for cask in $(brew list --cask); do brew upgrade --cask $cask; done;

一个简单的FOR循环迭代所有的桶，而不是手动升级一个接一个。

可以列出已安装的桶:

brew cask list

并强制重新安装桶与:

brew cask install --force CASK_NAME

因此，将第一个命令的输出输出到第二个命令中，我们更新了所有的桶:

brew cask list | xargs brew cask install --force

现在终于有了一个官方的Homebrew Cask升级机制(参见第3396期的实现)!要使用它，只需运行以下命令:

酿造升级——酒桶

但是，这将不会更新没有版本信息的桶(version:latest)或具有内置升级机制的应用程序(auto_updates true)。要重新安装这些桶(并在升级可用时升级它们)，运行带有——greedy标志的upgrade命令，如下所示:

酿造升级—酒桶—贪婪

变得过时:

酿造过时——酒桶——贪婪——冗长

brew cask outdated | xargs brew cask reinstall --force

基于@Atais的回答，我将他的逻辑增强为更好的东西。我想要一种方法，在真正强制升级之前，首先检查要升级的包。

$ brew- bucket .sh只是列出了一个类似Homebrew的酿造更新的输出。 上面的列表显示了所有安装的包，绿色的特遣队表示任何未决的更新。 $ brew- bucket .sh upgrade将强制升级这些包。

代码:

# Usage:
#
#  $ brew update
#    You should execute this first to update everything locally.
#
#  $ brew-cask.sh [update]
#    This will list all of your cask packages and rather there is an upgrade
#    pending with a ✔ checkmark, just like Homebrew does with "brew update".
#    The update command is optional, as it doesn't actually do any tracking, there's
#    not really anything to "update" with cask.  But it keeps with the pattern of
#    of Homebrew's "brew update" pattern for those with memory muscle fingers (like me).
#
#  $ brew-cask.sh upgrade
#    This performs a "brew cask install <cask> --force" of all cask packages that have
#    an update pending.
#
# This code was inspired by http://stackoverflow.com/a/36000907/56693

# get the list of installed casks
casks=( $(brew cask list) )

if [[ "$1" == "upgrade" ]]; then
  for cask in ${casks[@]}; do
    current="$(brew cask info $cask | sed -n '1p' | sed -n 's/^.*: \(.*\)$/\1/p')"
    installed=( $(ls /opt/homebrew-cask/Caskroom/$cask))
    if (! [[ " ${installed[@]} " == *" $current "* ]]); then
      echo "Upgrading $cask to v$current."
      (set -x; brew cask install $cask --force;)
    else
      echo "$cask v$current is up-to-date, skipping."
    fi
  done
else
  echo "Inspecting ${#casks[@]} casks. Use 'brew-cask.sh upgrade' to perform any updates."
  for (( i = i ; i < ${#casks[@]} ; i++ )); do
    current="$(brew cask info ${casks[$i]} | sed -n '1p' | sed -n 's/^.*: \(.*\)$/\1/p')"
    installed=( $(ls /opt/homebrew-cask/Caskroom/${casks[$i]}))
    if (! [[ " ${installed[@]} " == *" $current "* ]]); then
      casks[$i]="${casks[$i]}$(tput sgr0)$(tput setaf 2) ✔$(tput sgr0)"
    fi
  done
  echo " ${casks[@]/%/$'\n'}" | column
fi

只要安装它(也就是“我现在就需要它!”)

它被检入我的。dotfiles回购;所以，你可以快速地将它安装到你的~/binwith:

$ curl -L https://raw.githubusercontent.com/eduncan911/dotfiles/master/bin/brew-cask.sh --create-dirs -o ~/bin/brew-cask.sh
$ chmod 755 ~/bin/brew-cask.sh

然后像这样使用它:

$ brew-cask.sh
$ brew-cask.sh upgrade

如果你的路径中没有~/bin，在上面的语句前加上~/bin/。

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。
