Ok sure thanks i will check Ritesh Kumar Nayak

Please correct me if my understanding is wrong.

I Mean even though if user wants to have full access it should be 700 not 600 read-4,write-2,execute-1 total 7 and group and others 0 so it would be 700 Ritesh Kumar Nayak

Is that chmod 600 correct code for read,write,execute permission, Please check once.
