hp_sum cli with linux for PSP (LSP) deployments

[pakm11]

Using hpsum 4.1.0.

When using hpsum in non-GUI mode, is it possible to specify a null password on the command line and have it prompt for it?
Could not figure this out from reading the user guide.

Other question is managing hosts and host groups.
Is it possible to create and/or manage these using the non-GUI tools?
I want to be able to manage groups by editing files where they are stored, if possible.
It would be nice to convert a text file list of hosts in to groups without having to go through the GUI.


Thanks
