      System.err.println("Usage: java BigFile sizeInMegs FileName");
      return;
    }
    byte[] meg = new byte[1024*1024];
    int sizeInMegs = Integer.parseInt(args[0]);
      long sk = sizeInMegs;
      sk = sk * meg.length;
    System.out.println("Creating "+args[1]+" of "+(sk+args[0].length()+1)+" bytes called bigfile.tst");
    try {
      RandomAccessFile raf = new RandomAccessFile(args[1], "rw");
      raf.seek(sk);
      raf.writeBytes(args[0]+"\n");
    raf.close();
    }catch(Exception e){
