Find a string and replace specific letters in batch file - string

Question

I have a to create an autosys job to trigger a batch file which would find a specific string and then replace the next 4 characters.
For example if file (with multiple lines) has below content and i am searching for played
the mad fox jumped of the old vine and
played soccer.
I should replace "socc" with "INFA"
I am new to batch files and my lead has been insisting that i do this using a batch file only. Any help would be greatly apprciated.
Thanks,
Joy

Answer 1

#echo off &setlocal
set "search=search string"
set "replace=kordo anstataui"
set "textfile=file.txt"
set "newfile=new.txt"
(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%"

Apparently you are searching for "played " with a space at the end, although your question is a bit vague.
See my hybrid JScript/batch utility called REPL.BAT that does regular expression search and replace. It works on any modern version of Windows from XP onward, and it does not require installation of any 3rd party executeables.
Using REPL.BAT:
type "yourFile.txt"|repl "played ...." "played INFA" >"yourFile.txt.new"
move /y "yourFile.txt.new" "yourFile.txt" >nul

I use this at times: sar.bat
::Search and replace
#echo off
if "%~3"=="" (
echo.Search and replace
echo Syntax:
echo "%~nx0" "filein.txt" "fileout.txt" "regex" "replace_text" [first]
echo.
echo.EG: change the first time apple appears on each line, to orange
echo."%~nx0" "my text old.txt" "my text changed.txt" "apple" "orange" first
echo.
echo.People that are familiar with regular expressions can use some:
echo.
echo.Change every line starting from old (and everything after it^) to new
echo."%~nx0" "my text old.txt" "my text changed.txt" "old.*" "new"
echo.
echo.If [first] is present only the first occurrence per line is changed
echo.
echo.To make the search case sensitive change
echo.IgnoreCase= from True to False
echo.
pause
goto :EOF
)
if "%~5"=="" (set global=true) else (set global=false)
set s=regex.replace(wscript.stdin.readall,"%~4")
>_.vbs echo set regex=new regexp
>>_.vbs echo regex.global=%global%
>>_.vbs echo regEx.IgnoreCase=True
>>_.vbs echo regex.pattern="%~3"
>>_.vbs echo wscript.stdOut.write %s%
cscript /nologo _.vbs <"%~1" >"%~2"
del _.vbs

Get yourself a copy of sed for your OS and call it from a batch file.
sed -e 's/socc/INFA/g' inputFileName > outputFileName

Answer 5

#echo off
setlocal EnableDelayedExpansion
set "search=played "
set replacement=INFA
set numChars=4
set line=the mad fox jumped of the old vine and played soccer.
rem The characters after the equal-signs are Ascii-254
for /F "tokens=1* delims=■" %%a in ("!line:%search%=■!") do (
set "rightPart=%%b"
set "line=%%a%search%%replacement%!rightPart:~%numChars%!"
)
echo !line!
Output:
the mad fox jumped of the old vine and played INFAer.
You must insert previous code into a loop that process the entire file. I left that part as an exercise for you...
