So I’ve been using Linux now for a while, and am looking to migrate my dev environment to vim and spend more time in the command line. I’m fairly comfortable with bash but by no means an expert. I’ve used zsh with some minor customization but just recently learned about fish. I’d love to hear people’s opinions.
Are you in a tech support role at work? If so are you supporting Linux boxes, either servers or desktops? If yes then stick with BASH and learn VI - not because it is better, but because it comes with almost every distro (a small number install nano instead). If not, try out all the new stuff and see what suits you.
