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

    Oh a systemd-logger, I dont have access to the logs, only the admin does. Plus I can’t reattach to the process that way

      You can use it to log to a defined file in userspace. You don’t need to “reattach” to the process because all of the output goes through this util. Use signal handling to control the process.

        You’re probably right that that’s likely enough for non-interactive tools
