We can use Ctrl-z to stop the current job followed by
bg
to send it to the background, but can we do this in one action that doesn't briefly pause the execution of the program?
Is there a combined
Ctrl-z + bg
type command that we can use?
Short answer, no, but check https://superuser.com/questions/378018/how-can-i-do-ctrl-z-and-bg-in-one-keypress-to-make-process-continue-in-backgroun for a hacky solution to implement a faster backgrounding.
