FILE Locking in UNIX
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!
