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");

我能够找到一个解决方案/工作区重定向输出到一个文件,然后到控制台:
dir > a.txt | type a.txt
其中dir是需要重定向输出的命令,a.txt是存储输出的文件。
看看这个:wintee
不需要cygwin。
不过,我确实遇到并报告了一些问题。
您还可以检查unxutils,因为它包含tee(不需要cygwin),但注意这里的输出EOL是类似unix的。
最后,但并非最不重要的是,如果你有PowerShell,你可以尝试Tee-Object。在PowerShell控制台中输入get-help tee-object获取更多信息。
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.
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。
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。
