It's an external command for Homebrew. It provides installation caveat descriptions for Homebrew packages and casks.
Although the script's names is brew-caveats.rb, Homebrew external
commands work in such a way that you invoke them as brew caveats. (It
functions exactly like a sub-command built into Homebrew.)
If you already know the name of a package, and you want to see a bit about it, that's easy:
$ brew caveats zsh redis mysql
==> 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
==> redis: Caveats
To have launchd start redis now and restart at login:
brew services start redis
Or, if you don't want/need a background service you can just run:
redis-server /usr/local/etc/redis.conf
==> mysql: Caveats
We've installed your MySQL database without a root password. To secure it run:
mysql_secure_installation
To connect run:
mysql -uroot
To have launchd start mysql now and restart at login:
brew services start mysql
Or, if you don't want/need a background service you can just run:
mysql.server start
This is also valid for casks:
$ brew caveats osxfuse anaconda
==> osxfuse: Caveats
To install and/or use osxfuse you may need to enable their kernel extension in
System Preferences → Security & Privacy → General
For more information refer to vendor documentation or the Apple Technical Note:
https://developer.apple.com/library/content/technotes/tn2459/_index.html
You must reboot for the installation of osxfuse to take effect.
==> anaconda: Caveats
To use anaconda, you may need to add the /usr/local/anaconda3/bin directory to your PATH environment variable, eg (for bash shell):
export PATH=/usr/local/anaconda3/bin:"$PATH"
Cask anaconda installs files under /usr/local. The presence of such files can cause warnings when running "brew doctor", which is considered to be a bug in Homebrew Cask.
You can install brew caveats in two ways.
- Tap this repository and install via
brewitself. - Install manually.
For the first method, do the following:
brew tap rafaelgarrido/homebrew-caveats && brew install brew-caveats
For the second method clone or download this repository. Then simply put the file cmd/brew-caveats.rb anywhere in your $PATH. For example:
mv cmd/*-caveats.rb ~/bin
Leave the name as is if you follow this method. Homebrew knows how to find it.
Once you've installed via either method, you can use the commands as described above.
