[GRASS-user] Beginner (Mac): How do I display a raster in Map Display window using line commands

I'm a complete beginner using GRASS 6.4.0 on a PowerPC Mac (OS 10.4.11).

I using the "North Carolina" sample data.

I am able to run line commands in the Output-GIS.m window (lists, info, etc.), but I am not able to use line commands to display graphical items in the Map Display window. For example, if I run "d.rast Slope", the command apparently is understood, but the Map Display remains blank.

Here is the Output-GIS.m log:

------

PNG: GRASS_TRUECOLOR status: TRUE

PNG: collecting to file: /Users/my_home_directory/grass/nc_spm_08/user1/.tmp/G5.local/891.0.ppm,
     GRASS_WIDTH=690, GRASS_HEIGHT=486

------

Is there some special command I need to add to "target" the Map Display window? Do I have to set up a special directory first?

(Note: I am able to display rasters using the GIS Manager (GUI) window, so I know Map Display works, but I have to learn how to use line commands to accomplish the same tasks.)

Thanks!
