### Basic commands `brew help` will show you the list of commands that are available. `brew list` will show you the list of installed packages. You can also append formulae, for example `brew list postgres` will tell you of files installed by postgres (providing it is indeed installed). `brew search <search term>` will list the possible packages that you can install. `brew search post` will return multiple packages that are available to install that have post in their name. `brew info <package name>` will display some basic information about the package in question. ### How do I update my local packages?
