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。

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

如果你的windows环境路径中有cygwin，你可以使用:

 dir > a.txt | tail -f a.txt

我想对撒克逊德鲁斯的精彩回答进行一点扩展。

如上所述，您可以重定向当前目录中的可执行文件的输出，如下所示:

powershell ".\something.exe | tee test.txt"

但是，这只将stdout记录到test.txt。它也不记录stderr。

最明显的解决方法是使用如下内容:

powershell ".\something.exe 2>&1 | tee test.txt"

然而，这并不适用于所有的前任。一些东西。前任们会把2>&1解释为争吵而失败。正确的解决方案是在something.exe及其开关和参数周围只使用撇号，如下所示:

powershell ".\something.exe --switch1 --switch2 … arg1 arg2 …" 2^>^&1 ^| tee test.txt

但是请注意，在这种情况下，您必须转义特殊的cmd-shell字符“>&|”，每个字符都有一个“^”，这样它们只能由powershell解释。

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
