input-kbd8

Usage

Overview

input-kbd prints the keyboard map of kernel input device devnr on stdout. The keyboard map maps scancodes to keycodes.

If the device supports a keyboard map, it is printed in the following format (from the output for an AT keyboard):

0x0001 = 67 # KEY_F9
0x0002 = 65 # KEY_F7
0x0003 = 63 # KEY_F5
0x0004 = 61 # KEY_F3

If the device does not support a keyboard map, input-kbd just lists the keys and buttons supported by the device, like this (for a mouse):

bits: BTN_LEFT
bits: BTN_RIGHT
bits: BTN_MIDDLE

Options

devnr

The index of the input device to use (0 for /dev/input/event0 and so on).

-f file

Read a keyboard map from a file and reconfigure the device with this map. If the file name is '-' then stdin is used. The map file uses the same format as the output of this command. Blank lines are ignored. A '#' character and anything following it on the same line are ignored as a comment. Scancodes and keycodes are decimal values unless proceeded by "0x" for hexadecimal. To remove a mapping entirely, set it to 0x00 (RESERVED). Key names are also accepted instead of keycodes, like this:

0x0001 = KEY_F9

Be careful setting values from 0 to 9, as they will be parsed as the key symbols, not the decimal numbers. If you want to list a single-digit decimal keycode, specify it as a hexadecimal value to remove any ambiguity.
