How to delete messages from .maildir/new/ with custom subject?

I have new messages in my .maildir/new/. There are a lot of bug reports I would like to remove.

I would like to remove messages with subject that contains Webkit. How can I do it?

Thanks for any help.

Solution

Each email is simply a file. Removing the file deletes the email.

grep -l -r Webkit .maildir/new | xargs rm
