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.

Recently I got really interested in debloating and hardening my operating systems, cause I'm heavily inspired by Unix and "worse is better" philosophy. As I heard bash is heavy and we have much more lightweight and faster alternatives like these mentioned in title. They must be great alternative for scripting and interpreting but is there any reason to use them on my machines as interactive shell? Anyone are using them? Also is it worth to learn them as bash is standard IT industry?

I agree with the idea of debloating and hardening your systems.

It helps to have some context as the approach I would take depends on what kind of system I'm running. I think its also good to identify your priorities to hone your approach.

When I want stability, fast security updates, minimal install size, I usually use Alpine which indeed uses the lighter busybox bin/sh instead of bash.

When it comes to my workstation shell I'm more focused on utility than size. So bash or zsh or fish, or whatever you find the most useful, makes sense to use.
