我在我的大多数机器上安装perl，所以答案使用perl: tee.pl

my $file = shift || "tee.dat";
open $output, ">", $file or die "unable to open $file as output: $!";
while(<STDIN>)
{
    print $_;
    print $output $_;
}
close $output;

目录| perl tee.pl 或 目录| perl tee.pl Dir .bat

粗糙且未经检验。

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

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

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。

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

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.
