for replacement in dos batch you can see the post here for sugestion.

if you want to roll your own, you can use for loop to go over your file, search for the string and replace accoridingly. you can see the dostip site for various topic on string manipulation such as this .

I see you have Java, here's a progarm you can use to replace your line

Code: Select all

import java.io.*;
import java.util.Scanner;
public class Replace {
   
   public static void main(String[] args){
      if ( args.length != 3 ){
         System.out.println("Usage: java Replace [string] [=value] [config]") ;
         System.exit(1);
      }
      String str = args[0];            /* get the string */
      String value = args[1];            /* get the value to change to */
      String fileName = args[2];         /* file name */
      try{
         Scanner scan = new Scanner ( new File( fileName ) );
         while( scan.hasNextLine() ){
            String myLine = scan.nextLine();
            if ( myLine.indexOf( str  ) != -1 ){               
               myLine = str + "=" + value; 
            }
            System.out.println( myLine );
         }
      }catch (FileNotFoundException ex){
         ex.printStackTrace();
      }
   }
}

compile it and use it (in a batch) as

Code: Select all

java Replace "deployment.javaws.jre.1.args" "new value" config_file > temp
ren temp config_file

This uses a helper batch file called `repl.bat` - download from: https://www.dropbox.com/s/qidqwztmetbvklt/repl.bat

Place `repl.bat` in the same folder as the batch file or in a folder that is on the path.

Code: Select all

@echo off
type "file.cfg" | repl "(deployment.javaws.jre.0.enabled=)true" "$1false" | repl "(deployment.javaws.jre.1.args=).*" "$1-Xms512m -Xmx768m \u00A8CXX\:permSize\=128m -XX\:MaxPermSize\=256m" >"newfile.cfg"
pause

you say you install java so i assume you know Java. To compile Java program you need to use the javac command. After that its just place the code below in a batch

Code: Select all

java Replace "deployment.javaws.jre.1.args" "new value" config_file > temp
ren temp config_file
java Replace "deployment.javaws.jre.0.enabled" "false" config_file > temp
ren temp config_file

if not, then just try the solution foxidrive did. he has done everything for you.
