I have 41 webform password items stored in Keychain. Each item has the same password (since each of them is a different wifi router in our building).
Every few months, I need to update all of these items to reflect the new password set up our sys admin. Is there a quick terminal script that I can use to batch update the password of any item whose name contains "10.18.124." from "oldpw" to "newpw"?
