On the other hand, I see quite a few projects challenging The Way Things Are Done (Rust, NeoVim, Fish, OilShell, etc) to which there is a lot of kicking and screaming that things are fine. No need to change.
What you often see are half-baked, trivial re-implementations of some parts of existing utilities and then the proclamation "Rust is here and it's so much better!".
A program that amounts to some undergrad's semester project isn't going to be taken seriously - and they often are not. The existing utilities are decades old, are very good at what they do, and rarely are the cause of the supposed bugs we're trying to avoid.
Shell replacements, such as OilShell, can gain traction on their own, because a shell is mostly system agnostic. The struggle here is reaching critical mass of users, while also supporting all of the millions of existing shell scripts out there in the wild.
No one is going to make your new wiz-bang shell the system default on a popular distro without it being completely compatible with existing shell scripts, documentation, examples, etc. It's just a non-starter...
False. zsh is not POSIX nor fully compatible with bash, while being default login shell in popular distros like Kali and Deepin (and macOS).
Not sure if Garuda Linux passes the "popular" threshold for you but their default is fish.
Shell scripts typically lead with a shebang, making your login shell inconsequential as long as you have the target shell available.
Kali is a purpose-built distro that is not a daily driver for nearly anyone.
Deepin is a Chinese distro, and while it may be popular to some, it is not a popular distro at large.
My point remains standing.
> Shell scripts typically lead with a shebang, making your login shell inconsequential as long as you have the target shell available.
Of course - but having multiple shells installed is not common. What's the point of using another shell if all of your scripts have to use bash anyway? You are still effectively using Bash, and have unintentionally exposed the problem with all non-POSIX compliant shells - they don't allow people to get work done.
Excuse me, how is that in any way relevant here? Fuck off with that.
> but having multiple shells installed is not common
False again. Run 'chsh' and tell me how many options you see.
What on earth are you talking about?
Deepin Technology is a wholly owned subsidiary of UnionTech, a Chinese company based in Wuhan China.
It is a Linux Distro developed in China for a domestic audience, ie. used predominantly in China by Chinese citizens. It is a Chinese Linux Distro...
It may be popular in China, but it is not globally popular. Very few people would willingly choose to run an operating system developed in China for domestic consumption, for very obvious reasons.
Pretend to be offended by something else...
> Run 'chsh' and tell me how many options you see.
Ya... only bash available on my system... a default installation of Rocky Linux.
Usually people try to ensure they're correct before saying someone is wrong.
RockyLinux as you know is a RHEL clone. RHEL is a very conservative distro, their original market was refugees from Solaris and other commercial UNIX distros. And I say that as a diehard fan of Redhat/Fedora minimal installation as both a server and development platform.
Other less commercial distros (Debian and deriviatives, Arch, Gentoo etc) tend to offer more shell options out of the box, as do most of the BSD's. And other options are not hard to install from the Redhat/Fedora repos as you would know.
rust itself is an example. The concepts it's based on predate it by decades. When it comes to safety it's not as good as other languages and yet...
But I've also written a whole lot of software which really couldn't care less about the OS. It needs some way to list directories, some way to read and write files, maybe some way to communicate over the network, but everything interesting happens in code that's not related to interacting with the OS. In those cases, I love that I can just write against one API and know that, if it doesn't already just work on all posixy systems, it's at least going to be easy to port.
