===Using screen for session management ===
Using screen manager, one can multiplex the same terminal to multiple. Multiple users can join the same screen session. Multiple screens can be created on the same screen session. Even if one "detach" from a screen, it will continue to work in background. Useful for running time-consuming tasks. Screen logging can be enabled as well.

On current window, type
%%(bash)
screen -D -R
# ^aDD to destroy sessions
%%

Then list the screen number
%%
[root@gigan root]# screen -ls
There are screens on:
31619.ttyp2.gigan (Detached)
4731.ttyp2.gigan (Detached)
2 Sockets in /tmp/screens/S-root.
%%

On subscribing terminal, type screen -xr <screen number>
%%(bash)
screen -xr 31619.ttyp2.gigan
# ^ad to quit session.
%%

To detach, type ^a^d
To end current session, type **exit**

==Screen sessions==
On source window, type ^ac to create new sessions. ^aa to switch between sessions.
