You can use screen sessions but typing the following command:

screen

Creating a screen session with session name:

screen -S <name>

screen -list

or

screen -ls

Example

# screen -list
There are screens on:
	6470.pts-1.hostname	(Detached)
	6839.pts-1.hostname	(Detached)
2 Sockets in /var/run/screen/S-root.

The following command can be used to detach from a screen session without closing it.
This will leave the current command running:

"Ctrl-A" and "d" to detach the screen

"Ctrl-D"

screen -r 6470.pts-1.hostname

"Ctrl-a"

Ctrl + a then hit Esc
