Make your files immutable in linux
Posted on November 25th, 2005 by darkmoon
If you are running the ext2 or ext3 filesystem, you can protect files that even root can’t delete with the chattr command. If you add the +i flag to the file, you will make it immutable, which basically makes it so that no one can delete the file.
See how to do it here.
