In grass 6.4:
GRASS_OVERWRITE=1
r.mapcalc "result = rand(1,100)"
100%
r.mapcalc "result = rand(1,200)"
##ok, raster result has been overwritten
100%
In grass7.0:
GRASS_OVERWRITE=1
r.mapcalc "result = rand(1,100)"
100%
r.mapcalc "result = rand(1,200)"
### raster 'result' hasn't been overwritten
I have to setting GRASS_OVERWRITE variable and r.mapcalc command in
the same line as you suggest:
GRASS_OVERWRITE=1 r.mapcalc "r = rand(12,24)"
in this case it works in both version. Strange behaviour IMHO.

thanks to all
