[已解决]批处理如何将文本中指定特征的行分别与其下多行字符串合并

batpro

这样处理文本：补充完整路径
在1.txt中有

1. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run   
   
2. →\SigmatelSysTrayApp
   
3. →\UIUCU
   
4. →\KAV50
   
5. →\FIPExpert
   
6. HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
   
7. →\DAEMON Tools-1033
   
8. →\yassistse
   
9. →\YLive.exe
   
10. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\Run
    
11. →\config.exe
    

复制代码

如何生成
2.txt:

1. 
   
2. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run→\SigmatelSysTrayApp
   
3. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run→\UIUCU
   
4. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run→\KAV50
   
5. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run→\FIPExpert
   
6. 
   
7. HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run→\DAEMON Tools-1033
   
8. HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run→\yassistse
   
9. HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run→\YLive.exe
   
10. 
    
11. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\Run→\config.exe
    

复制代码

说明：手工操作过程是：先剪切→\归属的注册表路径，在复制到各自对应的下方

1. 
   
2. @echo off
   
3. SetLocal EnableDelayedExpansion
   
4. For /F "tokens=*" %%i IN (test.txt) Do (
   
5.     set "str=%%i"
   
6.     if "!str:~,1!" equ "→" (
   
7.        if defined var (echo !var!&echo %%i) ELSE echo %%i
   
8.     ) else set var=%%i
   
9. )
   
10. pause

CrLf

借用 terse 的代码：

1. @Echo Off&SetLocal EnableDelayedExpansion
   
2. (For /F "tokens=*" %%i IN (1.txt) Do (
   
3.     set "str=%%i"
   
4.     if "!str:~1,1!" equ "" (
   
5.        if defined var echo; & set<nul /p=!var! & set var=
   
6.        set /p"=%%i"<nul
   
7.     ) else set var=!str!
   
8. ))>2.txt
   
9. pause

不符合题意

CrLf

4# batpro

搞错了...那样更简单的了：

1. @Echo Off&SetLocal EnableDelayedExpansion
   
2. (For /F "tokens=*" %%i IN (1.txt) Do (
   
3.     if "%%~pi"=="%~p0→" (
   
4.        echo !var!%%i
   
5.     ) else set var=%%i
   
6. ))>2.txt
   
7. pause

谢谢提醒，用你的代码，我自己写了个：

1. @echo off
   
2. cd.>temp_1.txt
   
3. SetLocal EnableDelayedExpansion
   
4. For /F "tokens=*" %%i IN (1.txt) Do (
   
5.     set "str=%%i"
   
6.     if "!str:~,1!" equ "→" (
   
7.        if defined var (echo !var!&echo %%i) ELSE echo %%i
   
8.     ) else set var=%%i
   
9. )>>temp_1.txt
   
10. @echo off>temp_2.txt&set n=1
    
11. FOR /f "delims=" %%1 in (temp_1.txt) do (
    
12. 2>nul    set /a n+=1,f=n%%2,1/f&&echo,%%1||set/p=%%1<nul
    
13. ) >>temp_2.txt
    
14. cd.>2.txt
    
15. for /f "tokens=*" %%i in (temp_2.txt) do echo,%%i>>2.txt

目前的问题是怎么去除“Run” 与  “→\”前的空格
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run   →\SigmatelSysTrayApp
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run   →\UIUCU
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run   →\KAV50
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run   →\FIPExpert
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run →\DAEMON Tools-1033
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run →\yassistse
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run →\YLive.exe
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\Run→\config.exe

恩，好代码，但是怎么，去除空格呢

CrLf

6# batpro


那个空格是 1.txt 中自带的...
如果空格固定为三个，可以把 !var! 换成 !var:~,-3!

谢谢版主，问题解决

另外问一句，假设不知道1.txt里面自动的空格是多少，有其他方法么？【因为处理文本时也可能因为各种原因出现这样的情况】

CrLf

1. @Echo Off&SetLocal EnableDelayedExpansion
   
2. (For /F "tokens=*" %%i IN (1.txt) Do (
   
3.     if "%%~pi"=="%~p0→" (
   
4.        echo !var:%cd%\=!→\%%~nxi
   
5.     ) else set var=%%~fi
   
6. ))>2.txt
   
7. pause
