Delegate a process to a file, for later reattachment? (feddit.uk)

Is such a think possible under Linux?

Yeah I know I can tmux / nohup, and I know that if I dig deep enough I can manually reattach some of the file descriptors under /proc to get a working terminal for that process again....

... but is there a tool that automatically does this somehow?

e.g.

run -d ./bash long-running.sh  >  proc.file
### later
run -a  proc.file

Edit: Y'all really know how to recreate the feeling of StackOverflow circa 2018

Not sure what you want. You're trying to monitor that process so you can tell when it finishes? You want to know when the file is closed? You can do that with inotify(2).
