Well the point is not the difference between return values of os.system under Windows and Linux. The point is that I set the exist code of child process with os._exit() which works fine on Windows but on Linux the process.exitcode returns always 0. What is very strange is, that if I set return code to some other value, like: ... os._exit( len(cmd) ) ... Then I got exit codes 3 and 2 under Linux, which is correct. But when I do something like this: ... ret = os.system(cmd) print ret # this print real value, like 32512 os._exit(ret) # exitcode of this child process will be 0 on Linux ... It doesn't work, which seems very strange to me. -- http://mail.python.org/mailman/listinfo/python-list
