I may be misunderstanding what you're trying to achieve, but you can simulate the bash '&' operator for a running process by pressing ctrl-Z to suspend the process and send it to the background, then running 'bg' to continue the process in the background.

Yeah I was unclear there - I meant the other use of the & operator, 'foo & bar' where bar starts after foo completes. AFAIK, if you ran foo by itself, there's no way to make bar automatically run after foo completes.

I had that need and made something a lot simpler: https://github.com/tv42/wait-for-pid

The few times I built TUIs with ncurses I wondered: why do I have to program so much by myself?
ncurses is so basic, I didn't have too much fun building UIs with it (more than once). Is there a wrapper or a more modern alternative out there that provides containers and widgets like most GUI frameworks do?
My side-project, in essence, the bash '&' operator for cases where the first process is already running. It took me months of searching before I could believe that this doesn't already exist, but there you go. I gave in to feature creep, of course, so it's a bit more than that now (I made a ncurses-based dashboard? Why??) but someday soon I'll make it public.
