Spearfish data set installation:

If you don't have, create a directory "grassdata" (or similar) in your home directory or use an existing directory
change into that directory (cd grassdata)
extract the data set here (<data set> may be "spearfish"):

GRASS 6.0 LOCATION: This is the name of an available geographic location. -spearfish- is the sample data base for which all tutorials are written. MAPSET: Every GRASS session runs under the name of a MAPSET. Associated with each MAPSET is a rectangular COORDINATE REGION and a list of any new maps created. DATABASE: This is the unix directory containing the geographic databases The REGION defaults to the entire area of the chosen LOCATION. You may change it later with the command: g.region - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - LOCATION: spearfish60___ (enter list for a list of locations) MAPSET: user1_____ (or mapsets within a location) DATABASE: /opt/grassdata____________ AFTER COMPLETING ALL ANSWERS, HIT <ESC><ENTER>TO CONTINUE (OR <CTRL><C> TO CANCEL)

the location name is the name of the data set subdirectory (e.g. spearfish60 or imagery60)
the mapset name is users1 (at your choice)
leave this screen with <ESC><ENTER>

Now you can "play around" with GRASS!
