Native process execution problem in mac os

Question

hi,
     In my flex application i have to get mac serial  number as a unique id for each system . On searching i got one terminal command to get serial number. For that i have  run terminal command through flex native process. I have set supportedprofile as <supportedProfiles>extendedDesktop desktop</supportedProfiles> in app xml. But when i install and run application on mac terminal is getting opened but command is not executing. I couldn't trace out the problem.  I could execute cmd in windows and that worked . Please help me to findout a solution................... The test code is adding below
private var process:NativeProcess
=
new NativeProcess();
protected function windowedapplication1_creationCompleteHandler(event:FlexEvent):void
                // TODO Auto-generated method stub
                if(NativeProcess.isSupported) {
                    Alert.show("Yes NativeProcess");
                    process.addEventListener(ProgressEvent.STANDARD_OUTPUT_DATA, onOutput);
                    process.addEventListener(ProgressEvent.STANDARD_ERROR_DATA, onIOError);
                    process.addEventListener(IOErrorEvent.STANDARD_OUTPUT_IO_ERROR, onIOError);
                    process.addEventListener(IOErrorEvent.STANDARD_ERROR_IO_ERROR, onIOError);
                    process.addEventListener(NativeProcessExitEvent.EXIT,onIOError);
                    var info:NativeProcessStartupInfo     =     new NativeProcessStartupInfo();
                    info.executable                               =     new File("/Applications/Utilities/Terminal.app/Contents/MacOS/Terminal");
                     /*  var startupArgs:Vector.<String>    =     new Vector.<String>();
                         startupArgs[0]                              =    'system_profiler |grep "r (system)" '; 
                         info.arguments                              =    startupArgs;*/
                    //Alert.show(String(info.arguments.length));
                     process.start(info); 
                    process.standardInput.writeUTFBytes('system_profiler |grep "r (system)" '+ "\n");
                }else
                    Alert.show("No");
            protected function onIOError(event:IOErrorEvent):void
                // TODO Auto-generated method stub
                Alert.show("Error");
            protected function onOutput(event:ProgressEvent):void
                var processID:String            =    process.standardOutput.readMultiByte(process.standardOutput.bytesAvailable,"");       
                Alert.show("Path : " + processID );
I have tried to set arguments but didn't execute......

Hello Aswathy, these days I'm also coding an application which uses AIR NativeProcess and I required to open the MacOS terminal with some parameter/commands. I also eventually turn to the AppleScript, but I considerably new to the AppleScript, yet trying to findout a way to passing parameters (the command argument) to the AppleScript; the appleScript I managed to open but not passing the argument. Can you please help? here's my some probable codes for the application:
My appleScript is:
#!/bin/bash
on run argv
          tell application "Terminal"
                    set currentTab to (do script) & item 1 of argv
          end tell
end run
I've packaged the appleScript as an Application (Contract.app) and here's my Flex code:
var npInfo : NativeProcessStartupInfo = new NativeProcessStartupInfo();
npInfo.executable = new File( "/Applications/Contract.app/Contents/MacOS/applet" );
                              var arg:Vector.<String> = new Vector.<String>;
                                  arg[0]="ssh [email protected]";
                              npInfo.arguments = arg;
                              process = new NativeProcess();
  process.start( npInfo );
Can you please help?
Thank you.
