title: -bash: cd: app: No such file or directory
body: <p>I simply changed the name in finder and now when I use a command in terminal, this is the error I keep receiving. I've tried to look at all the other cases of the same error but they all pertain to different solutions that don't work. The path is clearly correct because when I try to cd into the directory, I'm already in the directory it is contained in.</p>
