Setting up Fish on the Mac

Fish shell is my shell of choice and having it setup as default on the Mac requires some extra steps.

When homebrew is installed, run brew install fish.

After that, edit /etc/shells and add fish to it:

# sudo edit /etc/shells

Add the bottom of the file add:

/opt/homebrew/bin/fish

Then set the shell as default with:

chsh -s /opt/homebrew/bin/fish

It does require logging again to be activated.

env SOME_VAR=1 command
