People have already given direct answers, and the indirect answer of ‘set up regular automated backups’ (which everyone should set up right now if they haven’t already), but for the sake of throwing another option out there, people could take a look at ‘trash-cli’: github.com/andreafrancia/trash-cli
(P.S. I know OP might not have actually deleted the files with ‘rm’, but this addresses a broadly similar issue.)
