Cask let’s you install commonly used software, stuff that you would drag and drop to install, via the Terminal or a script. For example,

brew cask install google-chrome

will install Google Chrome. While Homebrew let’s you install command line utilities, Cask let’s you install macOS desktop (GUI) software.

If you’re a developer, you can use cask to install your preferred browsers, code editors, tools and such with a simple script.

• search — searches all known Casks
• info — gets details about a particular Cask
• install — installs the given Cask
• uninstall — uninstalls the given Cask
• brew cask uninstall --force - uninstall all versions of a Cask

Homebrew-Cask is a part of Hombrew version 0.9.5 and higher. It implemented as a subcommand of Homebrew. All Homebrew-Cask commands begin with brew cask

Caskroom is the equivalent of Cellar. It stores all the Casks installed.
