Used to access Mac OS X’s user defaults database to read, write (set or change), and delete system and application preferences.

The defaults command allows users and administrators to read, write, and delete Mac OS X user defaults from a command-line shell. An application’s defaults belong to a domain, which typically correspond to individual applications; however, they can apply to system settings made via the System Preferences panels. Each domain has a dictionary of keys and values representing its defaults. Keys are always strings, but values can be complex data structures comprising arrays, dictionaries, strings, and binary data. These data structures are stored as XML property lists.

Though all applications, system services, and other programs have their own domains, they also share a domain named NSGlobalDomain. If a default isn’t specified in the application’s domain but is specified in NSGlobalDomain, the application uses the value in that domain.
