nohup and GRASS

Greetings,

I would like to run processes that are not killed when I logout. I have
tried using the nohup command outside of GRASS and receive the following
error message:

ERROR: GISRC - variable not set

My .grassrc file contains:

GIS: /local/grass
GISDBASE: /wma5/peterp/grass
LOCATION_NAME: lahonda
MAPSET: peterp
DIGITIZER: none

My question is what other variable do I need to set in this file? Is
this not the correct file to update

Thanks in advance...
