l -- For long listing example as below
t -- for latest time stamp -- After you make the changes
etc.
d -- stands for the information about the current directory
as shown below

Ex o/p as below :

drwxrwxr-x 3 oi oi 1276 Mar 25 11:47 .

3 above stands for no. of directories in the current
directory minus 2 , This means above directory has one
child directory


when o/p shows as below :

ls -ltd
drwxrwxr-x 5 oi oi 1399 Mar 25 11:55 .

This would mean parent directory has 3 child directories
(i.e 5-2 = 3 child directories)

Why minus 2 -- Current directory has 2 links so the same
number need to be deducted from the total number
