     QProcess myProcess;
     QString str;

     myProcess.start( "ls" );

     if (!myProcess.waitForFinished())
          qDebug() << "Make failed:" << myProcess.errorString();
          qDebug() << "Make output:" << myProcess.readAll();

          str = myProcess.readAll();
          qDebug() << "string = " << str;

	 QByteArray array = myProcess.readAllStandardOutput();

     	 qDebug() << "array size = " << array.size();


The string = "" and the array size = 0;

This is just a test example. I have a bash script that I want to add to 
my code.
