input-kbd - print or modify keyboard maps for input devices
Contents
Description
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

input-kbd - print or modify keyboard maps for input devices
Options
devnr The index of the input device to use (0 for /dev/input/event0 and so on).
-ffile
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.
