Subject: non-interactive r.mask (v. 4.2.1)
Hi GRASSers,
I have to do some stupid work - so I would rather enjoy to write a skript,
fire it and have a decent cup of tea 
But, unfortunatly, I don´t know
the
right, best, or "state-of-the-art" way.
My problem:
I have many raster data sets which have to be processed in the same way.
That would not be too complicated if I do not have to change between
different MASKs. A possibility would be to write the skript without
automating the MASK setting. Then I would have to
- set MASK no. 1
- fire the skript
- set MASK no. 2
- fire the skript
and so on.
The problem is that r.mask in _always_ interactive. Just to make it short:
Is there a way to set the MASK non-interactivly?
I tried to look at the different MASK file in the $LOCATION directory, and
it looked somehow promising - but it looked aswell to be a lousy hack...
Any suggestions...
With kind regards,
Stephan

If you have several work regions defined within a single raster layer,
it is easy to use a "do" or "for" loop with r.reclass:
(this is in Bourne shell)
----
count=1
while [ $count -le 30 ]
do
r.reclass in=inputmapname out=MASK << EOF
$count = 1
EOF
count=`expr $count + 1`
done
----
