It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. See the FAQ for guidance on how to improve it.

The way to do that is to put the file in a directory and revoke the "r" and "x" permissions on the directory from whomever you don't want. There is no standard way to hide a file by just modifying the permissions of the file itself. | |||
