Sharing files but with some prevent of overwriting by my own and others?

I don't want to share one of my files with anyone and I also want to prevent overwriting/modifying the file by my own mistakes (read-only). How should I do that change in the file persmission mode using the chmod utility in octal mode? (Red Hat Linux)

  1. "I don't want to share one of my files with anyone", that's what user accounts are for. Never let anyone login as you.

    "I also want to prevent overwriting/modifying the file by my own mistakes (read-only)." Simple, always modify a COPY of the previous original document. This has nothing to do with permissions.
