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?
Yeah, I mentioned fish, or zsh, only because day to day shell and scripting shell can be different.
If you want to script, bash is the way to go. For day to day, any personal preference is fine.
