Per the docs (http://docs.python.org/2/library/subprocess.html#frequently-used-arguments ): "If passing a single string [as the `args` argument], either `shell` must be True (see below) or else the string must simply name the program to be executed **without specifying any arguments.**" (emphasis mine) > So I tried this: > pgm = "SchTasks" > args = ['/Create /SC ONCE /TN "test" /TR "run_alert.py" /ST 07:50'] > #args = ['/Create', '/SC ONCE', '/TN "test"', '/TR "run_alert.py"', '/ST > 07:50'] > cmd = [pgm] > cmd.extend(args) > subprocess.Popen(cmd, stdout=subprocess.PIPE).communicate()[0] > but got this error: > ERROR: Invalid argument/option - <<the above argument>> > > If I use the other args list I get this error: > ERROR: Invalid argument/option - '/SC ONCE' > so apparently it liked the first argument. > > Please advise. Your tokenization of your command is incorrect. Consult the Note box in the docs regarding `args` tokenization, and apply it to your command: http://docs.python.org/2/library/subprocess.html#subprocess.Popen The-docs-are-your-friend-ly Yours, Chris -- http://mail.python.org/mailman/listinfo/python-list
