Question

我是一名JavaScript / Java程序员，编写bash脚本时遇到困难。以下是我要处理的输出：

private int price;
public int Price
{
  get { return price/100m; }
  set { price = value; }
}

我希望获得karl@karl-laptop:~/.scripts/startup$ xinput list ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ Logitech USB Receiver id=10 [slave pointer (2)] ⎜ ↳ Logitech USB Receiver id=11 [slave pointer (2)] ⎜ ↳ PS/2 Logitech Wheel Mouse id=15 [slave pointer (2)] ⎜ ↳ SteelSeries Sensei Raw Gaming Mouse id=16 [slave pointer (2)] ⎜ ↳ SteelSeries Sensei Raw Gaming Mouse id=17 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Video Bus id=8 [slave keyboard (3)] ↳ Sleep Button id=9 [slave keyboard (3)] ↳ USB2.0 UVC HD Webcam id=12 [slave keyboard (3)] ↳ Asus WMI hotkeys id=13 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=14 [slave keyboard (3)] ↳ SteelSeries Sensei Raw Gaming Mouse id=18 [slave keyboard (3)] Virtual core pointer的身份证明。这意味着我希望最终得到id：

SteelSeries Sensei Raw Gaming Mouse

最好在他们自己的变量中，因为我将以不同的方式编辑两者的设置。我目前有以下脚本，但它没有做任何事情：

16
17

我尝试在这个问题中使用以下脚本，但它没有起作用，它只是回应所有id：How to make a program that finds id's of xinput devices and sets xinput some settings

我确实对其进行了修改，以便收集与#!/bin/bash ids=$(xinput list | awk 'SteelSeries Sensei Raw Gaming Mouse') echo $ids[0] echo $ids[1] unset $ids匹配的所有ID：

SteelSeries Sensei Raw Gaming Mouse

输出：

ids=$(xinput --list | awk -v search='SteelSeries Sensei Raw Gaming Mouse' \
    '$0 ~ search {match($0, /id=[0-9]+/);\
                  if (RSTART) \
                    print substr($0, RSTART+3, RLENGTH-3)\
                 }'\
     )

for i in $ids
do
    echo $i
done

echo $ids[0]
echo $ids[1]

然而，它还收集了我想要的16 17 18 // <-- wrong! should not be there 16 17 18[0] // <-- I only wanted the number '16' here 16 17 18[1] // <-- I only wanted the number '17' here（你可以看到18号）

Answer 1

以下是提取您感兴趣的两个ID的快速解决方案：

xinput --list | awk '/SteelSeries Sensei .*pointer/ {print $8}' | sed 's/id=\(.*\)/\1/'

获取xinput列表指针的id
