please help me understand os.system() result

[anandpillai]

On windows os.system() returns zero if successful always
and nonzero othewise.

The documentation of this function says,

<quote>
Note that POSIX does not specify the returne value of the C system()
function, so the return value of the python function is system
dependent.

Linux is a POSIX system so you need not be surprised
at these return values as long as they are not less than
zero.
