Install Fish shell and Oh My Fish in Ubuntu 20.04

TODO: write an introduction

Install Fish Shell

To install latest Fish shell on ubuntu, open the terminal and run:

sudo apt-add-repository ppa:fish-shell/release-3
sudo apt update
sudo apt install fish

And That’s all you need to do to install fish shell. But wait, there’s more..

Make Fish shell your default shell

In a terminal run:

chsh -s $(which fish)

to make fish shell default shell for your user.

Install Oh My Fish (recommended)

With fish shell you’d also want to install Oh My Fish, which is just as easy to install:

curl https://raw.githubusercontent.com/oh-my-fish/oh-my-fish/master/bin/install | fish

After installing Oh My Fish you can now install a theme for your fish shell. For example if you want to install agnoster, you can install that by running:

omf install agnoster

Add some configuration (optional)

~/.config/fish/config.fish is the Fish shell’s equivalent of ~/.bashrc. This is how my config.fish looks like:

set -g -x fish_greeting ''

alias la 'ls -A'
alias cd.. 'cd ..'
alias c 'clear'
alias v. 'vim .'
alias nvim. 'nvim .'
alias code. 'code . --disable-gpu && exit'
