macOS applications and other programs use the defaults system to record user preferences and other information to be maintained when the application isn’t running (font for new documents, or the position of an Info panel). Much of this information is accessible through an application’s Preferences panel but sometimes they’re hidden. User defaults belong to domains, which typically correspond to individual applications. 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, it may be specified in NSGlobalDomain.

  read <domain> <key>                  shows defaults for given domain, key

  read-type <domain> <key>             shows the type for the given domain, key

  write <domain> <domain_rep>          writes domain (overwrites existing)
  write <domain> <key> <value>         writes key for domain
