WAT

• To set default application: ./its-mine set-default <bundleIdentifier> <UTI>
• To set default applications from a JSON file: ./its-mine set-defaults-json <jsonFilePath>
• To find UTI for a file extension: ./its-mine find-uti <fileExtension>
• To find app bundle identifier: ./its-mine find-app <appName>

Some example runs:

./its-mine find-app /Applications/Sublime\ Text.app
Bundle Identifier: com.sublimetext.4
App Path: /Applications/Sublime Text.app

./its-mine find-uti "csv"
UTI for file extension 'csv': public.comma-separated-values-text

 ./its-mine set-default com.sublimetext.4 public.comma-separated-values-text
 Default application set successfully

Something something "set default applications from a JSON file"

/path/to/your/mappings.json

[
  { "bundleId": "com.sublimetext.4", "uti": "public.comma-separated-values-text" }
]
