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?
Dash’s more significant feature is its speed. It’s not meant to be used in place of bash at all, its meant to be symlinked in place of sh to give you a faster and smaller shell with a simpler and more auditable codebase.
