brew missing                 # list missing dependencies
du -sh $(brew --cache)       # check cache size

Pattern Comuni

Flussi di Lavoro Quotidiani

Aggiornamento mattutino	`brew update && brew upgrade && brew cleanup`
Configurazione nuovo Mac	`brew bundle install` da un Brewfile
Esporta configurazione	`brew bundle dump --file=~/Brewfile`
Controlla salute	`brew doctor`
