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/。

这样的剧本是我自己做的。请查看github https://github.com/pesh1983/brew_cask_upgrade。它有很好的描述，但如果你有任何其他问题，请随时问我。它进行了公平的升级:卸载和安装，因此任何必要的清理将由“brew”本身执行。

brew list --cask | xargs brew upgrade

这循环通过所有应用程序安装的酿造桶和升级他们一个在时间。

brew upgrade --cask

对我已经没用了。

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。

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

买过时的酒桶:

酿酒桶过时了

升级桶:

酿造桶重新安装过时的桶

演示脚本:

$ cat ~/bin/brew_cask_upgrade.sh
#!/bin/bash
red=$(tput setaf 1)
# green=$(tput setaf 2)
reset=$(tput sgr0)

(set -x; brew update;)

for cask in $(brew cask outdated | awk '{print $1}')
do
    echo "${red}update ${cask} ...${reset}."
    (set -x; brew cask install --force "$cask";)
done

echo "${red}brew clean up ...${reset}"
(set -x; brew cask cleanup;)
echo "${red}brew clean up done.${reset}"
