[GRASS-user] Adding options to grass.run_command

[Hanlie Pretorius]

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, ...)
