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 am really struggling with this, I heard about nu shell some time ago, but the fact that you had to learn some form of new language made me reluctant to actually try it. As a fisher user I want to have sane usable defaults, without having to learn just another programming language for a "tool".
What am I missing?
It kinda fills a niche.
I use fish for simple command pipelines as well. But traditional shells are not as good when I need to do anything "structured", because they treats almost any value as a string and don't have anonymous functions. The first problem means that you have to parse a string again and again to do anything useful, the second means that when both pipe and
xargsfails you are doomed.Nu solves both of the big problems that matters when you want to do rather complex but ad-hoc processing of data. And with a rather principled design, nu is very easy to learn (fish is already way better than something POSIX like bash though).
Personally another important reason is that I have a Windows machine at work and nushell is much easier than pwsh.
Btw fish is also going to be a "tool in rust" soon :)
