Primeiramente olá, meu nome é Matheus Ferreira, analista de sistemas, especialista em GNU/Linux. Criei este script para meu uso e resolvi postar aqui no VOL.

O script executa a atualização do sistema, exclusão de pacotes antigos e que não estão sendo mais utilizados, e ao final limpa a memória cache e swap, por isso dei o nome para ele de Otimizador. Uso ele constantemente para deixar meu sistema atualizado e memórias limpas. Aproveitem!
