What’s your favourite to use? Mine is Fish due to its ease of use and user friendly approach.
Bash is the pepperoni of shell tools being reliable in every field no matter what but I’ve moved to Fish as I wanted to try something different.
So what’s your shell of choice?
OpenBSD’s default public domain kornshell fork on OpenBSD, oksh (portable OpenBSD ksh clone) on Linux/MacOS/Other Unix. It has far fewer extensions than something like Bash (which I consider a positive) while being much faster (tested with hyperfine), and the extensions it does have are all useful (arrays, coprocesses, select, .* not expanding to . or .., pattern blocks, suspending of the whole shell).
