I executed the command below in a linux shell:

$ nohup run &

Here run is a blocking command. Then I close the shell and start a new one. However in the new shell I cannot bring the task to foreground via fg, nor can I see it via jobs. Is there still a way to bring it to foreground?

CodePudding user response：

From what I understand, run is a subprocess of the shell, and when the shell closes, run also closes. Maybe using tmux or screen can achieve what you want.

CodePudding user response：

Use screen instead of nohup:

screen -dmS demo bash -c 'while ! read -t 1;do echo $((i  ));done'

Note: there are no &.

Then exit... Later, you could:

screen -x demo

Hit keys Ctrl a, then d to leave console running

Or

gnome-terminal -e 'screen -x demo'

Then, simply close window to leave process running.
