HI!
I am trying to display the tif file ,

by first importing the tif file by
r.in.gdal -e in=nf42_geo.tif out=tm
WARNING: Datum 'unknown' not recognised by GRASS and no parameters found.
         Datum transformation will not be possible using this projection
         information.
Projection of input dataset and current location appear to match.
Proceeding with import...
100%
CREATING SUPPORT FILES FOR tm.red
SETTING GREY COLOR TABLE FOR tm.red (8bit, full range)
100%
CREATING SUPPORT FILES FOR tm.green
SETTING GREY COLOR TABLE FOR tm.green (8bit, full range)
100%
CREATING SUPPORT FILES FOR tm.blue
SETTING GREY COLOR TABLE FOR tm.blue (8bit, full range)
r.in.gdal complete.

now i am trying to display the imported file..
i got the error

g.region rast=tm
ERROR: raster map <tm> not found.

GDAL imports multband files (including multiband tifs) by creating a raster map/image for each band. GRASS does not store files in a multiband format. It also imports RGB files in the same way, splitting them into their red, green, and blue components. You can display them as an RGB color-fused image by using d.rgb (not the brightness setting too) or by recombining them into a single RGB using r.composite.

when i observe three files are created in PERMANENT/cats
tm.red,tm.blue,tm.green.
but it is not the actual file that i want to see..
Please tell how could i display it.
Thanks in Advance
