Changing default Dropbox at command line to a business account from a personal account on macOS
Solution 1:
I figured this out. It is possible to point the symlink (purple Dropbox folder) to the business Dropbox folder instead by using this command:
ln -hfs "/Users/username/Dropbox (Business-name)" Dropbox
Now I can simply cd Dropbox which contains the content of my business Dropbox, and a pwd gives /Users/username/Dropbox.
