taskwarrior, delete old recurring tasks

Question

How would I delete all recurring tasks in taskwarrior, which are completed, till some date?

I tried:

task Nevena until:07/29/2014 uuids

to get listed those that fall before that date, and collect their id's, so I could pipe them to delete command, but I did not get expected results.

I believe the answer is to delete the parent tasks and then the recurring tasks will no longer get created. You can show all parent tasks with task all +PARENT. For example:

$ task all +PARENT

ID St UUID     Age  Done Tags R Due        Until Description                                     
21 R  58e83c9b 1.7y           R 2018-04-01       replace upstairs air filter                     
20 R  f8b5b0db 1.7y       [1] R 2018-04-01       replace upstairs air filter

I somehow had two recurring tasks for the same thing. I can delete them:

$ task delete 21 
Delete task 21 'replace upstairs air filter'? (yes/no) yes
Deleting task 21 'replace upstairs air filter'.
Deleted 1 task.
$
$ task delete 20
Delete task 20 'replace upstairs air filter'? (yes/no) yes
Deleting task 20 'replace upstairs air filter'.
Deleted 1 task.

Now the recurring tasks shouldn't show up any longer.
