BASH Terminal Process

Run Then Disown A Terminal Process
In this example we will use Synaptic as our example programme.

Terminal:~$

sudo synaptic & Output [1] 4711

Thanks Urban Penguin

Disown An Already Running Terminal Process
In this example Synaptic will be the already running process.

Terminal:~$ Press CTRL+Z bg Output [1]+ sudo synaptic & disown

You should now be able to close the terminal without Synaptic closing.

Thanks Urban Penguin
