running a script like a daemon

[ivan le magnifique]

Hi there.
I would like to know how to launch a script from the command line (like via
telnet) with the ability to exit the command line without stopping the
thead.
Afterwards I would like to be able to retrieve the id of the thread to kill
it.
I know this is not really Python related since I have had the problem with
Java already ( before my conversion to Python)... but, any idea would be
appreciated.

Thanks

To write the daemon's pid to a suitable file (you wrote thread, but that
makes no sense -- I assume you mean process...?!), see os.getpid.

In most flavors of Unix, you can append the '&' character to the command,
which causes it to execute as a background process, and prepend 'nohup' to
it, which I think makes it continue even if you log off. I'm not a Unix
expert, so my explanation may be flawed, but this is what works for me:
nohup command &
