How to keep remote script running when dropping ssh?

Question

I ssh from my MacBook to a remote Linux and started a lengthy script (import 2000000+ lines of csv text records into MySQL). Too bad I have to take away my MacBook one hour later.

How can I keep the script running when I unplug my MacBook?

Answer 1

Use nohup and run your process in the background. Run your process like this:

nohup command &

Edit:
To nohup running processes: press ctrl+z, enter "bg" and enter "disown"

Answer 2

nohup is fine, but spartian. screen is powerful. Let's do:

screen
command

type Control-A, then d. This will detach the screen session. You'll see the detached session with:

screen -ls

To reattach a session:

screen -r
