Answer 1

I use brew [cask] cat [...] to see the exact formula (without necessarily editing it as other answers here suggest). It shows what gets downloaded, from where, with what checksum, what other formuli/casks it depends on, etc. Here's an example:

$ brew cask cat java
cask 'java' do
  version '12.0.2,10:e482c34c86bd4bf8b56c0b35558996b9'
  sha256 '675a739ab89b28a8db89510f87cb2ec3206ec6662fb4b4996264c16c72cdd2a1'

  url "https://download.java.net/java/GA/jdk#{version.before_comma}/#{version.after_colon}/#{version.after_comma.before_colon}/GPL/openjdk-#{version.before_comma}_osx-x64_bin.tar.gz"
  name 'OpenJDK Java Development Kit'
  homepage 'https://openjdk.java.net/'

  artifact "jdk-#{version.before_comma}.jdk", target: "/Library/Java/JavaVirtualMachines/openjdk-#{version.before_comma}.jdk"

  uninstall rmdir: '/Library/Java/JavaVirtualMachines'
end

Answer 2

In homebrew you have casks and formulas, which have different functions, so:

For formulas:

To get info about the formula itself you can use what you did (brew info [formula name). To get info about the app you're installing use:

brew desc [Formula name]

You can also go to the homebrew's site for the formula via brew home [formula name

For Casks:

Sadly, casks (like Firefox) don't have the desc command and you only have brew cask info (what you used) and brew cask home

Answer 3

Nope. Homebrew intentionally lets the web sites serve as documentation of the packages, instead of maintaining a separate copy of it.

You can do a brew home <formula> to fire up a browser from the command line, or brew edit <formula> to examine the formula's installation instructions themselves in an editor.

Answer 4

You can get a one-line textual description of a package with:

brew desc FORMULA-NAME

For example, "brew desc terminator" returns:

terminator: Multiple terminals in one window

Answer 5

try this:

brew cask info [package]
