The prompts are asking me to change the directory $ cd and then to type $cd jan/memory/ and then to type $cd.. and print the working directory. It sounds clear to me but it isn't working.
Okay...so I figured it out!!! It was my spacing! I wrote cd.. and I needed a space after cd ..
thanks a lot. I have been stuck 45 minutes on this line without any clue.
I was getting mad.
