some shell script loop scripts here: http://grass.osgeo.org/wiki/Movies but none of those really strike me as beginner-friendly. (mea culpa) the general idea is: # set up region g.region rast= # use g.mlist to list all relevant maps g.mlist rast pattern= # eg throw those map names into a loop my @maps = system(g.mlist rast pat=soils.*); my @maps = `g.mlist rast pat=soils.*`; for my $m (@maps) { print $m; `d.erase`; `d.rast $m`; ... `d.out.file $png_name` ... } probably it is good to first run through a loop of all the maps with 'r.info -r' and get the overall range, then create color rules covering that entire range and in a loop apply it to all maps with r.colors. that way the color scale stats the same.
