这将有助于重定向STDOUT和STDERR

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%

如果你想在屏幕上真正看到一些东西，下面的步骤会有所帮助——即使批处理文件被重定向到一个文件。如果重定向到一个文件，也可以使用设备CON

例子:

ECHO first line on normal stdout. maybe redirected
ECHO second line on normal stdout again. maybe redirected
ECHO third line is to ask the user. not redirected  >CON
ECHO fourth line on normal stdout again. maybe redirected

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。

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.

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
