如何对文本进行分段处理? - 中国DOS联盟论坛

如一个文本文件含有大量的:$12,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,(内容不定)

如何指定字符数进行分段,如:
$23,$32,$23,$32,$23,$32,$23,$32,
$23,$32,$23,$32,$23,$32,$23,$32,
$23,$32,$23,$32,$23,$32,$23,$32,
$23,$32,$23,$32,$23,$32,$23,$32,
$23,$32,$23,$32,$23,$32,$23,$32,
$23,$32,$23,$32,$23,$32,$23,$32,
$23,$32,$23,$32,$23,$32,$23,$32,
$23,$32,$23,$32,$23,$32,$23,$32,
$23,$32,$23,$32,$23,$32,$23,$32,

设置一个计数器N，n从0开始计数，
1. 以“，”为分界符，for /f "delims=," %%i in (a.txt) do (set /a n+=1
2. 如果n<8, 执行set var=%var%,%%i. 如果n=8，执行echo %var%,%%i>>b.txt，然后n重新归0
3.到达文件末尾，跳出循环，再执行一次echo %var%,%%i>>b.txt.
可以了。

@echo off
set str=$12,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,$23,$32,
:agn
set/p=%str:~,32%<nul
echo.
if not "%str:~32%"=="" (set str=%str:~32%&goto :agn)
pause
