At present, there isn't a mechanism to "remote control" the GUI from
the command line.

from the msys-commandline (nc-sample-data):

    GRASS 6.4> d.rast map=myelevation
PNG: GRASS_TRUECOLOR status: FALSE
PNG: collecting to file: map.png,
GRASS_WIDTH=640, GRASS_HEIGHT=480
100%
FEHLER: PNG: couldn't open output file map.png

make sure you have write-permissions in the current directory.

e.g. if you are blocked from writing to C:\ as the non-administrator, then
writing to C:\map.png will fail. But if you cd to your user Desktop dir
for example, it should then work. ?

or perhaps it is some other bug, but the above is worth testing first.

fwiw I removed the path from the GRASS> prompt on wingrass as it gets very
long there, and the DOS box is mostly locked at 80 columns wide AFAICT.
Hopefully the pwd problem does not pop up everyday & we can leave it simple.
(I'd argue that running d.* commands from the command line is advanced usage
for WinGRASS)
