Hello everybody,
I'm new to python and I'm trying to build up a script...
When I run the script the only commands that are executed are
cmdargs1= ["elevation=%s" %dtm]
cmdargs2=["slope=slope1", "format=percent", "--overwrite"]
os.execvp("r.slope.aspect", ["r.slope.aspect"] + cmdargs1 + cmdargs2)
The other commands are ignored...What can be the issue?
thanks,
Monia

Here is my script:
