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?

我发现

dir > a.txt | type a.txt

没有工作(仅dir列表的前几行-怀疑某种进程分叉和第二部分,'type'命令在可怕的列表完成之前终止?), 所以我用了:

dir > z.txt && type z.txt

顺序命令,一个在第二个开始之前完成。

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

这是实时工作,但也是一种丑陋和性能缓慢。也没有经过很好的测试:

@echo off
cls
SET MYCOMMAND=dir /B
ECHO File called 'test.bat' > out.txt
for /f "usebackq delims=" %%I in (`%MYCOMMAND%`) do (
  ECHO %%I
  ECHO %%I >> out.txt
) 
pause

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。

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.

如果你的windows环境路径中有cygwin,你可以使用:

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