How To Setup Fish Shell

I’ve always been a big fan of pimping out my console. Every time I see one of my coworkers’ monochromatic green shell, I die a little inside.

For a while I was a big fan of Noah Frederick’s peppermint theme and I loved it, but then I discovered Fish shell. Fish shell is sweet, and it does a lot of nice things for you like colors, a fancy prompt, and nifty predictions.

I’ve been using fish for a while now and I don’t see myself going back to bash anytime soon.


Fish shell can be a little daunting to install. I opted to install it from the source – if you’re comfortable with the terminal then do it this way. There’s also a package installer that you can use.

To use fish, simple use the fish command.

> fish

Once you’re down with fish, make it your default shell:

chsh -s /usr/local/bin/fish

Or revert back to bash:

chsh -s /bin/bash

There’s a little gotcha, in order for the chsh command to work you have to have fish in your /etc/shells. You can read the full details cutesy of Nicholas Riley via StackOverflow. This is what mine looks like (note the addition of /usr/local/bin/fish):
