brew info mongodb
will display it. If you make the changes suggested by the Caveats however, there may be other Caveats presented which will be more applicable to your actual situation.
I created a brew external command for that: 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
You can also pass multiple formulas:
$ 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
Pretty handy when you need to check some configs!
To see all caveats of the currently installed formulas you can use the following command
brew info $(brew list)
You can also filter the output with awk to only get the caveats sections. (I am an awk newbie suggestions or edits are welcome)
brew info $(brew list) | awk '/^==> Caveats$/,/^[a-z][a-zA-Z0-9_+-]+: stable |^==> (Dependencies|Options)$/'
Another possibility is to use sed
brew info $(brew list) | sed '/==> Caveats/,/==>/!d;//d'
And to have a formatted output (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;
