有一个Win32端口的Unix tee命令，就是这样做的。见http://unxutils.sourceforge.net/或http://getgnuwin32.sourceforge.net/

这是实时工作，但也是一种丑陋和性能缓慢。也没有经过很好的测试:

@echo off
cls
SET MYCOMMAND=dir /B
ECHO File called 'test.bat' > out.txt
for /f "usebackq delims=" %%I in (`%MYCOMMAND%`) do (
  ECHO %%I
  ECHO %%I >> out.txt
) 
pause

一个简单的c#控制台应用程序就可以做到这一点:

using System;
using System.Collections.Generic;
using System.IO;

namespace CopyToFiles
{
    class Program
    {
        static void Main(string[] args)
        {
            var buffer = new char[100];
            var outputs = new List<TextWriter>();

            foreach (var file in args)
                outputs.Add(new StreamWriter(file));

            outputs.Add(Console.Out);

            int bytesRead;
            do
            {
                bytesRead = Console.In.ReadBlock(buffer, 0, buffer.Length);
                outputs.ForEach(o => o.Write(buffer, 0, bytesRead));
            } while (bytesRead == buffer.Length);

            outputs.ForEach(o => o.Close());
        }
    }
}

要使用该命令，只需将source命令导入程序，并提供要将输出复制到的任何文件的路径。例如:

dir | CopyToFiles files1.txt files2.txt 

将显示dir的结果，并将结果存储在files1.txt和files2.txt中。

请注意，上面的错误处理方式并没有太多(任何东西!)，实际上可能并不需要支持多个文件。

我也在寻找同样的解决方案，经过一些尝试，我成功地在命令提示符中实现了这一点。以下是我的解决方案:

@Echo off
for /f "Delims=" %%a IN (xyz.bat) do (
%%a > _ && type _ && type _ >> log.txt
)
@Echo on

它甚至还可以捕获任何PAUSE命令。

I agree with Brian Rasmussen, the unxutils port is the easiest way to do this. In the Batch Files section of his Scripting Pages Rob van der Woude provides a wealth of information on the use MS-DOS and CMD commands. I thought he might have a native solution to your problem and after digging around there I found TEE.BAT, which appears to be just that, an MS-DOS batch language implementation of tee. It is a pretty complex-looking batch file and my inclination would still be to use the unxutils port.

另一种选择是在程序中tee stdout到stderr:

在java中:

System.setOut(new PrintStream(new TeeOutputStream(System.out, System.err)));

然后，在你的dos批处理文件:java程序> log.txt

标准输出将转到日志文件，标准derr(相同的数据)将显示在控制台上。
