All goods, chattels, moneys, and other property, both real and personal, or any interest therein of the judgment debtor, not exempt by law, and all property and rights of property seized and held under attachment in the action are liable to execution. Shares and interest in any corporation or company, debts and credits, and all other property, both real and personal, or any interest in either real or personal property, and all other property not capable of manual delivery may be attached on execution, in like manner as upon writs of attachment.
