Install ‘Oh My Fish’ with the theme ‘Bob The Fish’

  1. Install Oh My Fish curl https://raw.githubusercontent.com/oh-my-fish/oh-my-fish/master/bin/install | fish

  2. Install Theme: Bob the Fish omf install bobthefish

Install powerline fonts

  1. Install Powerline fonts (Ubuntu/Debian/Mint Linux) sudo apt-get update sudo apt-get install fonts-powerline

Fix fonts using WSL or Remote

The powerline and theme of oh my fish / bob the fish will not be shown correctly. Instead fancy symbols are shown.

Make sure that your console / terminal application like Windows Terminal or Visual Studio Code are using a font with is patched with powerline symbols.

Under windows, a good suggestion is to use MS font Cascadia in its variant Cascadia (Code|Mono) PL. You can find it at Cascadia Code on Github.
