Real talk I’ve been using this I’ve mashed together:

update_brew() {
    bold=$(tput bold);
    normal=$(tput sgr0);
    brew --version &&
    echo "${bold} > brew update${normal}" &&
    brew update &&
    echo "${bold} > brew upgrade${normal}" &&
    brew upgrade &&
    echo "${bold} > brew autoremove${normal}" &&
    brew autoremove &&
    echo "${bold} > brew cleanup${normal}" &&
    brew cleanup &&
    echo "${bold} > brew doctor${normal}" &&
    brew doctor;
}
