为什么重定向GAWK的StandardOutput总是在fstat之前添加

问题描述

我有以下代码来读取gawk并将其输出预测到文本文件(而不是使用shell-execute并使用> 进行此操作):

I have following code to read and redict the output of gawk to a textfile (instead of doing this with shell-execute and using >):

var processStartInfo = new ProcessStartInfo
                       {
                         FileName = "gawk.exe",
                         Arguments = $@"-F ""{separator}"" -f ""{scriptFullFileName}"" ""{inputFullFileName}""",
                         UseShellExecute = false,
                         WorkingDirectory = workingDirectory,
                         RedirectStandardOutput = true,
                         CreateNoWindow = true
                       };
using (var process = Process.Start(processStartInfo))
{
  using (var streamReader = process.StandardOutput)
  {
    var result = streamReader.ReadToEnd();
  }
}

随后检查结果，它总是以以下几行开头:

Inspecting result afterwards, it always starts with the following lines:

从外壳执行 gawk.exe 时，这些行不存在.

Whereas executing gawk.exe from the shell, these lines are not present.

我在做什么错-或更妙的是，如何在不进行额外分析的情况下摆脱这两行?

What am I doing wrong - or better, how can I get rid of these 2 lines without additional parsing?

推荐答案

此问题与使用的gawk.exe版本有关，该版本为 3.1.6.2962 .使用 4.1.3 不会发生此问题.

This very issue is connected to the used version of gawk.exe, which was 3.1.6.2962.With 4.1.3 this problem does not occur.
