    # I actually use this one:
    # yay -Syyu --noconfirm

    # Remove unneeded dependencies.
    # NOTE: Strangely both [$ yes | yay -Scc] and [$ yay -Scc --noconfirm] will prompt you to remove dependencies so [yay -Ycc --noconfirm] needs to be called first to prevent that prompt from displaying.
    #
    # NOTE: The command [yay -Ycc --noconfirm] is implemented in https://github.com/Jguer/yay/blob/next/cmd.go
    #       It calls cleanDependencies(...) defined in https://github.com/Jguer/yay/blob/next/clean.go
    #       Which calls hangingPackages(...) defined in https://github.com/Jguer/yay/blob/next/query.go
    #
    # WARNING: This version will not work [$ yes | yay -Scc --noconfirm].
    #          The prompt will still be displayed to delete dependencies,
    #          Yay AUR build directory $HOME/.cache/yay/ will be purged,
    #          but no cleaning will take place in Pacman cache directory /var/cache/pacman/pkg/ and Pacman database directory /var/lib/pacman/
    #          because the --noconfirm forces the "yes |" to be ignored, resulting in the default Pacman behavior of not cleaning anything to occur.
