A little gem! The Fish Shell https://fishshell.com/
TLDR; Simpler, faster stronger bash (no Kayne West)
A few months ago I needed a shell scripting language that suited my needs, that needed to be:
- Faster than bash
- Less words to type
- Compact functions, loops and variable statements
- Tab autocomplete; and
- Make my life just that little bit easier (RSI).
