查找报告丢弃错误的所有ASIC

Question

我已经从文件中提取了特定字段(AsicErr)的最高计数，并对其进行了过滤，如下所示：

grep AsicErr file.txt | sort -t: -k2nr | head
EGQ0 AsicErr             :         3464363
EGQ0 AsicErr             :         12312
EGQ0 AsicErr             :         120

基于此，我想进一步过滤此文件，以提取旁边有箭头的行，如下所示：

所需输出：

 RP/0/RP0/CPU0:abc#show controllers fia statistics instance 0 location 0/0/CPU0  
  FIA Statistics Rack: 0, Slot: 0, Asic instance: 0  
  EGQ0 AsicErr                         :         3464363   
  RP/0/RP0/CPU0:abc#show controllers fia statistics instance 3 location 0/0/CPU0   
  FIA Statistics Rack: 0, Slot: 0, Asic instance: 3   
  EGQ0 AsicErr                         :         12312   
 RP/0/RP0/CPU0:abe#show controllers fia statistics instance 1 location 0/0/CPU0   
 FIA Statistics Rack: 0, Slot: 0, Asic instance: 1    
 EGQ0 AsicErr                         :         20   

这可能涉及到搜索错误的数值，然后反向搜索以获得FIA Statistics行，然后反向搜索show命令以捕获面临该问题的设备的主机名。

如果我能得到一些关于如何实现这一点的指导，我将不胜感激。

谢谢。

下面是一个标准的Linux awk脚本：

awk '/AsicDropErr/{print $4}' file1 file2 |sort |head

您可以在awk命令中放入任意多的文件。
