On Linux, when you a create folder, it automatically creates two hard links to the corresponding inode.
One which is the folder you asked to create, the other being the
. special folder this folder.
$ mkdir folder $ ls -li total 0 124596048 drwxr-xr-x 2 fantattitude staff 68 18 oct 16:52 folder $ ls -lai folder total 0 124596048 drwxr-xr-x 2 fantattitude staff 68 18 oct 16:52 . 124593716 drwxr-xr-x 3 fantattitude staff 102 18 oct 16:52 ..

I'm really curious about the whole way these things work so don't refrain from being very verbose on the subject.
EDIT: Maybe I wasn't clear with my post, but I want to understand the underlying mechanism which is responsible for
. files and the reasons why they can't be deleted.
I know the POSIX standard disallows a folder with less than 2 hardlinks, but don't really get why. I want to know if it could be possible to do it anyway.
