Again, if you are in a directory (in your case /home/ccuser/workspace/movies/drama/historical) you can’t navigate to parent drama by doing cd drama, this would navigate to the directory /home/ccuser/workspace/movies/drama/historical/drama, which doesn’t exist, you need to go to the parent directory. which you can do cd .. to navigate to the parent directory. If you do ls -a you should see a full stop and two full stops:

.
..

these indicate current directory (.) and parent directory (..)
