I installed view brew cask install kitty. Opened kitty.app. Everything seems find. I started to dig into the docs more and saw several places talking about a CLI tool kitty. I tried to add Fish shell completion using this but get this error.

I'm on the latest macOS 10.14.1 & kitty 0.13.1.
What am I doing wrong?
Sorry I dont support the brew kitty, I have no idea what it does. If you install kitty from the official dmg, it will automatically add a directory to PATH from which kitty is available.
@jsatk,
The Homebrew formula installs the kitty application – for me, at least – at /Applications/kitty.app; the kitty executable can then be found at /Applications/kitty.app/Contents/MacOS/kitty.
To include this file in your PATH, you could add it to your PATH variable in your shell startup file, or you could create a symlink in, for example, /usr/local/bin: ln -s /Applications/kitty.app/Contents/MacOS/kitty /usr/local/bin/kitty.
