I wrote the following script a couple of years ago to see how this
could be done (we didn't need to in the end).  I'm sure that it could
be a lot prettier but at least it's a starting point !  To find out what
the variables need to be set to on your system, it's easiest to start
grass and type "printenv |more" (assuming you use csh).

The files:

----------<<  grassrc_test  >>----------
GISDBASE: /data/grass
LOCATION_NAME: tyne
MAPSET: phil


----------<<  exec_grass  >>----------
#!/usr/bin/csh

set path= (/user/grass/sun4/bin /user/grass/sun4/scripts /user/grass/sun4/garden/bin /user/grass/sun4/alpha/bin /usr/local/bin /usr/bin /usr/ucb /etc /usr/etc /usr/lib)
setenv GISBASE /user/grass/sun4
setenv GISDBASE /data/grass
setenv GISRC grassrc_test
setenv LOCATION /data/grass/tyne/phil
setenv LOCATION_NAME tyne
setenv MAPSET phil
