[xubuntu-users] Adding items to a panel with a bash script

[Charles M]

What is the simplest way to add a new item to a panel from the command line?

I see that ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-panel.xml
holds information about what's on the panel, but I'm not exactly sure
how I would add something like the pulseaudio plugin for example.

I found xfconf-query and it appears to be able to do things with
xfce4-panel, just again not sure how I could add something like the
pulseaudio plugin via it.

Thanks,

Charles
