Configuring Fish Shell on Ubuntu

README.md

Steps to configure shell fish

0. Install fish and start terminal

brew install fish && fish

1. Install starship theme

curl -sS https://starship.rs/install.sh | sh

2. Add fish to etc shell

echo $(which fish) | sudo tee -a /etc/shells

3. Making fish as default she

chsh -s $(which fish)

If you receive an error like this

chsh: /home/linuxbrew/.linuxbrew/bin/fish is an invalid shell

Try add fish in shells list with command echo $(which fish) | sudo tee -a /etc/shells and then execute the command chsh -s $(which fish) again

4. Add file starship.toml (optional)

It is the file that I like use, you can use another

# ~/.config/starship.toml
# Inserts a blank line between shell prompts
add_newline = false

[username]
show_always = true

[directory]
truncate_to_repo = true
truncation_length = 3

[container]
disabled = true

6. Add to the end of ~/.config/fish/config.fish to init starship when fish start

starship init fish | source
