Write batch variable into specific line in a text file

batch-file, text

Solution

I figured it out!! Here is the code for anyone else who might ever need it.

@echo off
setlocal enableextensions enabledelayedexpansion

set inputfile=variables.txt

set tempfile=%random%-%random%.tmp

copy /y nul %tempfile%

set line=0

for /f "delims=" %%l in (%inputfile%) do (
    set /a line+=1
    if !line!==4 (
        echo WORDS YOU REPLACE IT WITH>>%tempfile%
    ) else (
        echo %%l>>%tempfile%
    )
)

del %inputfile%
ren %tempfile% %inputfile%

endlocal

Problem

I have a batch file where I need to write a variable into a specific line of a text file and override what is all ready in that line. I have the code to read specific lines from the file maybe I could switch it around to also write? Reading lines code: ``` setLocal EnableDelayedExpansion for /f "tokens=* delims= " %%a in (variables.txt) do ( set /a N+=1 set v!N!=%%a ) set variable1=!v1! set variable2=!v2! set variable3=!v3! set variable4=!v4! ``` I've tried to add echo `%variable1% > !v4!` something like that but it doesn't work.
