you need an echo:

  GRASS> echo "natemp20092010=mynatempnewrast + 0" | r.mapcalc

less awkward would be:

  GRASS> r.mapcalc "natemp20092010 = mynatempnewrast + 0"

(although I'm not really sure what the point of the +0 is)


in GRASS 7 you'll need a space around the "=", may as well get
in the habit of doing that now.
