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 like fish abbreviations. They are like aliases but expand when you press space or enter. That way you can edit it, and also still see the full command so you are less likely to forget it when you don't have your aliases. Of course I have some scripts as well.
I use ZSH with plugins but back when I switched away from bash, I also looked at fish. I didn't use it back then because people say it doesn't follow the POSIX standard but is that really an issue? It probably only extends it instead of taking things away, right?
Unless you have a particular reason for sticking to POSIX, who cares? I'll take the user experience improvement without worry.
The thing is that, if you are not sticking to POSIX, you might as well use more widely available alternative scripting languages like perl or python, which are often included in most workspaces by default, so I'd say it's more useful to get experienced in those than to get experienced in fish.
