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.

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
另请参阅良好的重定向说明:http://www.p-dd.com/chapter7-page14.html
有一个Win32端口的Unix tee命令,就是这样做的。见http://unxutils.sourceforge.net/或http://getgnuwin32.sourceforge.net/
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%

这将有助于重定向STDOUT和STDERR
