将传感器输出提取到已排序的数组中 [英] Extracting Sensors Output into Sorted Array

问题描述

此问题是使用脚本提取Ubuntu Sensors命令的延续

由于问题写得不好，我以新问题的形式改写了问题.

Since the question was poorly written, I'm rewording the question in form of new question.

基本上，我想使用传感器命令和诸如gawk和bash之类的脚本来提取GPU温度信息.

Basically I want to extract GPUs temperatures information using sensors command and scripts like gawk and bash.

传感器输出示例如下:

amdgpu-pci-0c00
Adapter: PCI adapter
fan1:        1972 RPM
temp1:        +50.0°C  (crit =  +0.0°C, hyst =  +0.0°C)

amdgpu-pci-0600
Adapter: PCI adapter
fan1:        1960 RPM
temp1:        +47.0°C  (crit =  +0.0°C, hyst =  +0.0°C)

amdgpu-pci-0200
Adapter: PCI adapter
fan1:        1967 RPM
temp1:        +52.0°C  (crit =  +0.0°C, hyst =  +0.0°C)

pch_skylake-virtual-0
Adapter: Virtual device
temp1:        +33.0°C

amdgpu-pci-0900
Adapter: PCI adapter
fan1:        1893 RPM
temp1:        +51.0°C  (crit =  +0.0°C, hyst =  +0.0°C)

amdgpu-pci-0300
Adapter: PCI adapter
fan1:        1992 RPM
temp1:        +53.0°C  (crit =  +0.0°C, hyst =  +0.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +24.0°C  (high = +80.0°C, crit = +100.0°C)
Core 0:        +23.0°C  (high = +80.0°C, crit = +100.0°C)
Core 1:        +21.0°C  (high = +80.0°C, crit = +100.0°C)

GPU临时信息标记为amdgpu-pci-"BUS_ID"，因此我们不在乎其他标签方案(skylake-virtual或coretemp-isa).需要做的事情是:

The GPU temp information is labeled amdgpu-pci-"BUS_ID", so we don't care about other label scheme (skylake-virtual nor coretemp-isa). Things need to be done are:

1. 提取GPU温度信息，例如amdgpu-pci-0c00 具有50度，并放入一个数组中.
2. 数组索引应从0开始并按顺序升序 BUS ID.

1. Extracting the GPU temperatures info, for example amdgpu-pci-0c00 has 50 degree, and put in into an array.
2. The array index should be started with 0 and ascending in the order of BUS ID.

如果使用上述数据，则以a为名称的数组为:

If using the above data, the array assuming a is the name, would be:

a[0] = 52 ;amdgpu-pci-0200
a[1] = 53 ;amdgpu-pci-0300
a[2] = 47 ;amdgpu-pci-0600
a[3] = 51 ;amdgpu-pci-0900
a[4] = 50 ;amdgpu-pci-0c00

我需要的输出是一个无限循环，该循环不断使用其值更新数组索引:

What I need for the output is an infinite loop that keep updating the array index with its value:

0 => 52
1 => 53
2 => 47
3 => 51
4 => 57

新值应在旧值上打印，因此不会拖尾.更新应具有1秒的延迟，以便操作员可以轻松评估这些值.

The new value should print over the old value so it won't trail. The update should have 1 second delay so the operator can easily evaluate the values.

GAwk可以完成提取和排序，但是我需要将其存储在bash中的数组中，以便可以将其用于其他过程.

The extracting and sorting could be done by GAwk, but I need it to be stored in an array in bash so that I can use it for other process.

推荐答案

重复使用脚本中的部分和Ed Mortons的答案，我认为这可能对您有用:

Reusing parts from your script and Ed Mortons answer I think this might work for you:

#!/bin/bash

while true
do
  while read -r i temp ; do
    echo -en  "GPU $i temp is $temp \r "
    sleep 1
  done < <(
    sensors | gawk '
      !NF {name=""}
      /amdgpu/ {
        name=$1
      }
      /^temp1:/ && name {
        temps[name]=gensub(/^[^0-9]*([0-9]+).*/,"\\1",1,$2);
      }
      END {
        PROCINFO["sorted_in"] = "@ind_str_asc"
        ctr=0;
        for (i in temps) {
          print ctr++,temps[i]
        }
      } '
  )
done

如果出于其他目的需要将值存储到数组中(如问题中所述)，则可以执行以下操作:

if you need to store the values to an array (as stated in the question) for other purposes you can do it like this:

temps=( $( sensors | gawk '...' ) )

在这种情况下，将awk中的打印命令更改为仅打印温度[i].我的方法可以轻松扩展为包括传感器输出中的其他值(例如gpu标签或风扇速度).

In this case change the print command in awk to only print temps[i]. My approach can be easily extended to include other values from the sensors output (like the gpu labels or fan speed).
