How to Install Fish Shell on Ubuntu

Fish is a helpful shell for Linux. It makes using the terminal easier, but it’s not like other shells you might be used to.

1. Install Fish Shell using the default repository

The easiest way to get Fish is by using a simple command:

sudo apt install fish

After it’s installed, you can check which version you have:

fish -v

To start using Fish, just type fish in the terminal.


To stop using Fish and go back to your regular shell, type exit.


2. Get the latest version of Fish Shell

If you want the newest version of Fish, you’ll need to use Fish’s PPA. First, add the PPA to your system:

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

Then, update your system:

sudo apt update

Once that’s done, install Fish with this command:

sudo apt install fish

Now, check the version again:

fish -v
