How to output the _final_ screen display from a batch file to a file? - China DOS Union Forum

As the title says.

For example, there is a bat file. After it finishes running and pause is reached, I can Select All in the cmd window, copy it, and save it as text.
What I want is a way to save this text automatically.

An example will make it easier to explain.The example is only for illustration, not a request for a solution to this specific case.
Suppose there is a batch file that converts wav to flac.
flac.exe test.wav
While it runs, the screen keeps updating with the progress. When it finishes, it gives final information such as the final file size and compression ratio. (If that's not clear enough, please look at the pictures.
During run 1:

During run 2:

Final screen display:

This final screen display information is what I want.

If I use 2>log, then the file I get is something like this:

flac 1.2.1, Copyright (C) 2000,2001,2002,2003,2004,2005,2006,2007 Josh Coalson
flac comes with ABSOLUTELY NO WARRANTY. This is free software, and you are
welcome to redistribute it under certain conditions. Type `flac' for details.

wavtest.wav: 3% complete, ratio=0.251
wavtest.wav: 5% complete, ratio=0.280
wavtest.wav: 7% complete, ratio=0.279
...middle omitted
wavtest.wav: 95% complete, ratio=0.450
wavtest.wav: 98% complete, ratio=0.452
wavtest.wav: wrote 4770849 bytes, ratio=0.445

But what I want is what is shown in the final screen display, without so many lines in the middle, in a file in a format like this:

flac 1.2.1, Copyright (C) 2000,2001,2002,2003,2004,2005,2006,2007 Josh Coalson
flac comes with ABSOLUTELY NO WARRANTY. This is free software, and you are
welcome to redistribute it under certain conditions. Type `flac' for details.

wavtest.wav: wrote 4770849 bytes, ratio=0.445

The above example is only for illustration, not a request for a solution to this specific case.

Is there any command or tool that can do this?

Please advise. Thanks.

PS, what I want is to get such a file directly, not to process the log with a tool after it finishes.

Thanks.
But the flac example I gave above was only an example. Using findstr does not seem to work generally for other cases.
Is there a more generally applicable method?

Is it the first three lines and the last line?

Hello. What I want to find is a general solution.
The example here is only for ease of explanation and use.

What I need is what the title says: output the _final_ screen display to a file.

Give another different example and let us see. If the program is supposed to be general, then you have to find what different examples have in common and handle that; otherwise, it can't be written.

Hello.
Let me put it another way.
There is a bat file. After it finishes running and pause is reached, I can Select All in the cmd window, copy it, and save it as text.
What I want is a way to save this text automatically.
What I do not want is a method for how to process the log file after redirecting stderr to a log file.

Thanks for your reply.
But it would be better if you could read the post before replying; it would save both your time and mine.
What I want is not a solution for this specific example.

You really are hard to understand

Could you re-upload the pictures
Upload pictures that can be seen clearly

@echo off
