Search and replace string inside text file - new-line fix

[BoQsc]

Hey everybody, i need some help again.
I have this script:

Code: Select all

@echo off
setlocal enabledelayedexpansion
set INTEXTFILE=test.txt
set OUTTEXTFILE=test_out.txt
set SEARCHTEXT=bath
set REPLACETEXT=hello

for /f "tokens=1,* delims=¶" %%A in ( '"type %INTEXTFILE%"') do (
SET string=%%A
SET modified=!string:%SEARCHTEXT%=%REPLACETEXT%!

echo !modified! >> %OUTTEXTFILE%
)
del %INTEXTFILE%
rename %OUTTEXTFILE% %INTEXTFILE%

Everything is nice and clear with it, but i'm thinking if there is way to modify script, so that in the output file the new-lines (those that are made using Enter button) won't be deleted?

I'm not sure what he means, squashman.

BoQsc, can you please describe it a little more?

EDITED again: Ahh, you want to preserve the blank lines.

Exactly, thanks for the comment good guy foxidrive, that corrects me.

Squashman, it seems that one symbol (^) is added after i parse the text file.
Is there any way to make it happen to disappear from output?

This is original file:

Code: Select all

asdkasldjlkasdklasdplease        
asmdasmdlplease  please       
  
      (for /f "delims=" %%i in ('findstr /n "" "%textfile%"') do (       

This is text file after parse:

Code: Select all

asdkasldjlkasdklasdhello       
asmdasmdlhello  hello      

      (for /f "delims=" %%i in ('findstr /n "^" "%textfile%"') do (      

Error is in this line:

(for /f "delims=" %%i in ('findstr /n "^" "%textfile%"') do (

It works ok here. Show your code and explain your problem again.

I edited it to include a blank line as well.

Code: Select all

d:\abc>a.bat
1:asdkasldjlkasdklasdhello
2:
3:asmdasmdlhello  hello
d:\abc>type a.bat
@echo off

set "textfile=123.txt"
(
echo asdkasldjlkasdklasdhello
echo(
echo asmdasmdlhello  hello
)>"%textfile%"

(for /f "delims=" %%i in ('findstr /n "^" "%textfile%"') do (      echo %%i ) )

Here is script that i use now:

Code: Select all

@echo off
:substitute OldStr NewStr File -- substitutes a string in a text file
::                             -- OldStr [in] - string to be replaced
::                             -- NewStr [in] - string to replace with
::                             -- File   [in] - file to be parsed
:$created 20060101 :$changed 20101122 :$categories FileManipulation
:$source http://www.dostips.com
SETLOCAL DISABLEDELAYEDEXPANSION
del output.txt

set "OldStr=baty"
set "NewStr=monty"
set filetoparse=%0
for /f "tokens=1,* delims=]" %%A in ('"type %filetoparse%|find /n /v """') do (
    set "line=%%B"
    if defined line (
        call set "line=echo.%%line:%OldStr%=%NewStr%%%"
        for /f "delims=" %%X in ('"echo."%%line%%""') do %%~X >> output.txt
    ) ELSE echo.  >> output.txt

)
::baty
EXIT /b

it must scan batch file and replace ::baty with ::monty

The output.txt looks like this:

Code: Select all

@echo off 
:substitute OldStr NewStr File -- substitutes a string in a text file 
::                             -- OldStr [in] - string to be replaced 
::                             -- NewStr [in] - string to replace with 
::                             -- File   [in] - file to be parsed 
:$created 20060101 :$changed 20101122 :$categories FileManipulation 
:$source http://www.dostips.com 
SETLOCAL DISABLEDELAYEDEXPANSION 
del output.txt 
  
set "OldStr=monty" 
set "NewStr=monty" 
set filetoparse=%0 
    set "line=%%B" 
    if defined line ( 
        call set "line=echo.%%line:%OldStr%=%NewStr%%%" 
        for /f "delims=" %%X in ('"echo."%%line%%""') do %%~X >> output.txt 
    ) ELSE echo.  >> output.txt 
  
) 
::monty
EXIT /b 

whole line
for /f "tokens=1,* delims=]" %%A in ('"type %filetoparse%|find /n /v """') do (
has gone...

also, how to make that OldStr=baty will stay untouched while ::baty changing to ::monty?

d:\abc>a.bat

@echo off

set "textfile=123.txt"
(
echo asdkasldjlkasdklasdhello
echo(
echo asmdasmdlhello  hello
)>"%textfile%"

(for /f "delims=" %%i in ('findstr /n "^" "%textfile%"') do (      echo %%i ) )

The echo method is not what i'm searching for. I can't add echo to each line, cause it brokes some things.
Anyone have any idea on how to remove these line numbers?

Original:

Code: Select all

@echo off
asdkasldjlkasdklasdhello   

asmdasmdlhello  hello      

   (for /f "delims=" %%i in ('findstr /n "^" "%textfile%"') do test
     
     pause

Output:

Code: Select all

1:@echo off
2:asdkasldjlkasdklasdtest   
3:
4:asmdasmdltest  test      
5:
6:   (for /f "delims=" %%i in ('findstr /n "^" "%textfile%"') do test
7:     
8:     pause

The code i use is here:

Code: Select all

@echo off &setlocal
set "search=hello"
set "replace=test"
set "textfile=batch_code.bat"
set "newfile=new.bat"

(for /f "delims=" %%i in ('findstr /n "^" "%textfile%"') do (
    set "line=%%i"
    setlocal enabledelayedexpansion
    set "line=!line:%search%=%replace%!"
    echo(!line!
    endlocal
))>"%newfile%"
type "%newfile%"

It was only to demonstrate that the syntax in the FOR loop works fine,
and you had removed the tokens part - and I used what you had posted.

If you don't show the real input and output text, or explain it well, it's hard to give you code that will work.
