Recently I found tmux. This is a best thing if you manage to work with your server in ssh console on a bad connection or from time to time and would like to save the entire context of what you are doing. For example, you compile kernel and went take a coffee, then back and connection dropped. If you used tmux simply attach to session:

$ tmux a

Need (like me) several consoles? (It's for sure more verbose than to have nohup or Ctrl-z; bg)

<Ctrl-b> , enter "new" <Enter>

For a list of sessions:

<Ctrl-b> , s

(then select from stable list - meaning you remember that for example your unprivileged session is always third one, and first two is sudoed root ones). Example (selected 2nd):

(0) + 0: 1 windows
(1) + 2: 1 windows
(2) + 3: 1 windows (attached)

The only not a good (yet) thing is scroll up as it needs 2 more keys:

<Ctrl-b>, [, then <PgUp/Down> or Arrows

Have fun!
