xdotool lets you simulate keyboard input and mouse activity, move and resize windows, etc. It does this using X11’s XTEST extension and other Xlib functions.

⚠ Note: If you are using Wayland, please be aware this software will not work correctly. ⚠

With xdotool, you can search for windows and move, resize, hide, and modify window properties like the title. If your window manager supports it, you can use xdotool to switch desktops, move windows between desktops, and change the number of desktops.

Also in this repository is libxdo, a C library for doing the same.

You may view the user documentation in xdotool.pod

You may find xdotool in your distribution packaging:

• Debian and Ubuntu: apt-get install xdotool
• Fedora: dnf install xdotool
• FreeBSD: pkg install xdotool
• OSX: brew install xdotool
• OpenSUSE: zypper install xdotool

From your terminal, run:

xdotool type "Hello world"

xdotool key ctrl+l

The above will simulate the keystrokes as if you pressed the control key, then the "L" key, and then released both. This is useful for simulating hotkeys.

xdotool selectwindow windowclose

This will close the first window you click on.

xdotool search "Mozilla Firefox" windowactivate --sync key --clearmodifiers ctrl+l

xdotool search --onlyvisible --classname "gnome-terminal" windowsize %@ 500
