China DOS Union

### Requirements: Organize a.txt by breaking lines at periods, that is, concatenate lines without periods with the next line, and break lines with periods at the period. Note: There may be several consecutive lines without periods, or multiple periods in one line. No need to consider special character issues. Of course, the premise is that you cannot concatenate all the content of a.txt into one variable. (Because the character limit of the variable is limited) See who has the most concise and efficient code, plus points..!
### Content of a.txt:
```
Batch processing files (Batch File, referred to as BAT files) are a most commonly used executable file under DOS. It has flexible operability and can adapt to various complex computer operations. The so-called batch processing means automatically executing several specified DOS commands or programs in a prescribed order.
That is to summarize the commands executed one by one, execute them in batches, and the program file can be ported to other computers for operation, so it can greatly save the tediousness of repeatedly entering commands. At the same time, batch processing files also have some programming characteristics. It can flexibly control the execution of the program through extended parameters, so it is very practical in daily work. Batch processing. bat. cmd. Each has its own limitations. Each has its own advantages.

### Summary:
There are many answers, (2nd floor 14th floor 17th floor 19th floor)
The 2nd floor adopts the method of reading character by character, and can handle most special characters, but the efficiency is too low.
The 14th floor created a com file, which is extremely efficient. Unfortunately, I don't understand it, but I have gained knowledge. However, this question is still solved with pure p.
The ideas of the 17th floor and the 19th floor are the same, the code is slightly different, and the efficiency is also good, basically meeting the requirements of the building owner.

Read character by character
@echo off for /f "delims=" %%i in ('findstr /n .* 1.txt') do ( set "str=%%i" setlocal enabledelayedexpansion set str=!str:*:=! call :lp endlocal ) pause&exit :lp if defined str ( set /p= !str:~0,1!<nul if "!str:~0,1!"=="。" echo. set str=!str:~1! goto lp )
Ignore special characters, can also be simplified
@echo off&setlocal enabledelayedexpansion for /f "delims=" %%i in (1.txt) do set str=%%i&call :lp pause&exit :lp set /p= !str:~0,1!<nul if "!str:~,1!"=="。" echo. set str=!str:~1! if defined str goto lp

Reading character by character is indeed an option, but the efficiency will be greatly reduced. Add 5 points.

Can I replace "." with "echo."?

That is to summarize the originally executed commands one by one and execute them in batches, and the program file can be ported to other computers for operation, so it can greatly save the tediousness of repeatedly entering commands.

How is the punctuation of this determined?

setlocal ENABLEDELAYEDEXPANSION for /f "delims=" %%i in (text.txt) do ( set str=%%i set/p=!str!<nul>>temp.txt) for /f "delims=。" %%i in (temp.txt) do (echo %%i。&echo.)>>result.txt
It's a pity that things didn't go as expected. The final result is only one line. Experts, please help modify it. I think the idea is correct.

Has Brother Laotu ever studied the maximum number of characters that can fit in one line of a text file? If it exceeds this limit, is your idea still correct?

Back to the 5th floor

There is no period in the middle, so of course it counts as one sentence.

Is this okay...

@echo off&setlocal enabledelayedexpansion
for /f "delims=" %%a in (a.txt) do set str=!str!%%a
set str=%str:。=。^&echo.^&echo.%
echo %str%
pause>nul

I'm sorry, I forgot to read the question in detail...

Is that a typesetting issue? I just don't understand why the Chinese characters are broken...

If it's VBS: replace "carriage return" with "empty", replace "。" with "。+carriage return"

The LZ doesn't allow this, heh heh.

Under Unix this should work, but under Windows it just doesn't. Thinking...
sed "s/。/。\n/g" a.txt | sed "/。$/!s/\n//g"

It's not breaking at the "中" character, it's the forum automatically wrapping it.
So in my sample, empty lines represent line breaks. Is that clear?

Change the idea

@echo off chcp 437 >nul & graftabl 936 >nul echo Bj@jzh`0X-`/PPPPPPa(DE(DM(DO(Dh(Ls(Lu(LX(LeZRR]EEEUYRX2Dx=>sbs2.com echo 0DxFP,0Xx.t0P,=XtGsB4o@$?PIyU WwX0GwUY Wv;ovBX2Gv0ExGIuht6>>sbs2.com echo ?@}IKuNWpe~Fpe?FNHlF?wGMECIQqo{Ox{T?kPv@jeoSeIlRFD@{AyEKj@>>sbs2.com echo iqe~1NeAyR?mHAG~BGRgB{~H?o~TsdgCYqe?HR~upkpBG?~slJBCyA?@xA>>sbs2.com echo LZp{xq`Cs?H

I think it might be a bug in Notepad. Sometimes it works fine, but when you close it and open it again, the Notepad will have a break in the middle.
