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>

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>
