这会给你一个基本的骨架。根据需要进行调整
@echo off
setlocal enableextensions disabledelayedexpansion
set "nLines=5000"
set "line=0"
for /f "usebackq delims=" %%a in ("passwords.txt") do (
set /a "file=line/%nLines%", "line+=1"
setlocal enabledelayedexpansion
for %%b in (!file!) do (
endlocal
>>"passwords_%%b.txt" echo(%%a
)
)
endlocal
EDITED
正如评论所指出的,4.3GB 的文件很难管理。for /f
需要将整个文件加载到内存中,并且当文件在内存中转换为 unicode 时,所需的缓冲区是此大小的两倍。
这是一个完全临时的解决方案。我还没有在那么高的文件上测试过它,但至少理论上它应该可以工作(除非 5000 行需要大量内存,这取决于行长度)
而且,使用这样的文件会很慢
@echo off
setlocal enableextensions disabledelayedexpansion
set "line=0"
set "tempFile=%temp%\passwords.tmp"
findstr /n "^" passwords.txt > "%tempFile%"
for /f %%a in ('type passwords.txt ^| find /c /v "" ') do set /a "nFiles=%%a/5000"
for /l %%a in (0 1 %nFiles%) do (
set /a "e1=%%a*5", "e2=e1+1", "e3=e2+1", "e4=e3+1", "e5=e4+1"
setlocal enabledelayedexpansion
if %%a equ 0 (
set "e=/c:"[1-9]:" /c:"[1-9][0-9]:" /c:"[1-9][0-9][0-9]:" /c:"!e2![0-9][0-9][0-9]:" /c:"!e3![0-9][0-9][0-9]:" /c:"!e4![0-9][0-9][0-9]:" /c:"!e5![0-9][0-9][0-9]:" "
) else (
set "e=/c:"!e1![0-9][0-9][0-9]:" /c:"!e2![0-9][0-9][0-9]:" /c:"!e3![0-9][0-9][0-9]:" /c:"!e4![0-9][0-9][0-9]:" /c:"!e5![0-9][0-9][0-9]:" "
)
for /f "delims=" %%e in ("!e!") do (
endlocal & (for /f "tokens=1,* delims=:" %%b in ('findstr /r /b %%e "%tempFile%"') do @echo(%%c)>passwords_%%a.txt
)
)
del "%tempFile%" >nul 2>nul
endlocal
EDITED再次强调:以前的代码对于以冒号开头的行将无法正确工作,因为它已在for
用于将行号与数据分开的命令。
作为替代方案,仍然是纯批处理,但仍然很慢
@echo off
setlocal enableextensions disabledelayedexpansion
set "nLines=5000"
set "line=0"
for /f %%a in ('type passwords.txt^|find /c /v ""') do set "fileLines=%%a"
< "passwords.txt" (for /l %%a in (1 1 %fileLines%) do (
set /p "data="
set /a "file=line/%nLines%", "line+=1"
setlocal enabledelayedexpansion
>>"passwords_!file!.txt" echo(!data!
endlocal
))
endlocal
