          Upgrade outdated casks and outdated, unpinned formulae using the same options they were originally
          installed with, plus any appended brew formula options. If <cask> or <formula> are specified,
          upgrade only the given <cask> or <formula> kegs (unless they are pinned; see `pin`, `unpin`).

          Unless `$HOMEBREW_NO_INSTALLED_DEPENDENTS_CHECK` is set, `brew upgrade` or `brew reinstall` will be run for
          outdated dependents and dependents with broken linkage, respectively.

          Unless `$HOMEBREW_NO_INSTALL_CLEANUP` is set, `brew cleanup` will then be run for the
          upgraded formulae or, every 30 days, for all formulae.
