detach a process
 

how can I detach a process from a terminal and reatach it ?

If you're running a process and you want to background it, you can type control-z to pause it, then type 'bg' to background that process.

To bring that process back to the foreground, type 'fg'. If you have more than one process backgrounded, 'jobs' will list the backgrounded processed than then you can just use 'fg' with the right number. VIOLA

To start detached in the first place, put an '&' at the end of the command:
