Starting GRASS

• See the grass6 and helptext help pages.
• http://grass.osgeo.org/gdp/grass5tutor/HTML_en/c626.html contains advice on setting up a directory structure for GRASS projects.

It advises:

 /data/            # as a shared directory for team projects with sysop managed group permissions
                   # this shared directory may stay on a network server
 /data/grassdata   # GRASS GIS database 
 /data/grassdata/spearfish60    # a shared spearfish Location (think project)
 /data/grassdata/spearfish60/maria    #  a team member's working mapset
 /data/grassdata/spearfish60/david    # another member's working mapset

For individual use, such a structure is not necessary. One will need a database, and GRASS can create Location and Mapset directories. Your default database/location/mapset may be stored in your .grass6rc file.

GRASS can be invoked with:

grass64 --help  # print options
grass64   # start with defaults from .grassrc6
grass64 /data/grassdata/spearfish/david  # a specific mapset
