我想对撒克逊德鲁斯的精彩回答进行一点扩展。

如上所述，您可以重定向当前目录中的可执行文件的输出，如下所示:

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

但是，这只将stdout记录到test.txt。它也不记录stderr。

最明显的解决方法是使用如下内容:

powershell ".\something.exe 2>&1 | tee test.txt"

然而，这并不适用于所有的前任。一些东西。前任们会把2>&1解释为争吵而失败。正确的解决方案是在something.exe及其开关和参数周围只使用撇号，如下所示:

powershell ".\something.exe --switch1 --switch2 … arg1 arg2 …" 2^>^&1 ^| tee test.txt

但是请注意，在这种情况下，您必须转义特殊的cmd-shell字符“>&|”，每个字符都有一个“^”，这样它们只能由powershell解释。

我如何显示和重定向输出 到一个文件。假设我使用dos dir > test.txt，执行此命令 将重定向输出到文件test.txt 不显示结果。如何 写一个命令来显示输出 并将输出重定向到文件使用 DOS，即windows命令提示符，而不是 在UNIX / LINUX。

您可能会发现biterscripting (http://www.biterscripting.com)中的这些命令很有用。

var str output
lf > $output
echo $output                            # Will show output on screen.
echo $output > "test.txt"               # Will write output to file test.txt.
system start "test.txt"                 # Will open file test.txt for viewing/editing.

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

这样的东西能满足你的需要吗?

%DATE%_%TIME% > c:\a.txt & type c:\a.txt
ipconfig >> c:\a.txt & type c:\a.txt
ping localhost >> c:\a.txt & type c:\a.txt
pause

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"
