fish is a very nice shell with autocompletion out of the box. I find it extremely useful. This explains how you can install it on OS X using homebrew and make it even better by using a popwerline style prompt.

Install fish shell

Let’s install it using brew

brew install fish

Add /usr/local/bin/fish to /etc/shells if it is not alredy there:

cat /etc/shells|grep /usr/local/bin/fish ||sudo sh -c 'echo "/usr/local/bin/fish" >> /etc/shells'

make fish your default shell

chsh -s /usr/local/bin/fish

Make the terminal even nicer by customizing the prompt

fish shell is already awesome, but we can make it even better by using a powerline style prompt which displays git branches, the exit status of the last command, the current time and much more.

To install it we are going to use Oh My Fish:

Oh My Fish provides core infrastructure to allow you to install packages which extend or modify the look of your shell. It’s fast, extensible and easy to use.

Install oh-my-fish

curl -L | fish

Now we can use oh my fish to install bobthefish, which is a Powerline-style, Git aware fish theme.

omf install bobthefish

Let’s make it even more awesome by installing nerd-fonts

brew tap caskroom/fonts
brew cask install font-hack-nerd-font

After that you should change the font of your terminal to Knack Nerd Font and enable them in bobthefish

set -g theme_nerd_fonts yes
