@lordalveric fish as in the shell? Havent used it in a bit, if it were compatible with bash I probably would have kept using it. It was nice.
Have you tried zsh + oh-my-zsh. Gives you many of the same features (in fact more) and is fairly compatible with bash.
@freemo I spent a couple of hours converting some of my bash scripts into fish. It's not hard to do at all, and, like I said, the syntax is much cleaner.
