I think I did, a couple times, anyway, here's some more.
I have a new server, hosted at a remote location, a server farm in Brooklyn. I wanted to reconfigure some stuff with the network connection. Fine. How do you disconnect and reconnect, bring down and then bring back up, your network connections, from a remote host? If you bring them down, you won't be connected to bring them back up! Aha, you think, put it in a script. That's part of it, but not all. If the script is running and then you disconnect, the script will stop running unless you give it nohup.
