Ok, that sheds light into the kind of workflow this might be useful in, like calling stuff from a launcher instead of a terminal or something like that and having them go through nq automatically. Personally, I would just keep the shell open, but options are cool.

You can use e.g. the "screen" utility to detach from a shell and later re-attach. I use this often: start something at work, detach, then go home, re-attach.

You can have multiple sessions, give them names, etcetera.

nohup detatches the process from the shell
