I just enjoyed reading this long thread. It is good to know other things.

I was editing the file with "notes". I think it is adding empty line. I found that I can as well use vi editor. I did use it and fixed empty line.

I also read in the thread that I get these not found messages since I may not be running all these applications. I am clear now.

Thanks to those who shared.

Only question I have is I have to run 'sudo gainroot' to run the command. If I directly use 'sudo sh otpmize.sh', it is asking password. What is the default password?
