Like Shooting Fish(shell) In A Barrel
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).
So I found this gem, straight from the 90’s (not really); The Fish Shell
Lets crack on
Fish also have some really cool themes! If your anything like me and spend a lot of your time terminalingitup… Its better to look at something nice all day.

Don't let your scripts be so Dorring…
I switch from bash to fish a few months ago and I have been trying to convince my friends (do I have any LOL) to try it out and give it a whirl. For me, it works amazingly so you should give it a go, bash could be your ex and fish could be your new lover!
A few examples, to get you interested!
Less code to type! Below are some examples of how it can make you code that little bit faster.
