alacritty1

A fast, cross-platform, opengl terminal emulator.

Usage

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.

Flags

-h, --help

Prints help information.

--hold

Remain open after child process exits.

--daemon

Do not spawn an initial window.

--print-events

Print all events to STDOUT.

Options

--class <GENERAL> | <GENERAL>,<INSTANCE>

When only the general class is passed, instance will be set to the same value.

On Wayland the general class sets the app_id, while the instance class is ignored.

-e, --command <COMMAND>...

Command and args to execute (must be last argument).

--config-file <CONFIG_FILE>

Alacritty doesn't create the config file for you, but it looks for one in the following locations on UNIX systems:

1.

$XDG_CONFIG_HOME/alacritty/alacritty.toml

2.

$XDG_CONFIG_HOME/alacritty.toml

3.

$HOME/.config/alacritty/alacritty.toml

4.

$HOME/.alacritty.toml

5.

/etc/alacritty/alacritty.toml

On Windows, the config file will be looked for in:

1.

%APPDATA%\alacritty\alacritty.toml

X11 window ID to embed Alacritty within (decimal or hexadecimal with 0x prefix).

-o, --option <OPTION>...
