将具有相同标题的多个CSV文件合并到不同的组文件中

Question

嗨，我正在寻找一个最快的解决方案来处理csv文件的负载。

情况：我在一个文件夹中有多个csv文件，它们的标题不同

我已经对它们进行了预处理，以删除顶部的垃圾行，因此所有这些都有一个标准标头。

我想将一组CSV文件与完全相同的侦听器合并到一个新文件夹中

Single Folder:
    Tree 
    ├── 161598827330618_data_aa.csv 
    ├── ..............  
    ├── ............... 
    ├── ................ 
    ├── 161598852706227_data_bh.csv 
Note: Filenames are Random with no pattern*

首选解决方案：Bash脚本和Linux命令尝试过的解决方案：

#!/bin/bash
awk '
  FNR==1{
    if (!($0 in h)||file!=h[$0]){close(file)}
    if (!($0 in h)){file=h[$0]=i++}
    else{file=h[$0];next}
  }
  {print >> (file)}
' ./*.csv

上述方法有效，但我不确定它是否能处理1000个文件进行处理和分类。我需要一个小组。要在其他文件夹中创建的csv格式。

最短的完成时间很重要https://stackoverflow.com/a/51921621/3088275

寻找带有Awk或Sed的Op代码或bash脚本的Linux命令，这永远是实现所需输出的最快速度

Answer 1

您可以使用以下AWK脚本。我用所有的样本文件进行了测试。

!NF { next }
NR % 3 == 1 { filename = substr($0, 5, length($0)-8) }
NR % 3 == 2 { headers[$0] = headers[$0] (headers[$0] == "" ? "" : ",") filename }

END {
  i=1
  for (header in headers) {\
    printf("Group %02d: %s\n", i, headers[header])
    split(headers[header], a, ",")
    for (idx in a) {
      getline x < a[idx]
      printf "" > sprintf("group%02d.txt", i)
      while (getline x < a[idx] > 0)
        print x >> (sprintf("group%02d.txt", i))
    }
    i++
  }
}
