I only learned what pacman -Syu meant, after literal years of typing it in not knowing anything other than “this updates the packages”, because I got curious and googled it.

To me it was just an adeptus mechanicus incantation.

EDIT: And I still have no clue how ‘y’ translates to ‘refresh the database’. Like. Sure. S to synchronise from the server to the computer. And u to mark for update all the updatable packages. But – Why the fuck is ‘y’ the refresh?
