ls -d parameter in the interpretation

man ls interpreted as the parameter d

-d, --directory
                list directory entries instead of contents, and do not dereference symbolic links

list directory , replacing the contents of this symbolic link are not shielded how to understand it , please explain the great God , the best example , thank you.
------ Solution ---------------------------------------- ----

  $] ls *
  dir1:
  file_in_dir1
  
  dir2:
  file_in_dir2
  $] ls -d *
  dir1  dir2
  $] tree
  .
  ├── dir1
  │   └── file_in_dir1
  └── dir2
      └── file_in_dir2
  
  2 directories, 2 files
  

  $] ls dir*
  dir1:
  file_in_dir1
  
  dir2:
  file_in_dir2
  $] ls dir* -d
  dir1  dir2
  

You can use wildcards to appreciate differences.


If ls followed by a number of parameters , including the directory if not with the-d , it will display the files in that directory with -d time , only the directory name itself
--- --- Solution --------------------------------------------
If ls-ld behind is a directory , then only shows the properties of this directory does not display the directory of the file attributes.
-d parameter to remove it, on the contrary, only shows the properties directory of the file is not displayed in this directory attributes.
------ For reference only -------------------------------------- -
-d list only directories, not including content, not reference symbolic links
actually only lists the current directory
eg: ls-d only .
The ls-d / etc displays / etc
------ For reference only --------------- ------------------------
