reptyr VS minecraft_startup_script

Maybe https://github.com/nelhage/reptyr

https://github.com/nelhage/reptyr I guess this is what your looking for (it reparents a process, while retaining stdin/out using the ptrace syscall and some linux hacks iiuc)

Start CPython and import the libraries. Then keep the process running as a fork server. Whenever a new instance it needed, we make a fork (os.fork), and apply a similar logic as reptyr. Some technical details are here.

Very much reminds me of reptyr

- reptyr: https://github.com/nelhage/reptyr

using mosh means i don't get SIGHUP, and if i use my local display, i can open another mosh, reptr my old session (it's still there!) and keep on hacking.

I know there is reptyr to reattaching running process to another tty. You can probably do the same from within the program. There is an abandoned rust rewrite you can probably ignore.

Alternatively, there's also reptyr, which allows you to reattach to a detached process - thereby giving you access to the standard input and standard output of a running Minecraft server instance.

That being said if you wanna go for it here’s a startup script I used: https://github.com/jsnod/minecraft_startup_script

For Minecraft, it's usually just a ".jar" to launch (but it need to stay "alive" in the "Terminal" so usually using screen which let you disconnect/reconnect the terminal without interrupting what's running) but if you want to manage it, you either can use a script (there's plenty of it, on example: https://github.com/jsnod/minecraft_startup_script) or there's web interface that let you do that, either on Linux or Windows (on Windows: Fork is a good one. If you want to check more, there's a list of Minecraft server's wrapper).
