You don't say what platform you're on, but from your description of
the problem, it's not Unix:
py> os.system("grep foo /dev/null")
256
py> os.system("grep foo /no_such_file")
grep: /no_such_file: No such file or directory
512
os.system is a simple wrapper around the C system() function. It's
return value is the same as that function. On unix, that's the 1/0 you
want in the upper byte, and status information in the lower byte - so
you divide by 256. I have no idea what Windows does in this case.
I'd recommend using the subprocess routines instead of os.system. They
are much more powerful/flexible than os.system.
