我已经使用Homebrew有一段时间了(现在是2022年)，下面是我最喜欢的一行命令，每天在我煮早上的咖啡时运行一次。如果您将所有或大部分应用程序作为桶，并由Homebrew管理，并且出于新功能和安全原因希望进行最新更新，那么这是非常好的。

警告:

DO NOT use in a work environment where reliability and stability is key. Although having constantly the latest security updates sounds like a good idea, what is not a good idea is getting updates as soon as they come out. If you are a software developer, modify this command and remove brew upgrade --greedy. This is because it is always better to inspect the versions of the formulae/casks that are outdated before updating for compatibility with your development environments. You are better off upgrading manually the specific formulae/casks that you are sure will not interfere with your projects, and usually that requires inspecting release notes. When separately updating casks/formulae, use brew upgrade cask_name_here.

下面是命令:brew update && brew obsolete -greedy && brew upgrade -greedy && brew cleanup

让我们来解释一下这是做什么的。

brew update命令用于在执行其他操作之前更新Homebrew本身。

brew outdated——greedy命令用于列出所有更新可用的酒桶/公式。贪心参数指定自动更新自己的应用程序和标记为version:latest的应用程序应该包含在这个列表中。

The brew upgrade --greedy command is used to update all casks/formulae which were previously listed as outdated. The greedy parameter specifies that apps that auto update themselves and one's flagged with the version:latest should be included in this update process. Be aware that if you see no output in the terminal after running this command it means that there is nothing to update, unlike the brew outdated command this one does not send a message back to the terminal informing users that nothing needs updating.

brew cleanup命令删除所有公式和桶的旧锁文件和过时下载，并删除已安装公式的旧版本。简单地说，就是这些桶/公式以前版本的旧文件或剩余文件。

开发人员和工作环境的潜在解决方案 如果你想使用如上所述的这个解决方案，并且在Homebrew中有关键的依赖关系，有一个解决方案:

brew pin [package_name_here]

当所有包都用上面的命令更新时，pin命令将停止Homebrew更新指定的包。有关更多信息，这里是将该功能添加到Homebrew的pull请求。

这真的让我很恼火，所以我创建了这个脚本来更新所有的Brew应用程序，并允许用户选择更新哪个Cask应用程序。你也可以将应用程序排除在外。

https://github.com/derrekyoung/ScriptsAndUtils/blob/master/brew-cask-upgrade.sh

根据我所读到的内容，我创建了一个脚本，将创建一个文件，列出要更新的文件，包括定义为最新的应用程序。然后，您可以修改该文件以满足您的需求，并使用我的olinst脚本安装更新。

我和鱼壳打交道。 所以我使用:brew upgrade (brew list—cask)。 这对我很管用。

截至2017年12月使用: 酿造桶升级

[自2017年12月Homebrew为桶引入升级命令以来已弃用] 我简单地使用以下方法:

brew cask outdated | xargs brew cask reinstall

Bash脚本升级包

受到帕斯卡答案的启发

#!/usr/bin/env bash

(set -x; brew update;)

(set -x; brew cleanup;)
(set -x; brew cask cleanup;)

red=`tput setaf 1`
green=`tput setaf 2`
reset=`tput sgr0`

casks=( $(brew cask list) )

for cask in ${casks[@]}
do
    version=$(brew cask info $cask | sed -n "s/$cask:\ \(.*\)/\1/p")
    installed=$(find "/usr/local/Caskroom/$cask" -type d -maxdepth 1 -maxdepth 1 -name "$version")

    if [[ -z $installed ]]; then
        echo "${red}${cask}${reset} requires ${red}update${reset}."
        (set -x; brew cask uninstall $cask --force;)
        (set -x; brew cask install $cask --force;)
    else
        echo "${red}${cask}${reset} is ${green}up-to-date${reset}."
    fi
done

它的作用

更新酿造/酿造桶，清理 读酒桶清单 检查酿造桶信息的最新版本 如果可用，请安装新版本(并删除所有旧版本!)

对不耐烦的人说一句:

curl -s https://gist.githubusercontent.com/atais/9c72e469b1cbec35c7c430ce03de2a6b/raw/36808a0544628398f26b48f7a3c7b309872ca2c6/cask_upgrade.sh | bash /dev/stdin

保存为/usr/local/bin/桶-upgrade，以便稍后在本地以桶-upgrade的形式运行
