Unix login session and Password

Hi All,

I've login to Unix using login name guest and I'm working on it,
I need another session to run some script hence tried to login
but password invalid it says here my question is :

Since I'm in working in one session can I set the password without knowing old password? is there any way?

Thanks in advance
Krishna

Hi,

If the policy of that system is that the old password is required to change, you can't do anything as a normal user... If you're super user, you can change that policy.
