passwd prompts for old password

HP-UX:  Created account with UID 0, tried to change password using passwd.  Passwd prompted for the "old password" even though I was logged in as root.  The man page for passwd explains why:
Superusers are not prompted for old passwords unless they are attempting to change the superuser's password in a trusted system.

job name not known error

In HP-UX when trying to suspend (CTRL-Z) a process/job or when running a job in the background i.e: sleep 30 &   then running the jobs command, if you get message: <job name not known> then you'll need to defined the HISTFILE and HISTSIZE variables to fix the issue.

$ sleep 30 &
[1]     19870

$ jobs
[1] +  Running                    <job name not known>

or suspending the running command with CTRL-Z

$ sleep 20
[1] + Stopped                     <job name not known>

fixed by setting HISTFILE and HISTSIZE:
