Process java still being killed

nohup

I need to run a java program on my university servers. I'm remotely logging in through their servers via ssh

So I used nohup like so:

nohup java -jar project.jar &

However when I logout and close the terminal then log back into the server my process is missing/got killed off.

nohup only make program immune to SIGHUP and SIGQUIT signal. Modern shell maybe send other signals when you logout from your session, so there is no guarantee that your program is not killed, even running under nohup.

The better solution is using tmux or screen, or if you use bash, you can try:

$ java -jar project.jar &
$ disown

Add term at386 to your .screenrc in order to override TERM. If this doesn't help, try dtach instead of Screen (which doesn't do any terminal emulation itself).

When I need to run a script that will run for a long time, and I'm on an ssh session, I want either:

The task should continue even when the network breaks or when I pack my laptop and go away.

a. The task can finish without interactive input from me.
```
 nohup do_my_stuff &
```
b. The task might need something from me on stdin.
```
 man tmux
 history -w
 tmux
 do_my_stuff
```
The background process is somehow enhancing my current session and should die together with the session. A rarity.
```
 enhance_my_session  >>/tmp/enhance.$$.log 2>&1 &
```
I want the thing to spit some logs randomly at my ssh session. Wait, what? No, I would never want that. Thank you disown.
Another thing that I never want: convert the process to a fully detached daemon, but avoid starting it automatically at the next boot. I would never want that because I cannot predict when the system will reboot and who will be rebooting it.
