The meaning of this title is that, for example, when the xcopy command is executed, many execution results will be displayed on the screen:

---------------------------------------
\\192.168.1.1\update\1.txt
\\192.168.1.1\update\2.txt
\\192.168.1.1\update\3.txt
3 files copied
---------------------------------------

If I need to save this command result to d:\a.txt, so I used xcopy ....>d:\a.txt, but the result is that the above execution results will not be displayed on the screen. Although now I can add a line at the end type d:\a.txt to output the just result on the screen, but it has a lag effect. And it is not the same as before that every time xcopy a file will dynamically display the execution result on the screen.

Now I want to ask if there is a statement that can not affect the display result on the screen and at the same time save the result to a file.

This can be done through tools that provide this function, such as TEE. For example, use the following syntax:

XCOPY .... | TEE D:\A.TXT

This not only does not affect the display of the result on the screen, but also can save the result to one (or more) files.

Function description: Read data from standard input and output its content to a file.
Syntax: tee
Supplementary instructions: The tee command reads data from the standard input device, outputs its content to the standard output device, and saves it as a file at the same time. We can use tee to save the data imported by the pipeline into a file, and even save several files at one time.
Parameters: -a Append to the end of the existing file instead of overwriting it. If the file name given to the tee command already exists, it will overwrite the content of the file by default. With this parameter, the data will be added to the end of the file content instead of deleting the original content.
　　　　　　　-i Ignore interrupt signals
　　　　　　　--help Online help
　　　　　　　--version Display version information
Examples:
List the content of the text file slayers.story, and copy 3 copies at the same time, with the file names ss-copy1, ss-copy2, ss-copy3 respectively:
$ cat slayers.story |tee ss-copy1 ss-copy2 ss-copy3

-----------------------------------------------------------------------------------------

Unfortunately, I just can't download this software. I don't know which category it is in on DOS Home. Can you tell me the download address?

There are no such software in those websites. The DOS version of TEE is in the attachment:

The same question:

@echo off
MKDIR "..\backup">>%DATE%.log
pause

If the back folder exists, in the dos console window it will display
A subdirectory or file ..\backup already exists.
And the content in %date%.log is empty.
Why is the redirection to the log file not working?

MKDIR "..\backup">>%DATE%.log

Should be changed to:

MKDIR "..\backup" 2>>%DATE%.log
or
MD "..\backup" 2>>%DATE%.log

>> Only redirect standard output, not error output. To redirect error output at the same time, use:

MKDIR "..\backup">>%DATE%.log 2>&1

Why use this?

xcopy ........ 1>con 1>D:\a.txt

Or

xcopy ....... 1>con 1>D:\a.txt 1<&2

Why not?

Can we copy the data of handle 1 to handle 4, then 1 to the screen, and 4 to the file?

Or, use the mode command? It feels not very cool to use third-party tools

Thanks, Wengier. I've copied it down. I'll use it right away.

Also, can anyone help me upload choice.exe? Hehe. I'm using it under XP now. I don't know how to install DOS yet. I've been writing batch scripts under XP for several months.

It doesn't work?

These of course don't work. If you really want to achieve it without using third-party tools, it's better to do it like this:
xcopy ....... >a.txt | type a.txt

Thank you Wengier. I have copied it down. Use it immediately.

Also who can help me to put choice.exe also pass on, he he. I am now under XP to use. Also will not install dos. For a few months...

The choice command is basically only use in the pure DOS to compare useful, under XP use set /p to replace.

Why does a new window pop up when I use tee in the cmd of xp, showing a line of garbled code and then closing? I guess this line of garbled code must be "1 file(s) copied". What do I need to install to remove the garbled code?

COPY d:\dos\end.txt d:\ | TEE D:\A.TXT

I myself tried the above command, but didn't find any new window popping up showing a line of garbled code.

Hey. I ran Tee under the cmd in XP and it seems that Chinese names are not supported. When encountering paths with Chinese names, it shows as ???. What should I do about this?

The command "chcp 936" can switch the current display code page to Simplified Chinese.
