>You'll be better off using a foreach command, for example:

here is a minimal beginning:

#!/bin/sh
files=`g.list t=rast m=PERMANENT | egrep -v '^----' | egrep -v '^raster files'`
for i in $files; do
  echo processing $i
done

see the programming manual (chapter 25) and $GISBASE/scripts
for hints.

BTW, it sure would be a nice addition to the g.list command
if we could have a flag that would rid us of the extraneous
information that I had to grep out... or have I missed something.
