Sort of noobish #question that has never really hit me before: how do you change your icon / widget theme from the command-line?

Usually I just copy the theme files to ~/ and choose the theme with lxappearance, but it seems that package isn't included in #AlpineLinux 3.18 (it is in testing). Huh.

Guess it's not a very magical thing in the end? But all answers I find searching around are specific to Ubuntu.
