[GRASS-user] Adding options to grass.run_command

Hi,

I'm writing my first GRASS Python script and am having trouble adding
options to commands that I want to run. For example, the following
works:
-----
grass.run_command("r.in.xyz", input=directory+'/'+file,
output=rainraster, fs=',', x=2, y=1)
-----

but this doesn't:
-----
grass.run_command("r.in.xyz", --overwrite, input=directory+'/'+file,
output=rainraster, fs=',', x=2, y=1)
-----

neither does this:
-----
grass.run_command("r.in.xyz --overwrite", input=directory+'/'+file,
output=rainraster, fs=',', x=2, y=1)
-----

How can I get this to work, or is there a better way of doing it using
a command other than grass.run_command?

Thanks
Hanlie

grass.run_command("r.in.xyz", input=directory+'/'+file,
output=rainraster, fs=',', x=2, y=1)

better `input = os.path.join(directory, file)`

but this doesn't:
-----
grass.run_command("r.in.xyz", --overwrite, input=directory+'/'+file,
output=rainraster, fs=',', x=2, y=1)
neither does this:
-----
grass.run_command("r.in.xyz --overwrite", input=directory+'/'+file,
output=rainraster, fs=',', x=2, y=1)

should be `overwrite = True` instead `--overwrite`

Likewise for "quiet" and "verbose".

Any normal (single-dash) flags must specified via "flags=...", e.g.:

  r.something -a -b -c ...

becomes:

  grass.run_command("r.something", flags="abc", ...)
