连接 CSV 文件并跳过第二行

Question

我正在使用 PowerShell 连接社交媒体日志文件，而 Facebook 以其无穷的智慧在其标题行中添加了第二行。

我目前使用这个：

Get-ChildItem -Filter *.csv | Select-Object -ExpandProperty FullName | Import-Csv | Export-Csv $FileOut -NoTypeInformation -Append

连接 Twitter 日志，效果很好。有没有一种“简单”的方法可以在连接期间简单地跳过所有文件中的第二行？我知道我可以在从结果文件中删除第二行（因为它是静态的）之后做一些数据工作，但我宁愿看看我是否可以从一开始就摆脱它。

如果有人好奇，我可以分享前两行，但它特别长而且很烦人=D

ETA：理想情况下，我要么需要弄清楚 a）如何获取该连接行并让它知道标题有两行长，然后我可以从结果文件中删除第二行 要么 b）如何让连接过程跳过每个文件中的第二行而无需大量工作。

这是文件的前两行（所有这些都是真正相关的，因为第二行是我想跳过的那一行）：

Answer 1

-Skip/-SkipIndex 应该可以正常工作，但是 Facebook 以其无限的智慧决定让第一行中的项目不是唯一的，所以我将不得不不走捷径只是删除第二行，而不是删除前两行并添加我自己的标题，这样我就可以在完成后处理数据。

Answer 2

对于5.1，您可以从arraylist 中删除特定索引。该方法不输出到管道，因此需要循环：

foreach ($file in (Get-ChildItem -Filter *.csv).FullName) {
  $csv = [System.Collections.ArrayList](Import-Csv $file)
  $csv.RemoveAt(1)
  $csv | Export-Csv $FileOut -NoTypeInformation -Append
}
