The _get command is a DOM
accessor. You can use this command to extract any piece of information
stored by taskwarrior. For example to obtain the description of task 12:
$ task _get 12.description Buy some milk
You can specify multiple data items:
$ task _get 12.description 12.project Buy some milk Kitchen
You can use UUIDs:
$ task _get a360fc44-315c-4366-b70c-ea7e7520b749.description Buy some milk
The _get command makes it easy to map between ID and UUID:
$ task _get 12.uuid a360fc44-315c-4366-b70c-ea7e7520b749 $ task _get a360fc44-315c-4366-b70c-ea7e7520b749.id 12
The _get command is a helper command, which means it
is more useful for scripts and extensions than command line use.
