从命令行检查锁定键状态

Question

我想从命令行检查锁定键（即 Caps Lock、Num Lock、Scroll Lock 等）状态（开/关）。如何通过终端命令检查状态？

Answer 1

只需运行：

xset q

来自man xset：

q       The q option gives you information on the current settings.

在输出的顶部，您将找到您的信息，如下所示：

Keyboard Control:
  auto repeat:  on    key click percent:  0    LED mask:  00000003
  XKB indicators:
    00: Caps Lock:   on     01: Num Lock:    on     02: Scroll Lock: off
    03: Compose:     off    04: Kana:        off    05: Sleep:       off
    06: Suspend:     off    07: Mute:        off    08: Misc:        off
    09: Mail:        off    10: Charging:    off    11: Shift Lock:  off
    12: Group 2:     off    13: Mouse Keys:  off

您可以使用以下grep方法获得特定结果：

$ xset -q | grep Caps
    00: Caps Lock:   off    01: Num Lock:    on     02: Scroll Lock: off
