color=#0000ff size=2>BTW I remember Markus showing us a way to save commands you
type to the GRASS CLI into a script (think is was X.save where X=something)..
this is good if you want to perform it once in geenral and then edit the script
for variations. Couldn't find it off hand in the docs.</FONT></SPAN></DIV>

color=#0000ff size=2>I'd be interested to know if you could set and use
variables in the approach we used bellow. I never tried. but if you could
say use output=$OUTMAP and input=$INMAP and then you can loop for a series of
maps. and the input and output are auto generated based on the basefile
name.</FONT></SPAN></DIV>

<DIV>Putting $!/bin/sh at the top of a script will ensure that the file gets
interpreted by whatever the default shell is on the system. Forcing other
shells is also possible here, but using just "sh" means you get the default
(i.e. as opposed to bash, csh, tcsh, ksh, etc etc).</DIV><BR>

<DIV>Note this makes the file readable, writeable and executable to everyone on
the system. If this is just your own private linux or windows box, you
probably don't care, but if someone is doing this on a multi-user system, you
might not want other people to be able to edit your files. Using chmod 755
would make it readable and executable to anyone, but only writeable to you, the
