ls -d showing dot(.) as output why?
 
hi all
when i Giving command ls -d , it displaying dot only but according to concept it should be show the list f directory why?

no
actually ls -d works exactly as expected.
when you give no argument to ls it will take . (current directory) by default. -d means list directory itself instead of its content (see man page)

According to manual
Code:
-d, --directory
              list directory entries instead of contents, and do not dereference symbolic links
Just like if you use
Code:
ls -ld
It shows the details of current directory.
If you want to see the list of sub-directories only (not the sub of sub-directories, only sub-directories), use this.
Code:
ls -l | grep "^d"
If you want to print name of sub directories only,
Code:
ls -l | grep "^d" | awk '{print $NF}'

ls -d shows details of folder itself, not contents of folder.

For ex:
Code:
$ ls -l /media
total 53716
