Key Simulation

The AutomateLinux daemon provides powerful capabilities to simulate keyboard input events and type strings directly.

Type a String

To type a text string as if it were entered on the keyboard:

d simulateInput --string "Hello World"

Simulate Raw Input Events

To simulate specific input events (like pressing a specific key code):

d simulateInput --type <EV_TYPE> --code <KEY_CODE> --value <VALUE>

• EV_TYPE: Usually 1 for EV_KEY.
• KEY_CODE: The Linux input event code (e.g., 28 for Enter, 30 for A).
• VALUE: 1 for press, 0 for release, 2 for repeat.

Example: Pressing 'A'

# Press 'A' (code 30)
d simulateInput --type 1 --code 30 --value 1
# Release 'A'
d simulateInput --type 1 --code 30 --value 0

Underlying Utilities

The daemon uses InputMapper internally to emit these events to /dev/uinput via the virtual device it creates. This bypasses physical hardware constraints and allows for automation even when physical devices are ignored or grabbed.
