def main(self,argv):
do stuff.......
if __name__ == '__main__':
main(sys.argv[1:])
When my script is run, how can I cause it to immediately run main() as a background process? It will run to completion and outputs information to a file.
I forgot to say...the goal is to be able to run this on any OS. I do not want to modify the way the script is called in the command line, I want the script itself to cause it to run in the background.
easy:
$ python yourpythonscript.py &
The os will handle that for you ;) Of course, you will have to state if this is on windows or *nix.
If you are running this under windows, you might want to check the cmd.exe program - I think there is an option there for running its arguments as a background process...
Or if you are running this under linux machine, you can check the process by using ps aux | grep yourpythonscript.py
On Windows, run the program using pythonw.exe instead of python.exe.
On Unix and MacOS, use the Python daemon recipe or the python-daemon package.
I would use the Python threading library. This will allow you to run main() in the background.
In linux You could use & to run it on background and if you want it to be run even if you close that shell use nohup command:
nohup python yourpythonscript.py &
