Syntax

Ducky Script syntax is simple. Each command resides on a new line and may have options follow. Commands are written in ALL CAPS, because ducks are loud and like to quack with pride. Most commands invoke keystrokes, key-combos or strings of text, while some offer delays or pauses. Below is a list of commands and their function, followed by some example usage.

Note: In the tables below //n// represents a number and //Char// represents characters A-Z, a-z.

REM

Similar to the REM command in Basic and other languages, lines beginning with REM will not be processed. REM is a comment.

Command
REM

REM The next three lines execute a command prompt in Windows

GUI r

STRING cmd

ENTER

DEFAULT_DELAY or DEFAULTDELAY

DEFAULT_DELAY or DEFAULTDELAY is used to define how long (milliseconds) to wait between each subsequent command. DEFAULT_DELAY must be issued at the beginning of the ducky script and is optional. Not specifying the DEFAULT_DELAY will result in faster execution of ducky scripts. This command is mostly useful when debugging.

CommandParameters
DEFAULT_DELAY0..->
DEFAULTDELAY0..->

DEFAULT_DELAY 100

REM delays 100ms between each subsequent command sequence

DELAY

DELAY creates a momentary pause in the ducky script. It is quite handy for creating a moment of pause between sequential commands that may take the target computer some time to process. DELAY time is specified in milliseconds from 1 to 10000. Multiple DELAY commands can be used to create longer delays.

CommandParameters
DELAY0..->

DELAY 500

REM will wait 500ms before continuing to the next command.

STRING

STRING processes the text following taking special care to auto-shift. STRING can accept a single or multiple characters.

CommandParameters
