After the text that looks like ubuntu@[UNIQUEUSERNAMEHERE]$
sudo vim etc/postgresql/9.3/main/pg_hba.conf
You need to be at root, ie not in some other folder.
cd .. is the command to go up a level in the directory. Go until you cannot go any further up (typing
cd .. until you cannot go any further.)
