I have written a batch script to find and replace a string in a text file. Following is my script.
@echo off &setlocal
set "search=%1"
set "replace=%2"
set "textfile=Input.txt"
set "newfile=Output.txt"
(for /f "delims=" %%i in (%textfile%) do (
set "line=%%i"
setlocal enabledelayedexpansion
set "line=!line:%search%=%replace%!"
echo(!line!
endlocal
))>"%newfile%"
del %textfile%
rename %newfile% %textfile%
I am able to replace the word successfully.
But i dont want to create Output.txt and then rename it the original file..
Please help me out for editing a text file without redirecting the output to a new file..
This question is related to
batch-file
replace
@echo off
setlocal enableextensions disabledelayedexpansion
set "search=%1"
set "replace=%2"
set "textFile=Input.txt"
for /f "delims=" %%i in ('type "%textFile%" ^& break ^> "%textFile%" ') do (
set "line=%%i"
setlocal enabledelayedexpansion
>>"%textFile%" echo(!line:%search%=%replace%!
endlocal
)
for /f
will read all the data (generated by the type
comamnd) before starting to process it. In the subprocess started to execute the type
, we include a redirection overwritting the file (so it is emptied). Once the do
clause starts to execute (the content of the file is in memory to be processed) the output is appended to the file.
