I don't have your module command currently hence an example with a common 
command:

if you do e.g.

d.rast

the GUI will pop up, if you do 

d.rast --help

you will see syntax

d.rast [-oix] map=string [catlist=cat[-cat][,cat[-cat],...]]
   [vallist=val[-val][,val[-val],...]] [bg=color] [--verbose] [--quiet]

the parts in brackets are optional hence you just have to to enter

d.rast map=your_raster 

to plot the raster.

If you do the same with your command you will get an error message (or not).

You can change the message output with

g.gisenv set=debug=5 (not too sure about that)


hope this helps, cheers, Martin
