Fish terminal is a great terminal. I was initially heisitant to try it but cnce I gave it a go I really liked it.
You should try it as well!
I particularly how it shows a type ahead for commands you have previously written! You can easily press right arrow to autocomplete the command you were writing! This is a big time saver.
Install using the following to ensure you get the lastest version of fish
sudo add-apt-repository ppa:fish-shell/release-3 sudo apt-get update sudo apt-get install fish
Add the fish shell /usr/local/bin/fish to /etc/shells with:
echo /usr/local/bin/fish | sudo tee -a /etc/shells
Setting as default terminal
Change your default shell to fish with:
chsh -s /usr/bin/fish
