不幸的是，没有这样的东西。

Windows控制台应用程序只有一个输出句柄。(嗯，有两个STDOUT, STDERR，但在这里不重要)>重定向输出通常写入控制台句柄到文件句柄。

如果你想要有某种多路复用，你必须使用一个外部应用程序，你可以将输出转移到它。然后，该应用程序可以再次写入文件和控制台。

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%

如果你在CLI中，为什么不用FOR循环来“DO”你想做的事情:

for /F "delims=" %a in ('dir') do @echo %a && echo %a >> output.txt

Great resource on Windows CMD for loops: https://ss64.com/nt/for_cmd.html The key here is setting the delimeters (delims), that would break up each line of output, to nothing. This way it won't break on the default of white-space. The %a is an arbitrary letter, but it is used in the "do" section to, well... do something with the characters that were parsed at each line. In this case we can use the ampersands (&&) to execute the 2nd echo command to create-or-append (>>) to a file of our choosing. Safer to keep this order of DO commands in case there's an issue writing the file, we'll at least get the echo to the console first. The at sign (@) in front of the first echo suppresses the console from showing the echo-command itself, and instead just displays the result of the command which is to display the characters in %a. Otherwise you'd see:

echo驱动器[x]中的卷为Windows

UPDATE: /F跳过空行，唯一的修复是预过滤输出，向每一行添加一个字符(可能通过命令find使用行号)。在CLI中解决这个问题既不快速也不漂亮。此外，我没有包括STDERR，所以这里捕获错误:

for /F "delims=" %a in ('dir 2^>^&1') do @echo %a & echo %a >> output.txt

重定向错误消息

插入符号(^)用于转义后面的符号，因为命令是一个正在被解释的字符串，而不是直接在命令行中输入它。

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

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
