ls command: what does the first line mean?
I have an empty directory.I am using following command to view the contents of that directory.
The output I get is below.
total 12 drwxr-xr-x 5 root root 4096 Oct 2 12:26 .. drwxr-xr-x 2 apx aim 4096 Nov 29 18:40 .
I don't have any files in this directory,then what counts out to 12 here (
total 12 ) ?
