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.

Using dash or ksh as default shell (lemmy.world)

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?

Ignoring the interactive features (or lack thereof) in dash/ksh, removing bash is not really something that's possible on most distros (excluding Alpine and possibly Debian) since it's used in scripts everywhere. And if you need to have bash installed anyways, why opt for the less pleasant shell in daily usage?

I don't want to remove bash as my operating system is using it as hard dependency, I was considering using different one. I agree with you at point - installing another shell if all what I need is bash makes my system more bloated.
