[GRASS-user] Local variables

Just a quick question. Are the parameters of a region available as variables to be called from a shell script or do I need to use g.region to assign them to variables from within the script.

Cheers,

Mike

You need to run g.region to get them.

You need to run g.region, like:

  eval `g.region -g`

That will set the following variables:

  n s w e nsres ewres rows cols
