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. See the 'Wayland' section below for more detail.

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
• macOS: brew install xdotool or sudo port 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
500

Wayland is a very different graphics system than X11 (which you might know as Xorg or X). Wayland has some X11 compatibility, but for the purposes of xdotool, many things do not work correctly. Typing, window searching, and many other functions of xdotool do not work, and it is unclear if they could ever work.

Some other tools that might help you if you use Wayland are:

• ydotool - a tool for sending mouse and keyboard events using Linux's uinput sytem
• dotool - a tool for sending mouse and keyboard events using Linux's uinput sytem

Prerequisites:

• X11 libraries: xlib, xtst, xi, xkbcommon, xinerama

How to compile and install:

• Compile: make
• Install: make install
• Remove: make uninstall

You may have to set 'PREFIX' to the location you want to install to. The default PREFIX is /usr/local

For packagers, there's also support for DESTDIR for staged install.

Also, see the manpage, which you can generate by running:

  make showman

Note: the manpage will be installed during 'make install'
