At times it would be nice to be able to make a file containing a set of
GRASS commands, then submit it to be executed at a particular time using
the unix "at" command or "crontab" Although I can make a file of commands
ditto. A while back, I hacked the grass shell (grass4.1 and GIS.sh)
so that using as something like:
grass4.1 [-ef] [-d database] [-l location] [-m mapset]
I don't recall exact usage. the -f flag means "fast" (don't go
through annoying init screens). the -e flag means "fast exit" (don't
go through the usual exit-dance). the other options override defaults
in .grassrc.
Perhaps this could be extended a bit, e.g.,:
grass4.1 -c 'g.list rast'
(-c like /bin/sh, would imply -fe above).
Someone well versed in Bourne shell could probably do this pretty quickly.
It would make a nice enhancment for future versions (hint hint).

When the job runs at 10:30, I get a mail message saying my "at" job
produced the following message "TERM: Undefined variable." GRASS is
running when I submit the "at" job, but the operating system doesn't
hmm... what command? I just tried a quick test and didn't have
any problem:

Your "at" job "/var/spool/cron/atjobs/781126260.a" produced the following output:
----------------------------------------------
raster files available in mapset PERMANENT:
aspect geology rushmore soils.ph transport.misc
bugsites landuse slope soils.range trn.sites
don't know that it would make a difference, but
did you exit grass before the command was executed.
