Terminal and Scripting
Use Default Commands to Modify App Behavior

This can range from simple operations like opening or closing apps to more complex tasks like adjusting app settings or automating tasks.
- Examples: Common commands include open to launch applications, defaults to change app preferences, and scripts for automating routine tasks. For instance, using defaults write followed by an app’s domain and a preference key, you can modify specific behaviors of an app.
