unity-control-center is a graphical user interface to
configure various aspects of Unity.
When run without arguments, the shell displays the overview, which
shows all available configuration panels. The overview allows to open
individual panels by clicking on them. It also has a search entry to find
panels by searching keywords.
It is also possible to specify a panel name as commandline
argument to go directly to that panel. Individual panels may accept further
arguments to specify which tab to open (for multi-tabbed panels) or which
item to display (for panels with lists).
Note that unity-control-center is not meant to expose each
and every setting that is available. The settings that can be found here
represent what is considered useful and commonly needed options. For more
exotic or uncommon options, you can look at gnome-tweak-tool or the
gsettings commandline utility.
