11/24/2024 Setup fish as default shell on macOS

Install `fish`

On whatever terminal you are, install fish :

brew install fish

Note that, due to a brew --prefix variation, the installation path will vary :

/opt/homebrew/bin/fish on MacOS Silicon
/usr/local/bin/fish on MacOS Intel

which fish

Update `/etc/shells`

sudo sh -c 'echo /opt/homebrew/bin/fish >> /etc/shells'

Restart your terminal.

Make `fish` your default shell with `chsh`

chsh -s /opt/homebrew/bin/fish

Restart your terminal.

Check `$SHELL`

( After restarting your terminal )

echo $SHELL
