主要是对Linux输入子系统的一些简单操作 比如lsinput是看有多少输入设备 比如input-events是看输入设备的键值 用来调试输入子系统很好

.SH NAME
input-kbd \- print or modify keyboard maps for input devices

.SH SYNOPSIS
\fBinput\-kbd\fR \fInum\fR
.HP 10
\fBinput\-kbd \fR [\fB\-f\fR\ \fIfile\fR] \fIdevnr\fR

.SH DESCRIPTION

.PP
\fBinput\-kbd\fR prints the keyboard map of kernel input device
\fIdevnr\fR on stdout.
The keyboard map maps scancodes to keycodes.

.PP
If the device supports a keyboard map, 
it is printed in the following format
(from the output for an AT keyboard): 
.IP
        0x0001 =  67  # KEY_F9
        0x0002 =  65  # KEY_F7
        0x0003 =  63  # KEY_F5
        0x0004 =  61  # KEY_F3
 

.PP
If the device does not support a keyboard map, 
\fBinput\-kbd\fR just lists the keys and buttons supported by the device,
like this (for a mouse):
.IP
        bits: BTN_LEFT
        bits: BTN_RIGHT
        bits: BTN_MIDDLE
 

.SH OPTIONS

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

.TP
\fB\-f\fR \fIfile\fR
Read a keyboard map from a file and reconfigure the device with this map.
The map file uses the same format as the output of this command.
Key names are also accepted instead of keycodes, like this: 
.IP
	0x0001 = KEY_F9
