For an example, see
scripts/r.in.aster/r.in.aster.py
therein, this function is used:
grass.try_remove(tempfile)

Hello !
I would like to delete temporary files during the process
of a python script. I have look at g.tempfile but it seems I
don't know how to use it in a python script.
I have tried :
PROCESS_ID = os.getpid()
...
TEMP1 = grass.read_command ('g.tempfile',
pid = PROCESS_ID)
But this changes nothing, after about 67200 calculations of
r.viewshed no more temporary file can be created and the
script stopped.
Are you manually removing the TEMP1 files within your script? I
think that GRASS cleans up tempfiles only when the session exits,
so with such a large number of calculations, you should manually
remove them within the script.
It seems to me that i miss something... If anyone knows how
to solve that ?
Thanks for your help
