The fish shell is amazing
I’ve been lurking the fish shell for a couple of years now (and the nushell but it is another story for another time). Not so long ago, I decided to try it, and it’s simply… amazing. If I had to state one feature that makes me like to use it, it’ll be the autocompletion, hands down. It’s the first time I just take a…
