Struggling with rt-shredder CLI syntax

Can someone tell the syntax to schred all the tickets for a particular
year that have been resolved.

i found this example in an email

rt-shredder --plugin “Tickets=query,((status = ‘resolved’) AND

it found some, but when i go back to the web interface and look there
are still some there.

i am not sure what i am doing wrong and the doc is not completely helping

thanks for any insight
