Lars:
We, too, have had this problem of GRASS leaving leftover temporary
files which take up lots of disk space and never go away.
I'd be willing to bet that you use GRASS the same way that we do -
from the UNIX prompt outside the GRASS shell. This is a convenient way for
us to use GRASS, and only requires that the requisite environment variables
be set properly.
One of the last things that the GRASS shell does is execute
$GISBASE/etc/clean_temp - which will remove all of those pesky temporary files
after checking that the processes associated with them are finished. If you
will just execute this program as the last act of your script files, I think
that your problems will disappear.
In fact, all you have to do is enter and exit the GRASS shell as the
owner of those files, and the shell will execute clean_temp for you and clean
up your disk.
I'm interested to know how many other users out there in netland are using
GRASS in this way?
