A simple unix/linux daemon in Python

http://www.jejik.com/articles/2007/02/a_simple_unix_linux_daemon_in_python/
by Sander Marechal

I've written a simple Python class for creating daemons on unix/linux systems. It was pieced together for various other examples, mostly corrections to various Python Cookbook articles and a couple of examples posted to the Python mailing lists. It has support for a pidfile to keep track of the process. I hope it's useful to someone.

Below is the Daemon class. To use it, simply subclass it and implement the run() method.

And here is an example implementation. It implements the daemon as well as it's controlling client. Simply invoke this script with start, stop or restart as it's first argument.

That's it! I hope this is of some use to someone. Happy coding!
