Linux虚拟机开启键盘灯

在/bin目录下新建led这个文件

status=/tmp/keyboard_led_status
if [[ ${1} == "on" ]] || [[ ! -e ${status} ]]; then
    xset led named 'Scroll Lock' && echo "on" > ${status}
else
    xset -led named 'Scroll Lock' && rm -f ${status}
fi

赋予该文件可执行权限

chmod 777 /bin/led

然后在终端里执行即可开启键盘灯

/bin/led

即可成功开启键盘灯
