dotool

dotool reads commands from stdin and simulates keyboard and pointer events. It works everywhere on Linux, including in X11, Wayland and TTYs.

Install From Source

With go and libxkbcommon-dev installed, run:

sudo ./install.sh

Permission

dotool requires permission to /dev/uinput to create the virtual input devices, and a udev rule grants this to users in group input.

You could try:

echo type hello | dotool

and if need be, you can run:

sudo groupadd -f input
sudo usermod -a -G input $USER

and re-login and trigger the udev rule or just reboot.

Usage

See dotool --help, but this greets the world:

echo 'type Sup, Lads!' | dotool

and this screams for three seconds:

{ echo keydown A; sleep 3; echo key H shift+1; } | dotool

There is an initial delay registering the virtual devices, but you can keep writing commands to the same instance or use the daemon and client, dotoold and dotoolc.

dotoold &
echo type super | dotoolc
echo type speedy | dotoolc

Keyboard Layouts

dotool will produce gobbledygook if your environment has assigned it a different keyboard layout than it's simulating keycodes for. You can match them up with the environment variables DOTOOL_XKB_LAYOUT and DOTOOL_XKB_VARIANT.

echo type azerty | DOTOOL_XKB_LAYOUT=fr dotool
