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 know this is a very old topic, but in previous answers there is not a full implementation of a real time Tee written in Batch. My solution below is a Batch-JScript hybrid script that use the JScript section just to get the output from the piped command, but the processing of the data is done in the Batch section. This approach have the advantage that any Batch programmer may modify this program to fit specific needs. This program also correctly process the output of CLS command produced by other Batch files, that is, it clear the screen when CLS command output is detected.

@if (@CodeSection == @Batch) @then


@echo off
setlocal EnableDelayedExpansion

rem APATee.bat: Asynchronous (real time) Tee program, Batch-JScript hybrid version
rem Antonio Perez Ayala

rem The advantage of this program is that the data management is written in Batch code,
rem so any Batch programmer may modify it to fit their own needs.
rem As an example of this feature, CLS command is correctly managed

if "%~1" equ "" (
   echo Duplicate the Stdout output of a command in the screen and a disk file
   echo/
   echo anyCommand ^| APATee teeFile.txt [/A]
   echo/
   echo If /A switch is given, anyCommand output is *appended* to teeFile.txt
   goto :EOF
)

if "%2" equ ":TeeProcess" goto TeeProcess

rem Get the output of CLS command
for /F %%a in ('cls') do set "cls=%%a"

rem If /A switch is not provided, delete the file that receives Tee output
if /I "%~2" neq "/A" if exist %1 del %1

rem Create the semaphore-signal file and start the asynchronous Tee process
echo X > Flag.out
if exist Flag.in del Flag.in
Cscript //nologo //E:JScript "%~F0" | "%~F0" %1 :TeeProcess
del Flag.out
goto :EOF

:TeeProcess
   rem Wait for "Data Available" signal
   if not exist Flag.in goto TeeProcess
   rem Read the line sent by JScript section
   set line=
   set /P line=
   rem Set "Data Read" acknowledgement
   ren Flag.in Flag.out
   rem Check for the standard "End Of piped File" mark
   if "!line!" equ ":_EOF_:" exit /B
   rem Correctly manage CLS command
   if "!line:~0,1!" equ "!cls!" (
      cls
      set "line=!line:~1!"
   )
   rem Duplicate the line in Stdout and the Tee output file
   echo(!line!
   echo(!line!>> %1
goto TeeProcess


@end


// JScript section

var fso = new ActiveXObject("Scripting.FileSystemObject");
// Process all lines of Stdin
while ( ! WScript.Stdin.AtEndOfStream ) {
   // Read the next line from Stdin
   var line = WScript.Stdin.ReadLine();
   // Wait for "Data Read" acknowledgement
   while ( ! fso.FileExists("Flag.out") ) {
      WScript.Sleep(10);
   }
   // Send the line to Batch section
   WScript.Stdout.WriteLine(line);
   // Set "Data Available" signal
   fso.MoveFile("Flag.out", "Flag.in");
}
// Wait for last "Data Read" acknowledgement
while ( ! fso.FileExists("Flag.out") ) {
      WScript.Sleep(10);
}
// Send the standard "End Of piped File" mark
WScript.Stdout.WriteLine(":_EOF_:");
fso.MoveFile("Flag.out", "Flag.in");

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"

dir 1 > a . txt 2 > &1 |式a . txt。

这将有助于重定向STDOUT和STDERR

另一种变化是分割管道，然后根据需要重新定向输出。

    @echo off
    for /f "tokens=1,* delims=:" %%P in ('findstr /n "^"') do (
      echo(%%Q
      echo(%%Q>&3
    )
    @exit/b %errorlevel%

将上述内容保存到.bat文件中。它还将文件流1上的文本输出分割到文件流3，您可以根据需要重定向。在下面的例子中，我将上面的脚本称为splitPipe.bat…

    dir | splitPipe.bat  1>con  2>&1  3>my_stdout.log

    splitPipe.bat 2>nul < somefile.txt

这是可行的，尽管它有点丑陋:

dir >_ && type _ && type _ > a.txt

它比其他一些解决方案更灵活一些，因为它是一条一条地工作的，所以您也可以使用它来追加。我在批处理文件中经常使用这种方法来记录和显示消息:

ECHO Print line to screen and log to file.  >_ && type _ && type _ >> logfile.txt

是的，您可以只重复ECHO语句(一次用于屏幕，第二次重定向到日志文件)，但这看起来同样糟糕，并且存在一些维护问题。至少这样您就不必在两个地方对消息进行更改。

注意_只是一个简短的文件名，所以你需要确保在批处理文件的末尾删除它(如果你使用的是批处理文件)。
