Oops,
checking for your reply, I notice an error in my code at line 3 :
replace i=0 with i=$((k-10))
Yours,

Hello Richard,
just a suggestion, though I'm not a bash expert :
k=10
while [ $k -le 250 ]; do
i=0
while [ $i -lt $k ]; do
image=`echo Background_$i.png`
<your stack of operations on $image>;
((i++));
done
k=$((k+10));
done
hmmm, perhaps it's not clean at interval borders, but it may be a good
beginning ?
Good luck,
Vincent.

It's like this. I'm good with Grass-GIS and not good with complicated
scripts.
An r.in.wms process downloaded too many tiles, and broke r.in.gdalwarp.
So, I would like to break up the downloaded tiles into groups of ten,
run r.in.gdalwarp on the groups, then patch the grouped tiles together
at the end.
I have:
Background_ _ <0 to 251>.png
ie -
Background__0.png to Background__251.png
What I want to do is
for i in <group of ten tiles>; do
r.in.gdalwarp input=<grouped filenames> output=<subset> method=nearest
s_srs=EPSG:4326
done
But how do I break the set of 251 tiles into groups for this?
