Examples (TL;DR)


alacritty [Subcommands] [Flags] [Options]


Alacritty is a modern terminal emulator that comes with sensible defaults, but allows for extensive configuration. By integrating with other applications, rather than reimplementing their functionality, it manages to provide a flexible set of features with high performance.

   2. $XDG_CONFIG_HOME/alacritty.yml
   3. $HOME/.config/alacritty/alacritty.yml
   4. $HOME/.alacritty.yml

On Windows, the configuration file is located at %APPDATA%\alacritty\alacritty.yml.
