The nice thing about chattr is that you can protect the file's directory entry (which one?) from being deleted. But I agree that using chattr without having first understood chmod is like using a circular saw without having first mastered the screwdriver. Not recommended :-)
It also requires superuser, so it isn't going to help at the user level.There is nothing a user can do to *prevent* himself from destroying his own files, but simply removing write permission from the file & directory will keep it from happening accidentally (he could still put back write permission and delete/modify the file).
