@wladyx I use it for all my scripts and as a daily shell. The only exception are the videos where I do now use it for setup scripts but not as shell, mainly to make instructions useful for everyone.
I think it's great! Was always wondering if it's possible to pass typed data through a pipe, so that shell autocomplete is not as blind as it usually is. Do you know if types of returned data items can be specified upfront, or everything is a 'table'? It would be cool if tables are also more specifically typed and autocomplete can take advantage of that information to give more adequate suggestions.
There are quite a few data types Nushell uses. You can see what a specific output is by piping it to `describe` (e.g. `ls | describe`). You can see the data types at www.nushell.sh/book/types_of_data.html.
True. Powershell was cursed by being Windows only (or Windows first) but it had (and still has) some great ideas and I can see some of them in Nushell.
I use PowerShell about 90% of the time on Linux for this reason. What do you like better about Nushell's approach? My biggest gripe is completion support, but a lot of CLI frameworks in Go and Rust now support creating PowerShell completions automatically.
@@elovelan To be honest, I haven't used Powershell in a long while. I used it briefly almost 20 years ago when it was released and discarded it. I don't remember it in details. Back then, it was Windows-only so that was the main reason why I did not jump on it. I should give it another try.
@@DevOpsToolkit I definitely like that Nushell feels much more similar to POSIX-like shells. However, I do find PowerShell worth the learning curve since I find its code more readable and thus more maintainable (at the expense of a lot of verbosity). I've been working in Bash since the mid-2000s and I still sometimes struggle to remember some of the more terse replacement syntax.
@@DevOpsToolkit Not necessarily a better swing. PowerShell (dubbed pwsh) is OSS and cross platform. Pipes are essential but instead of strings (what you call text) its now an object (what you call data) and thus has properties so a full blown language. This has been like this for quite a few years, so the demo is not surprising, its more, what took so long for this to happen ? The get-hyperscale examples is basically a PowerShell function that is available in memory. The .nu files are just functions in a .ps1 file.

I suspect similar to how Get-Help that exists in pwsh. I would actually challenge you, now that all IDEs come with some sort of AI coding assistant, spend 2 weeks with only pwsh.

I'm pretty new to really using the CLI - I have no bias towards POSIX compliance... what I'd want out of POSIX compliance is that commands can be composed together - so Nushell out the gate delivers what I assumed was the point of POSIX, with a lot less headache.
As an old fart software developer who has been using sh/ksh/bash/zsh since the dawn of time, if I were in your position I would DEFINITELY ignore them (except where they are explicitly required) and focus on nushell.
Two months on, how are you feeling about nushell? I've played with it a bit. I like a lot, but it's also a fair amount to learn, so I'm wondering if you are happy with it.
A new video about Nushell is coming in a few weeks. TL;DR; I love it and use it for all my scripts/CLIs for a while now. However, I'm not using it as my Shell since I prefer to be "compatible" with the majority. So, a huge yes to scripts, no to Shell.
The Windows equivalent to macOS' "open" is "start". "start ." will open the current directory in Explorer, "start file.txt" will open a file in notepad (or whatever your default text editor happens to be). It's funny that you used this specific example for "Nushell works everywhere", though - nushell has it's own "open" command, which is essentially like "cat", but it will try to convert the file to a table. Enjoyed the video, still not sure if I want to seriously try to use nushell, though :)
That's an example of a type of s command that exists in all OSes, yet the command itself is different in each (open/start/xdgopen). I knew that there is one in windows but wasn't sute ehich one it is. Thanks for the info.
You can `alias read = open; alias open = wslview # or explorer, or start, or xdg-open`, they suggest it in docs, however makes me wonder if it affects .nu scripts then. Also it breaks help menu, it will report that the command is alias instead of showing useful info. While they have escape hatch for system commands ^, there is no equivalent to specify that you want exactly nushell's own command.
Yeah, as others have said, this very much reminds me of PowerShell. I have been one of those odd guys out for a while now saying how powershell is actually an excellent shell, and now I'm going to have to check this one out. Unlike nushell's data pipes, PowerShell pipes full objects in between programs. Overall It is great, but it is highly dependent on the ecosystem of other tools supporting that functionality. I love how nushell lets you detect Data from columns and objects and stuff.
Thanks for always great content! I think Nushell looks amazing! I have a 10+ years Powershell background and have often talked with Linux/bash people who did not get how powerful Powershell is. Passing data or objects is just superior compared to passing text around and Powershell has been able to do that for 10 if not 15 years. So in that way I'd say it is about time something similar arrives on Linux and Mac. I know this is not about Powershell, and that it is not perfect either, but it is super powerful and structured compared to various bash commands, that are often the alternative. If Powershell hadn't come out of MS and was cross-platform from the start, we might not have Nushell now.. I see a huge overlap and the fact that Powershell is not used more on none-Windows platforms than it is. I suspect that has something to do with open-source/Linux vs Microsoft from way back. From back when Linux was considered better and finer by many and everything coming out of MS was just bad per definition. Powershell on Linux is also amazing, very user-friendly, very consistent. I'll definitely give Nushell a try. Very inspirational!
I was using powershell at work for some time and got frustrated how dreadfully slow it was in combination with our Endpoint security software.... running "pwsh -NoProfile -c 'echo hello' " can take up to 4 seconds, i'm really not sure what they are doing there nushell being fast was the initial reason to try it, and now i'm a complete convert (only get tripped up when writing functions sometimes, i feel like powershell's syntax was less whitespace sensitive...)
Thank you for another great video! Definitively interesting, I'm giving it a try right now. I agree that is indeed a new breed of shells, if you need the power of data manipulation it can really be a lifesaver
One way or another, much of what we do in shells is about data manipulation. Every time we pipe one command to another we are sending output of one as input to another. The question is mostly whether that data is text or structured.
Tried it recently, but ran into weird issues - like shell hangs on ctrl+c sometimes, or has terrible lag on completions because those seem to be syncronous and run something heavy on each keystroke. Even basic stuff like loading .env - good luck to find a makeshift script for that, and when you do, it won't handle newlines properly. While the concept of it is nice, it's those little compound frustrations that make me stick with zsh.
I'm not 100% sold to the idea of using Nushell as my daily driver shell. I don't think I need such complex data processing, even in your example - most likely I'd accept downside of no having e.g. files bigger than 1kB... The things changes drastically if we're talking about a scripting language. And here I could imagine writing a tool that manipulates the data in NS. But here another question raises immediately - if the tool is going be a little more complex, wouldn't it be better to write it completely in Python or even Golang and have something which can be maintained not only the author...?
I tend to use Nushell much more for scripts than commands in a Shell. I find it to be better than Bash scripts, yet, unlike Golang, focused on being a scripting language. That being said, if I need to create a "serious" CLI, I would still go with Go, but for anything less complex, I find Nushell to be great.
I think the point that everyone can maintain the script is important. It looks great but I don’t think it’s worth switching if all my coworkers are not using it.
What do you think of Nushell?
Looks great, are you using it as a daily shell?

Surround the lines with brackets; ( and ). There should be no \ at the end of lines.
@@DevOpsToolkit Now I get it. But there are no brackets visible in the video
