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

    The tool is “screen” but it isn’t going to a file per se, just a session name. Edit: I guess tmux does the same. What do you see as the difference? Are you trying to also suspend execution so you can reboot?

      the use-case is to simply re-attach to a long-running process, I’m not too concerned about a session persisting across reboots, though that would clearly be amazing

        Screen should work with no problem. You just start the screen session, detatch when you want, reattach later. No problem.
