before running your app, execute screen. Run the app you want to run,
press Ctrl-A to get screen's attention, then D to detach, then logoff.
screen will continue yur app until done, return to the console and wait.
Next time you log in, type 'screen -r' to resume your screen session,
and then you're back where you started. The beauty is that you don't
need to login remotely to resume your screen'd session. You can resume
it from a local login, and vice versa.
For instance, I started an update to KDE 3.2.2 last night while logged
in at home in a screen session. When I got in to work, I ssh'd into my
home box, resumed the screen session, and found that the update worked
without error.
'man screen' for more details.
HTH,
Tim
