try this patch:

  sort -n -k2 -t.
(sorts numerically instead of alphabetically, sorts on the second field
[delimited by a "."])

but maybe that hits the max command line buffer of 4096 chars recently
seen in the csh thread??


The typical solution to this problem is to name the files (maps) as
raster.0001, raster.0002, ..., raster.1560.

e.g., to rename maps using awk + printf("%04d"):

#!/bin/sh
for MAP in `g.mlist pattern="raster.*"` ; do
  NEW_NAME=`echo "$MAP" | awk -F. '{printf("%s.%04d", $1, $2)}'`
  #echo "[$MAP] -> [$NEW_NAME]"
  g.rename "$MAP,$NEW_NAME"
done

? No idea. What's the command line you are using? across=1 and down=1?
It writes "$MAPNAME in $MAPSET" text in a caption at the bottom..?


You might also try xganim for the slideshow. (didn't Glynn write a
tcl replacement for this a while back?)

Also r.out.mpeg is there and http://grass.gdf-hannover.de/wiki/Movies
