[文本处理] [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

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run   
→\SigmatelSysTrayApp 
→\UIUCU 
→\KAV50 
→\FIPExpert 
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run 
→\DAEMON Tools-1033 
→\yassistse 
→\YLive.exe 
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\Run
→\config.exe COPY

如何生成
2.txt:

 
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 
 COPY

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# batpro

@echo off
SetLocal EnableDelayedExpansion
For /F "tokens=*" %%i IN (test.txt) Do (
    set "str=%%i"
    if "!str:~,1!" equ "→" (
       if defined var (echo !var!&echo %%i) ELSE echo %%i
    ) else set var=%%i
)
pauseCOPY

CrLf

借用 terse 的代码：

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

不符合题意

CrLf

4# batpro

搞错了...那样更简单的了：

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

谢谢提醒，用你的代码，我自己写了个：

@echo off
cd.>temp_1.txt
SetLocal EnableDelayedExpansion
For /F "tokens=*" %%i IN (1.txt) Do (
    set "str=%%i"
    if "!str:~,1!" equ "→" (
       if defined var (echo !var!&echo %%i) ELSE echo %%i
    ) else set var=%%i
)>>temp_1.txt
@echo off>temp_2.txt&set n=1
FOR /f "delims=" %%1 in (temp_1.txt) do (
2>nul    set /a n+=1,f=n%%2,1/f&&echo,%%1||set/p=%%1<nul
) >>temp_2.txt
cd.>2.txt
for /f "tokens=*" %%i in (temp_2.txt) do echo,%%i>>2.txtCOPY

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

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

mstsc

好强大啊。for用的地方好多啊，一定要把for弄清楚怎么用
