still don’t understand how I was supposed to know to use “cd …” rather than “cd drama/”, this course hasn’t taught “cd …” up to now, and I still don’t understand why that worked

@jaim3m,
If you do a

ls -als

you will see a line with ..
which is a file-system pointer to the Parent directory…

If you then use

cd ..

you will change-directory into this Parent-directory
