[GRASS-user] d.polar strange behavior when using MASK

Hi Markus,
sorry I didn't notice your message before.

The complete output is:

[Raster MASK present]
GRASS 6.2.1 (donetta):~ > d.polar map=aspect.5m at PERMANENT undef=0 
eps=built.eps+ '[' -z /usr/lib/grass ']'
+ '[' map=aspect.5m at PERMANENT '!=' @ARGS_PARSED@ ']'
+ exec g.parser /usr/lib/grass/scripts/d.polar map=aspect.5m at PERMANENT 
undef=0 eps=built.eps
+ '[' -z /usr/lib/grass ']'
+ '[' @ARGS_PARSED@ '!=' @ARGS_PARSED@ ']'
++ basename /usr/lib/grass/scripts/d.polar

++ which awk

+ grep -v '^*$'
+ grep -v '^0$'
+ awk '{printf "%d\n", int($1 + .5)}'
+ sed 's+^360+0+g'

... and it hangs at this point.

Best,
Stefano
