... or you can make the file immutable with chattr(1) (if your file
system is ext2/ext3):

    sudo chattr +i file

... and use lsattr(1) to look at the extended attributes.

Making a file immutable has some side effects though (from "man
chattr"):

    A file with the `i' attribute cannot be modified: it cannot be
    deleted or renamed, no link can be created to this file and no
    data can be written to the file.  Only the superuser or a process
    possessing the CAP_LINUX_IMMUTABLE capability can set or clear
    this attribute.

But, if it is what you want, use it!

Note: other file systems may have other properties.
