Using shlex, I now have this:
#!\Python27\python
import os, subprocess
path = os.path.join("C:\\", "Program Files", "Apache Group", "Apache2",
"htdocs", "ccc", "run_alert.py")
#subprocess.call(['SchTasks', '/Create', '/SC', 'ONCE', '/TN', '"test"',
'/TR', path, '/ST', '23:50'])
subprocess.call(['SchTasks', '/Create', '/SC', 'ONCE', '/TN', '"test"',
'/TR', 'run_alert.py', '/ST', '23:50'])
Both of the above commands throw the same error:
ERROR: The filename, directory name or volume label syntax is incorrect.Pls advise.
