如何在Windows命令提示符中运行命令行应用程序,同时显示输出并将输出重定向到文件?

例如,如果我要运行命令dir > test.txt,这将把输出重定向到一个名为test.txt的文件,而不显示结果。

我如何写一个命令来显示输出并将输出重定向到Windows命令提示符中的文件,类似于Unix上的tee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");

发送输出到控制台,附加到控制台日志,从当前命令删除输出

dir  >> usb-create.1 && type usb-create.1 >> usb-create.log | type usb-create.1 && del usb-create.1

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
)

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.

Mtee是一个小型实用程序,它非常适合这个目的。它是免费的,源代码是开放的,而且很好用。

你可以在http://www.commandline.co.uk上找到它。

在批处理文件中用于显示输出并同时创建日志文件,语法如下所示:

    someprocess | mtee /+ mylogfile.txt

其中/+表示附加输出。

当然,这假设您已经将mtee复制到PATH中的文件夹中。

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。
