Well, these is a solution for that also.

The list of directories will be shown with contents inside it. Let’s see an example for it.-
Now suppose, you don’t want to get the content inside the directory but you want to get the get list of directories with it’s sub directories-
You will have to run ls * command to get the list of directories and sub directories.
