By the way. Instead of being setting everytime g.region xxxx -p can I
save a region definition
As it says in the g.region manual:
save=name
Save current region settings in named region file
So:
g.region xxxx -p save=<your_region_name>
and use it everytime? If so, how do I load region definition in a script?
Each time you start GRASS it begins with the region settings from the
previous session. You can go to any other saved region by:
g.region region=<your_region_name>
Thanks

The region.
Most raster modules (including r.mapcalc) generate maps with the
bounds and resolution of the current region. Input maps are cropped,
padded and/or resampled to the current region, so all processing
within the module takes place on the grid defined by the current
region.
The main exceptions are the r.in.* modules, which import files
cell-for-cell, using the bounds specified in the file's metadata if
present. The current region is ignored.
Modules which perform their own resampling (e.g. r.resamp.*, r.proj)
create output maps according to the current region but read their
input maps without cropping or resampling.
