We're trying to change user passwords through a CLI (Command Line Interface) in Plesk - but we're not having any luck. This is Plesk 2.5 (assuming it would be fairly similar on any version). We're also trying to change admin unix user password.

We're thinking that we can change the admin password in mysql and then change /etc/psa/.psa/shadow but i would rather use a cli if there's one available

Does anyone have any concrete code? or a way of doing this?

Thanks for your help.
