Someone will always have a slicker Git workflow than you. For example,Auto-squashing Git Commits for clever rebasing.
I’ve been using the
fish shell for about five months and it is pretty great. A shell with human affordances! It has very good guesses about what I want to do (completions) and what I want it to remember (history). You can configure it with a web interface or regular-old dotfiles. It doesn’t do anything bizarrely different from your typical Unix-style shell, namely
bash, so there’s not much new to learn and when I SSH to a server, I don’t wonder what kind of weird contraption I’m interacting with. I haven’t bothered to learn its scripting language because I’ve decided no one should learn those anymore and they should use Ruby, Python, Go, etc. for that kind of thing.
