LOCK THAT FILE DOWN

Sometimes you want to make a file very very secure.

To do this, change the permissions to 000

# chmod 000 [file]

No one except root will be able to access it.
Even the owner will have to change the
permissions to be able to do anything to it.

Although It's like a red flag that says..
"I'm an important file"

NOTE: DO NOT EVER DO THIS TO THE /etc/passwd FILE!
