Homebrew Info, Doctor, and Search
I learned a couple of Homebrew commands today. The first is
brew info, which tells you about your Homebrew installation. Pass it a package name, and Homebrew will tell you about that package.
The next is
brew doctor. This will give you an overview of your Homebrew environment, including unexpected files and symlinks, and whether there is a newer version of Homebrew available than the one you have.
The third is
brew search. Pass this a package name and Homebrew will tell you all the versions that are available.
$ brew search phantomjs homebrew/versions/phantomjs17 homebrew/versions/phantomjs192 homebrew/versions/phantomjs182 homebrew/versions/phantomjs198 Caskroom/cask/phantomjs
You can then
brew install homebrew/versions/phantomjs182 to get the version you need.
