start an program background

[aloneattack]

Hi,
I have a question, need your suggestions. We have programs those can be call to operate in background like this:

$] prog &

Then it can run in background mode of one shell. However, some programs will survival when we close the shell, but some programs won't.
I don't know why that is.
And then, would you tell me how to perform any program in background mode and that program still running even when the shell is closed ?

Thank you.

I think the easiest way is to use the 'screen' program... e.g. when you need to perform a remote access to another machine to run a long process... once logged in, you can start a screen, it will open a shell that can be used normally, so when you have the-long-process running, Ctrl + A, D detach the shell and you can do anything else (even logout from your remote session)... more info here GNU Screen: an introduction and beginner's tutorial || kuro5hin.org
