list files command output

Hi All,

Below is the 2 different ouputs of the command "ls -lrt", my question is what exactly "total 0" & "total 8" means here ?

$ ls -rtl
total 0
-rw-r--r--    1 oracle   dba               0 Feb 10 20:16 c
-rw-r--r--    1 oracle   dba               0 Feb 10 20:16 b
-rw-r--r--    1 oracle   dba               0 Feb 10 20:16 a
drwxr-xr-x    2 oracle   dba             256 Feb 10 20:16 new

 
$ ls -rtl
total 8
-rw-r--r--    1 oracle   dba              11 Feb 10 20:16 a

Kamal
