Batch Scripting / AUTOIT Question

[Deathdefyer2002]

Here is my program:

#include <Constants.au3>

HotKeySet("{ESC}", "Terminate")

$work = Run("cmd", $STDOUT_CHILD) ;

AutoItSetOption("SendKeyDelay", 1)

send(" path=c:\Program Files\WinRAR")

Send ("{ENTER}")

global $text1

global $size

global $test

global $data

for $i2 = 97 to 105

$text1 = $text1 & Chr($i2)

Send("unrar e hamachi.rar > unrar1.txt")

Send ("{ENTER}")

send($text1)

Send ("{ENTER}")

sleep(100)

While 1

$hello= stdoutread($work)

If @error Then ExitLoop

MsgBox(0, "STDOUT read:", $line)

Wend

MsgBox(0,"Text" , $hello)

$size = FileGetSize("unrar1.txt")

if $size < 110 then send("q")

if $size < 110 then Send ("{ENTER}")

if $size < 110 then exitloop

send("cls")

Send ("{ENTER}")

$text1=""

Next

$text1 = Chr($i2-1)

MsgBox(0, "The Password Was", $text1)

filedelete("c:\unrar1.txt")

Func Terminate()

Exit 0

EndFunc

Basically what I'm trying to do is run a brute force unrar attack where it runs unrar on file with all the possible combination. I think I got it to work, but the way it works is it saves the output to a file then compares the outputs. If it was successful, the out put is one size where if it didnt work, the output will be another size. I have the program running until the output is the size of the correct password. I know there must be a better way to go about this. I'm thinking something along the lines of a getline then compare it to what is should be. I was thinking about using

path=c:\Program Files\WinRAR;c:\windows\system32

echo off

set x="y Assume Yes on all queries"

FOR /F "tokens=*" %%R IN ('unrar') DO if echo %%R

yet I cant get it to work. IF someone who has unRAR installed and can help me code this correctly, I am really trying to learn how to code things like this.

Thanks a bunch
