Incluso el viejo bash está usando & para enviar procesos a segundo plano, pero también hay algunas otras formas ... pero las dos básicas son estas:
1.)$~ your_command > outputfile_for_stdout &
# runs your command in background, giving you only PID so you can exit that process by `kill -9 PID_of_process`
# & goes at the end of row
2.)$~ your_command > outputfile_for_stdout
# this will run your program normally
# press Ctrl + Z then program will pause
$~ bg
# now your program is running in background
$~ fg
# now your program came back to foreground
3.)you can run terminal window under screen command so it will live until you either kill it or you reboot your machine
$~ screen
$~ run_all_your_commands
# Ctrl + A + D will then detach this screen
$~ screen -r will reattach it
Algunos otros comandos útiles:
$~ jobs
# will show you all processes running right now, but without PID
$~ ps
# will show you all processes for actual terminal window
