标题: 两个文本跳行输出（难题） [打印本页]
作者: bat-zw 时间: 2008-4-1 03:42 标题: 两个文本跳行输出（难题）
===============================================
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

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

set __%%a=%%b&set max=%%a
)

set ++%%a=%%b&set str=%%a
)
if %str% gtr %max% set max=%str%

作者: bat-zw 时间: 2008-4-1 12:09 标题: 不在一个循环中的解决方案：
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。

想知道多少行还不简单
列出两个行后，进行比较不就行了?

作者: ansipeter 时间: 2008-4-1 13:52
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
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
作者: huahua0919 时间: 2008-4-1 14:07
@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

if %max% leq 0 (set/a max=max1) else (set/a max=max2-max1)

findstr %%a: c.txt >>d.txt
)
for /f "delims=: tokens=1*" %%a in (d.txt) do (

)
这个总应该行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

你的和我一楼的代码效果一样，会丢掉行数多的txt中多出的行。
作者: ansipeter 时间: 2008-4-1 14:51
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
作者: terse 时间: 2008-4-1 16:35
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

不好意思，为了得到提高，本人虽然水平有限，还是试着解释这段代码如下：
第一个for循环表示从a.txt中依次读取每行，每读取一行就把这行添加输入到c.txt中然后跳转到第二个for循环中；
第二个for循环的意思是依次读取b.txt中每一行，每读一行就把存在于循环中%%i变量(第二个for循环的%%i)，在b.txt中这行中查找一次,如果没发现就把这一行改变变量名为A并添加输入到c.txt中，然后结束再开始第一个for循环，这样后面的每次循环就不会查找这一行了（其变量名为A而不是%%i）；
而当第一个大循环也就是第一和第二个for循环结束后，便开始了第三个for语句的循环，在这个for循环中就是一行行地对b.txt查找在当前循环中是否有变量%%i（同样行，其余的行的变量名都变成A了）的存在，如没有就添加输入到c.txt中。
真的好难解释啊！！！！！！！！！！！！
总结：trse巧妙的将三个for循环中的变量都命名为%%i，同时反复运用 if (not) defined语句进行查找识别，成功的实现了对a.txt和b.txt跳行并不丢失行的输出，实在是高，佩服！！！

原来是在不知道哪个文件行数多的情况下
如此把2楼代码稍作修改即可达到楼主的要求
:
@echo off&cd.>c.txt
set max=-1
for /f "delims=" %%a in (1.txt) do (
>>c.txt echo %%a&set /a max+=1
call :loop %%max%%
)
set /a max+=1
set flag=a
:loop
if %max% equ 0 (set skip=) else set "skip=skip=%max%"
for /f "%skip% delims=" %%i in (2.txt) do (
>>c.txt echo %%i
if not defined flag goto :eof
)
if not defined flag (goto :eof) else start c.txt&exit
另外： 2 楼的第一个代码到底哪里不行？怎么不通用？set max=-1
for /f "delims=" %%a in (1.txt) do (
>>c.txt echo %%a&set /a max+=1
call :loop %%max%%
)
set /a max+=1
set flag=a
:loop
if %max% equ 0 (set skip=) else set "skip=skip=%max%"
for /f "%skip% delims=" %%i in (2.txt) do (
>>c.txt echo %%i
if not defined flag goto :eof
)
if not defined flag (goto :eof) else start c.txt&exit

14楼的思路的确奇妙，令人佩服！
不过还有个小问题，如果 b.txt 中有相同的行，就会出错。

for /f "%n% delims=" %%i in (b.txt) do echo %%i
pause
goto :eof
:loop
for /f "%n% tokens=1* delims=:" %%i in ('findstr /n .* "b.txt"') do set n=skip=%%i &echo %%j&goto :eof

for /f "%n% tokens=1* delims=:" %%i in ('findstr /n .* "b.txt"') do set n=skip=%%i &echo %%j&goto :eof
使用"delims=:" "findstr /n" "%%n=skip=%%i" 把%%i变量变为行号，思路的确是太广了。
