dir 1 > a . txt 2 > &1 |式a . txt。

这将有助于重定向STDOUT和STDERR

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

这是MTS之前回答的一个变化，但是它增加了一些可能对其他人有用的功能。下面是我使用的方法:

A command is set as a variable, that can be used later throughout the code, to output to the command window and append to a log file, using set _Temp_Msg_Cmd= the command has escaped redirection using the carrot ^ character so that the commands are not evaluated initially A temporary file is created with a filename similar to the batch file being run called %~n0_temp.txt that uses command line parameter extension syntax %~n0 to get the name of the batch file. The output is appended to a separate log file %~n0_log.txt

下面是命令的顺序:

输出和错误消息被发送到临时文件^> %~n0_temp.txt 2^>^&1 临时文件的内容是: 附加到日志文件^&类型%~n0_temp.txt ^>^> %~n0_log.txt 输出到命令窗口^&键入%~n0_temp.txt 删除带有该消息的临时文件^& del /Q /F %~n0_temp.txt

下面是例子:

设置_Temp_Msg_Cmd = ^ > % ~ n0_temp.txt 2 ^ > ^ & 1 ^ & % ~型n0_temp.txt ^ > ^ > % ~ n0_log.txt ^ & % ~型n0_temp.txt ^ & del / Q / F % ~ n0_temp.txt

这样，命令就可以简单地附加在批处理文件中后面的命令之后，看起来更干净:

echo test message %_Temp_Msg_Cmd%

这也可以添加到其他命令的末尾。据我所知，当消息有多行时，它将工作。例如，如果有错误消息，以下命令将输出两行:

net使用M: /D /Y %_Temp_Msg_Cmd%

我刚刚找到了一种方法来使用perl作为替代，例如: CMD1 | perl -ne "print $_;打印STDERR $_;"2 >输出。三通

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。

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.
