First use pwd to find out where you are.
if you are not "under" or "within" the drama directory, you can write a command to take you there.
$ cd /home/ccuser/workspace/movies/drama
then I did ls to list the files is the directory that I am currently in. (the directory was drama)
when I executed the command ls, it output these 2 files: biopic historical
so I then knew I could work with these files.
i found that if a command in code academy doesn't work, i do pwd (print working directory) to figure out what directory i am actually in, then i can navigate elsewhere if needed.
