My hot tip: initial capital so that your aliases are just a capital letter + tab away. Cache cleanup, update and Bleachbit:
alias Päivi='sudo pacman -Suy --noconfirm'
alias Siivous='sudo pacman -Sc --noconfirm;sudo pacman -Rns --noconfirm $(sudo pacman -Qtdq)'
alias SuurSiivous='sudo bleachbit -c system.trash system.ro tated_logs system.localizations java.cache journald.clean b ash.history'
Now is proper.
