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.

Feel like most people still do the scripting in Bash for portability reasons, and then just run Fish as the interactive shell
I use fish, have never once written a fish script. Just write bash scripts and they tend to work fine, otherwise run em in bash
For what it's worth, Debian and most of its derivatives use
dash(a Linux port ofash) instead ofbashfor/bin/sh. It's ~4x faster and uses much less RAM than Bash. Usually the only scripts that use Bash are scripts that aren't POSIX compliant or that use Bash-specific features.
