Hello,

I assume you have some kind of programing language which executes grass
commands. Can you parse the output? If so then you could do it like this:

g.region rast=raster1
g.region -p (parse the output, into rast1north, rast1east, rast1west,
rast1south, etc)
g.region rast=raster2
g.region -p (parse the output, into rast2north, rast2east, rast2west,
rast2south, etc)
g.region north=(min of rast1north, rast2northe) etc for other parameters.


Hope this helps,
