ydotool cmd –help
ydotool lets you programmatically (or manually) simulate keyboard input and mouse activity, etc. It does this by writing directly to /dev/uinput so it generally needs to run as root.
It’s possible to chain multiple commands together, separated by a comma between two spaces.
Currently implemented command(s):
type Type a string key Press keys mousemove Move mouse pointer to absolute position click Click on mouse buttons recorder Record/replay input events sleep sleep for a while
key [–up] [–down] [–next-delay
Type a given keystroke. Examples being "alt+r", "ctrl+J", "ctrl+alt+n", "backspace". Options: *--up* Only keyup *--down* Only keydown *--delay* _<ms>_ Delay before starting to output keystrokes. Default 100ms. *--key-delay* _<ms>_ Delay time between keystrokes. Default 12ms. *--repeat* _<times>_ Times to repeat the key sequence. *--repeat-delay* _<ms>_ Delay time between repetitions. Default 0ms. Generally, any valid name from _/usr/include/linux/input-event-codes.h_ will work. Multiple keys are separated by '+'. Each key sequence can be any number of modifiers and keys, separated by plus (+) For example: alt+r Alt+F4 CTRL+alt+f3 aLT+1+2+3 ctrl+Backspace Since we are emulating keyboard input, combinations like Shift+# is invalid because typing a `#' involves pressing Shift and 3. Example: Switch to tty1: ydotool key ctrl+alt+f1 Example: Close a window in graphical environment: ydotool key Alt+F4
Types text as if you had typed it on the keyboard. Options: *--next-delay* _<ms>_ Delay before starting typing. Default 100ms. *--key-delay* _<ms>_ Delay time between keystrokes. Default 12ms. *--texts* _arg_ Texts to type *--file* _<filepath>_ Specify a file, the contents of which will be typed as if passed as an argument. The filepath may also be '-' to read from stdin. Example: to type 'Hello world!' you would do: ydotool type 'Hello world!'
Options: *--absolute* Use absolute position Example: to move the cursor to absolute coordinates (100,100): ydotool mousemove --absolute 100 100
Options: *--next-delay* _<ms>_ Delay before click. Default 100ms. *--up* Only mouseup *--down* Only mousedown *--buttons* _<arg>_ Buttons to press (left, right, middle) Example: Mouse middle click: ydotool click middle
Options: *--record* _<devices>_ Devices to record from. Default is all, including non-keyboard devices. *--replay* _<input files>_ The record file can't be replayed on an architecture with different endianness. *--display* Display *--duration* _<ms>_ Record duration. Otherwise use SIGINT to stop recording. *--devices* _<path>_ Devices, separated by comma, to record from. Default is all devices (default: "") *--file* _<path>_ File to record to / replay from
When ydotool(1) runs and creates a virtual input device, it will take some time for your graphical environment (eg X11/Wayland) to recognize and enable the virtual input device. (Usually done by udev)
If the delay is too short, the virtual input device may not be recognized & enabled by the graphical environment in time.
In order to solve this problem, there is a persistent background service, ydotoold(1), to hold a persistent virtual device, and accept input from ydotool(1). When ydotoold(1) is unavailable, ydotool(1) will work without it.
