Question

在安装自制软件时，您偶尔会在“警告”部分获得一些有用的信息，您可能希望将它们放在帽子下面。有没有什么方法可以在安装时显示重播或访问此信息，或者除非您在某处复制粘贴，否则它会永远丢失？

e.g。

==> Caveats
To have launchd start mongodb at login:
    ln -s /usr/local/opt/mongodb/*.plist ~/Library/LaunchAgents/
Then to load mongodb now:
    launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
Or, if you don't want/need launchctl, you can just run:
    mongod

我可能希望能够再次看到这个并且/或者知道如果我以后想要它的位置。

tl; dr 在我安装自制软件后，如何再次看到上述代码？

Answer 1

brew info mongodb会显示它。但是，如果您进行了警告建议的更改，则可能会出现其他更适用于您实际情况的注意事项。

Answer 2

我为此创建了一个brew外部命令：https://github.com/rafaelgarrido/homebrew-caveats

$ brew caveats zsh
==> zsh: Caveats
Add the following to your zshrc to access the online help:
    unalias run-help
    autoload run-help
    HELPDIR=/usr/local/share/zsh/helpfiles

您还可以传递多个公式：

$ brew caveats rabbitmq mongodb
==> rabbitmq: Caveats
Management Plugin enabled by default at http://localhost:15672

Bash completion has been installed to:
  /usr/local/etc/bash_completion.d

To have launchd start rabbitmq at login:
  ln -sfv /usr/local/opt/rabbitmq/*.plist ~/Library/LaunchAgents
Then to load rabbitmq now:
  launchctl load ~/Library/LaunchAgents/homebrew.mxcl.rabbitmq.plist
Or, if you don't want/need launchctl, you can just run:
  rabbitmq-server

==> mongodb: Caveats
To have launchd start mongodb at login:
  ln -sfv /usr/local/opt/mongodb/*.plist ~/Library/LaunchAgents
Then to load mongodb now:
  launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
Or, if you don't want/need launchctl, you can just run:
  mongod --config /usr/local/etc/mongod.conf

当你需要检查一些配置时非常方便！

Answer 3

要查看当前安装的公式的所有警告，您可以使用以下命令

brew info $(brew list)

您也可以使用awk过滤输出，只获取警告部分。（我是一个awk新手建议或编辑是受欢迎的）

brew info $(brew list) | awk '/^==> Caveats$/,/^[a-z][a-zA-Z0-9_+-]+: stable |^==> (Dependencies|Options)$/'

Answer 4

另一种可能性是使用sed

brew info $(brew list) | sed '/==> Caveats/,/==>/!d;//d'

有格式化输出（bash）

for cmd in $(brew list); do 
  if brew info $cmd | grep -q Caveats; then
    echo "$cmd\n"; 
    brew info $cmd | sed '/==> Caveats/,/==>/!d;//d'; 
    printf '%40s\n' | tr ' ' -; 
  fi; 
done;

Answer 5

对于那些拥有出色的jq工具的人：

# For brews
$ brew info --json $(brew list) | jq -r '.[] | select(.caveats != null) | "\n\nName: \(.name)\nCaveats: \(.caveats)"'

# For casks
$ brew cask --json=v1 info $(brew cask list) | jq -r '.[] | select(.caveats != null) | "\n\nName: \(.name)\nCaveats: \(.caveats)"'

jq是一个命令行JSON处理器。

Answer 6

更新和组合上面的几个答案，这是一个 bash/zsh 循环，可以粘贴到终端中以获取所有已安装 brew 公式的所有警告。

for x in $(brew list --formula); do 
    cavs=$(brew info "$x" | sed '/==> Caveats/,/==>/!d;//d')
    if [ ! -z "$cavs" ]; then
        echo "$x"
        echo "---"
        echo "$cavs"
        echo ""
    fi
done
