The command "brew info --cask ${cask_name}" is used to retrieve information about a specific cask (an application) installed via Homebrew, a package manager for macOS.

Here's a breakdown of the command:

• "brew info" is the basic Homebrew command used to display information about a package or formula. It provides details such as the version, homepage, dependencies, and installation options.
• "--cask" is an option that specifies that the package being queried is a cask, which is a special kind of Homebrew package used for GUI applications.
• "${cask_name}" is a placeholder representing the name of the cask you want to gather information about. It is expected to be a variable that contains the actual cask name you want to query.

By running this command with a specific cask name in place of "${cask_name}", you can obtain detailed information about that particular cask, including its version, homepage, and other relevant details.
