at kakoune. It's kind of like fish for Vim. In the sense that it
takes the essence of what it does and reimagines what it does, having a lot
saner defaults and good features. I recommend just reading the "why kakoune"
page on their site to get an impression of how it compares to vim and what it
does.
Well I think that the stuff about fish is not really sane, especially $(), which looks to me as they didn't really understand why it's $() and not ().
How do I get a dark theme on the fish configuration webpage like that?
Witch desktop are you using in this video ?

Thanks for this vid DT. Im just starting to learn scripting. Do you think it’s a good idea for me to just learn fish syntax since it is a bit different? I really like that it comes preconfigured with plugins.
No, I think you should start learning posix sh (or bash, which is posix sh with additional features). You probably don't want to script in fish, it's just made for interactive use. Thus I wouldn't recommend fish at all, because it makes things harder for your because you have to and posix sh syntax for scripting and in addition fish syntax for interactive use, which can result in you typing $() in the fish all the time, which is quite annoying.
Once U good with bash, what's the point? I guess binging through syntax of a new app without glancing at man? Not sure.
I was expecting that the command for color would actually do what it says, instead of standard white-on-black.
the changed syntax .. that means that most scripts won't run on it. not sure if that is a good thing.
what got me is ">>"
not sure how to do equivalent .
echo "hello world">>sometextfile.txt
when i tried at least this didn't work.
what is most missed with this is
&>/dev/null
also fish's math is easily replace with calc.
Ion think that you should do a full video on fish shell and omg because a lot of people do not know how to setup and change the setting files and put in alias

GOOD ONE
I've always wondered what is the purpose of PowerShell outside Windows. I get names as "ls" or "cat" aren't intuitive or descriptive but "Get-ChildItem" is both a mouthful and annoying to type.
@@Gabifuertes Although there's some reasoning behind the syntax in PowerShell, I must say that it could be rethought and improved. The interesting idea is the concept of objects inside the shell. (And I am not talking about object oriented programming where you create classes, etc. [I don't think that is useful in a shell]). What I want to express is , we all know command like wc, sed, awk, etc to manipulating strings, are very useful. Even more useful is Manipulating objects in the shell. Imagine pipeping and displaying results only by selecting some properties of your first content. I am a Linux fan and I like the concept of objects oriented shell. I hope that someone else does something better than PowerShell. Currently it's the only one.
I’ve used both powershell and bash. I love Linux and bash. Linux is the best operating system to play around with. However having spent time learning some of both shells. PowerShell is definitely the better shell
Gabifuertes I’ve spent time learning both bash and powershell. The “verb-noun” syntax is easier to memorize than the bash syntax
