这样的东西能满足你的需要吗?

%DATE%_%TIME% > c:\a.txt & type c:\a.txt
ipconfig >> c:\a.txt & type c:\a.txt
ping localhost >> c:\a.txt & type c:\a.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

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.

这是可行的，尽管它有点丑陋:

dir >_ && type _ && type _ > a.txt

它比其他一些解决方案更灵活一些，因为它是一条一条地工作的，所以您也可以使用它来追加。我在批处理文件中经常使用这种方法来记录和显示消息:

ECHO Print line to screen and log to file.  >_ && type _ && type _ >> logfile.txt

是的，您可以只重复ECHO语句(一次用于屏幕，第二次重定向到日志文件)，但这看起来同样糟糕，并且存在一些维护问题。至少这样您就不必在两个地方对消息进行更改。

注意_只是一个简短的文件名，所以你需要确保在批处理文件的末尾删除它(如果你使用的是批处理文件)。

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
)
