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.

For a long time I used a super customized zsh setup. It was, unfortunately, crazy slow and regularly broke on updates. It had precisely all the features and behavior I wanted though. Like you say, zsh is very customizable.
Then I switched to tiling window managers and with that to the alacritty terminal. This made me value start up times and performance, as I was constantly opening and closing terminals. So I spent a ridiculous amount of time optimizing my zsh config to be as fast as possible. This is also what I used for a long time before correcting my ways.
When that device, my work laptop, failed, I had to set up my desktop for work. This involved setting up zsh, which I quickly realized was a lot of work. So, on a whim, I installed fish.
Oh my god. Not only did fish have nearly all the features I wanted out of the box, but it was easy to add plugins (customizations) in a performant way. Fish even had default behavior I didn't know I needed. And most importantly: it was crazy fast!
Since then I have never left fish. It is so much better than anything I had imagined. At this point I use way more default features as well, so I pretty much only add the tide prompt and zoxide. I also have a functions and abbreviations folder which is essentially my zsh alias collection.
The crazy part is really how much faster it is though. I really, really love it. And now they're rewriting it in Rust as well!
