两个文本跳行输出（难题） - 中国DOS联盟论坛

===============================================
虽然目前还没有人达到开始的要求主（可能是一个for镶嵌根本做不到），但还是有了比较完美的方案＝＝＝＝＝＝＝＞见14楼，同时本人在17楼对这段代码进行了粗略的分析。
＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
本人苦思多日，终于想到了基本在一个大循环中解决的方案，＝＝＞见25楼
文本1.txt

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
ccccccccccccccccccccccccccccccccccccccc
eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
ggggggggggggggggggggggggggggggggggggggg
wwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww
zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz

文本2.txt

hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii
jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj
nnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn

要求用批处理输出为

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
ccccccccccccccccccccccccccccccccccccccc
iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii
eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj
ggggggggggggggggggggggggggggggggggggggg
nnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn
wwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww
zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz

我写下的如下代码：

@echo off
for /f "tokens=*" %%i in ('findstr /n .* 1.txt') do (
    for /f "tokens=*" %%j in ('findstr /n .* 2.txt') do (   
        set var=%%i
        set str=%%j    
        setlocal enabledelayedexpansion
        if "!var:~,1!"=="!str:~,1!" echo !var:~2,50!&echo !str:~2,50!
        endlocal
    )
)
pause

输出为:

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
ccccccccccccccccccccccccccccccccccccccc
iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii
eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj
ggggggggggggggggggggggggggggggggggggggg
nnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn

丢了1.txt最后两行，搞了好久都没解决，只好请教大家了（注，要在一个循环中解决）。

呵呵，
为何非要在一个循环中完成，你的那个代码，效率是个大问题，1.txt有多少行，就要把2.txt循环多少遍。。。
怎么才算是一个循环啊？我觉得你的这个代码就应该不叫一个循环。所谓一个循环，应该是说只把一个文档循环一次。
另外，1.txt和2.txt的行数不一样，最后1.txt多的行怎么处理？
你给的标准输出，好像也有错误啊，wwwwwwww那一行去哪啦？

:


@echo off
for /f "tokens=1* delims=:" %%a in ('findstr /n .* 1.txt') do (
   set __%%a=%%b&set max=%%a
)
for /f "tokens=1* delims=:" %%a in ('findstr /n .* 2.txt') do (
   set ++%%a=%%b&set str=%%a
)
if %str% gtr %max% set max=%str%
setlocal enabledelayedexpansion
for /l %%a in (1 1 %max%) do (
  if defined __%%a echo !__%%a!
  if defined ++%%a echo !++%%a!
)
pause


@echo off
set max=-1
for /f "delims=" %%a in (1.txt) do (
   echo %%a&set /a max+=1
   call :loop %%max%%
)
pause
:loop
if %max% equ 0 (set skip=) else set "skip=skip=%max%"
for /f "%skip% delims=" %%i in (2.txt) do echo %%i&goto :eof
goto :eof

我的意思是在一个for镶嵌中解决这个问题，不然就谈不上难了，呵呵。


@ECHO OFF
findstr /n .* a.txt>>c.txt
echo.>>c.txt
findstr /n .* b.txt>>c.txt
for /l %%i in (1 1 6) do (
findstr %%i: c.txt >>d.txt
)
for /f "delims=: tokens=1*" %%a in (d.txt) do (
echo %%b>>e.txt
)
del c.txt
del d.txt

还是没达到我最初的想法，但通用性还好，2楼、四楼的代码通用性还不行：
1　实际上我们不可能每次都知道到底1.txt和2.txt哪个的行数多（针对2楼的）
2　我们也不可能每次都知道1.txt和2.txt都有多少行（针对4楼的）
如意见不对，请指正，目的只有一个为了提高。

@echo off
for /f "tokens=*" %%i in ('findstr /n .* 1.txt') do (
    for /f "tokens=*" %%j in ('findstr /n .* 2.txt') do (   
        set var=%%i
        set str=%%j    
        setlocal enabledelayedexpansion
        if "!var:~,2!"=="!str:~,2!" echo !var:~2,50!&echo !str:~2,50!
        endlocal
    )
)
for /f "delims=: tokens=1" %%i in ('findstr /n .* 1.txt') do set n=%%i
for /f "delims=: tokens=1" %%j in ('findstr /n .* 2.txt') do set m=%%j
if %n% equ %m% pause&goto :eof
if %n% lss %m% goto 2
:1
set /a n=%m%
for /f "skip=%n%" %%i in (1.txt) do echo %%i
pause&goto :eof
:2
set /a n=%n%
for /f "skip=%n%" %%j in (2.txt) do echo %%j
pause&goto :eof

想知道多少行还不简单
列出两个行后，进行比较不就行了?

P不容易就换别的嘛。

虽然操作有些麻烦还是可以勉强实现的，不过代码多了点而已，唉


@echo off&setlocal
for /f "delims=: tokens=1*" %%a in ('findstr /n .* 1.txt') do call:ansi %%a "%%b"
goto:eof
:ansi
echo %~2
for /f "delims=: tokens=1*" %%y in ('findstr /n .* 2.txt^|findstr "^%1:.*"') do echo %%z


@ECHO OFF
findstr /n .* a.txt>>c.txt
for /f "delims=: tokens=1" %%i in (c.txt) do set max1=%%i
echo.>>c.txt
findstr /n .* b.txt>>c.txt
for /f "delims=: tokens=1" %%i in (c.txt) do set max2=%%i
set/a max=(max2-max1)-max1
if %max% leq 0 (set/a max=max1) else (set/a max=max2-max1)
for /l %%a in (1 1 %max%) do (
findstr %%a: c.txt >>d.txt
)
for /f "delims=: tokens=1*" %%a in (d.txt) do (
echo %%b>>e.txt
)

这个总应该行

楼上的，你测试了吗？对，我的代码是有些通用性不好，必须在for /f "delims=: tokens=1*" %%a in ('findstr /n .* 1.txt') do call:ansi %%a "%%b"这句放置行多的那个文件，我这里测试通过，如果要是怎么放都可以的话，那添加个判断就可以很好的通用了，唉

我来一个虽然多一FOR 但有效怎么多个%%I
@echo off
for /f "delims=" %%i in (a.txt) do >>c.txt echo %%i&call :loop
for /f "delims=" %%i in (b.txt) do if not defined %%i echo %%i>>c.txt
pause
goto :eof
:loop
for /f "delims=" %%i in (b.txt) do if not defined %%i set %%i=A &>>c.txt echo %%i&goto :eof

上面处理不了b.txt重复行所以改一下:
@echo off
for /f "delims=" %%i in (a.txt) do >>c.txt echo %%i&call :loop
for /f "%n% delims=" %%i in (b.txt) do >>c.txt echo %%i
pause
goto :eof
:loop
for /f "%n% tokens=1* delims=:" %%i in ('findstr /n .* "b.txt"') do set n=skip=%%i &>>c.txt echo %%j&goto :eof
