i am trying to understand the concept of the output of ls command, specifically "number of links" for a directory and got utterly confused:
1) when i made first directory in my home directory:
dave@host:~:$ mkdir dir_l1
from the perspective of home directory, the link number for dir_l1show as 2, why 2?
2) then i created second directory inside of the first directory:
from the perspective of home directory, the link number for dir_l1 shows 3, why 3?
from inside of directory dir_l1, the link number for "." is 3, which is the same as its parent directory dir_l1 but ".." also shows 3, why? where did that "total 12" come from?
from the perspective of directory dir_l2, the "." has 2 but ".." has 3, why? where did that 8 coem from?
3) then i created third directory
from the perspective of home directory, the link number for dir_l1 still is 3, why?
from inside of directory dir_l1,
from inside of directory dir_l2:
