Yes, you have a panel without any items in it. A panel in xfce is akin
to the dock on Macs or the Start Bar in Windows.
Right-click on the rectangle and select Panel Preferences. A dialog box
will appear with a menu at the top for selecting all the running panels
(more than one panel can run at the same time). For each panel, you can
adjust the display settings, the appearance, and the items included in
that panel. Note that only one panel can include the notifications area
item. Go to http://xfce.org/ for descriptions of panels and all things
To see the variety of how panels can be used, check out
where I have pics of the two desktops I run. For one desktop, I have
two panels running -- one across the top and a second on the right
bottom corner. On my other desktop, I have just one panel running from
the right bottom corner.
The command you ran to get this info is pretty nifty terminal command
that pipes (the | symbol) one command's output as the input into another
command. In the command you ran, ps is piped into grep which is then
piped into cut. Tomes have been written about ps and grep and probably
cut too, so I'll leave the explanation of these commands to others.
A good way to find basic info about a terminal command is to type the
command followed with --help, such as:
Another option for finding out about a command is to read the man page
(man is short for manual) by typing:
