===== - Command line =====
==== - Basic command ====

  defaults write com.apple.finder AppleShowAllFiles -string YES

Let’s take it apart to get familiar with the terminology used throughout this article:

  * defaults - interface
  * write - method
  * comapple.finder - domain
  * AppleShowAllFiles - key
  * -string - type descriptor
  * YES - new value

==== - Method ====
  * read - prints current user settings
  * read-type - prints the type of given key
  * write - writes new settings
  * delete - deletes a key or a full domain
  * domains - prints the full list of domains
  * find - searches all domain and keys for a given name
  * help - I’m sure you know what this does

==== - Domains — system components and installed apps ====
Domains are objects that contain settings for a particular system component, installed application or a configuration .plist file located in<color #ed1c24> **/Library/Preferences/**</color>.

  # List all domains
  defaults domains
  defaults domains | tr ',' '\n'
  
===== - Read/Write/Modify a key =====
==== - A basic workflow to amend user defaults ====

  - Print the settings for the notes app to find the right key.
  - Check the value type for a given key.
  - Write new settings.

==== - The way to find the domain & key responsible for a setting ====

  - Save a state before a change.
  - Make a change through GUI.
  - Save a state after a change.
  - Find the difference.

==== - Example: Systempreferences - Shortcuts ====

  # Read global shortcuts
  defaults read -g NSUserKeyEquivalents
  defaults read-type -g NSUserKeyEquivalents
  ## Type is dictionary
  
  # Write global shortcuts
  defaults write -g "NSUserKeyEquivalents" -dict \
