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。

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.

下面是我使用的一个基于其他答案的例子

@echo off
REM SOME CODE
set __ERROR_LOG=c:\errors.txt
REM set __IPADDRESS=x.x.x.x

REM Test a variable
if not defined __IPADDRESS (
     REM Call function with some data and terminate
     call :TEE %DATE%,%TIME%,IP ADDRESS IS NOT DEFINED
     goto :EOF
)

REM If test happens to be successful, TEE out a message and end script.
call :TEE Script Ended Successful
goto :EOF


REM THE TEE FUNCTION
:TEE
for /f "tokens=*" %%Z in ("%*") do (
     >  CON ECHO.%%Z
     >> "%__ERROR_LOG%" ECHO.%%Z
     goto :EOF
)

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。

就像unix一样。

目录 |茶A.txt

在windows XP上，它需要安装mksnt。

它显示在提示符上，并附加到文件中。

为了扩展davor的答案，你可以像这样使用PowerShell:

powershell "dir | tee test.txt"

如果你试图重定向当前目录下的exe的输出，你需要在文件名上使用。\，例如:

powershell ".\something.exe | tee test.txt"
