My mistake. It's been a good 30 years or more since I've used tcsh.

setenv takes two arguments, the variable and value. You have three, but
see below.

Indeed. Note that in this Bash version the environment variable is only
set for the program being called, and is then forgotten. If you want it
to persist you need to do 'VAR=value; export VAR'.

Alternatively:

$ env XDG_CURRENT_DESKTOP=GNOME gnome-control-center

which should work independently of what Shell you're using). See
env(1).
