I am needing a command line version of r.mask.

Does such a beast exist. Any help would be appreciated.

Thanks

Steffen,
  The big secret to r.mask is that it creates a new map from
an existing one called: MASK . You can create a mask from any map
by simply using g.copy rast="yourmap",MASK . The mask created will
include all areas with a category value in "yourmap", so a reclass
may be needed to specify specific locations prior to copying "yourmap".

Hope this works for you,
