是把文本平分为 5 份，还是两行为一份？如果是后者：

@echo off
set file="abc.txt"

for %%a in (%file%) do set "dpn=%%~dpna" & set "x=%%~xa"
set /a line=0, m=0, n=0
setlocal enabledelayedexpansion
for /f "usebackq delims=" %%a in (!file!) do (
  set /a line+=1, m=line%%2, n+=m
  if !m!==0 (set last=%%a) else (echo !last!&echo %%a)>"!dpn!__!n!!x!"
)
if !m!==0 echo !last!>"!dpn!__!n!!x!"

分割 Test.txt，每份 100 行，文件名是 Test_aa、Test_ab、Test_ac ...：

split.exe -l 100 Test.txt Test_
复制代码

@echo off
set file="Test.txt"
set per=100

for %%a in (%file%) do set "dpn=%%~dpna" & set "x=%%~xa"
set /a count=per-1, n=0
setlocal enabledelayedexpansion
for /f "usebackq delims=" %%a in (!file!) do (
  set /a count+=1, n=count/per
  echo %%a>>"!dpn!__!n!!x!"
)
