I am using ssh to connect to another (faster) computer in order to run some python code there. As I expect it to run several hours, I would like to disconnect after running it, like this: 

$ ssh user@my-other-computer
$ python file.py &
$ exit

However, if I try this, I get the message: 

zsh: you have running jobs.

I tried using nohup:

$ nohup nice python file.py &

but to no avail.

How can I achieve my goal?

I don't know why nohup does not work (maybe because of the nice, it could work without the nice command) but there are alternatives:

  • screen creates a new terminal that is not bound to your session (you can detach a screen session usind screen -d or Contr+A and then :detach and attach to it again using screen -r). You can run the comand using screen python file.py

  • tmux is a terminal multiplexer. It is like screen but has more features and it's faster. You can open a tmux session using tmux and run python file.py in the newly created session. You can detach using Contr+B and d or tmux detach-client.

  • disown is a shell command that disowns all jobs from the current shell that you can close it and the jobs will stay running.
