How to use nohup to continue to run a command after the user logout?

Running:

nohup command ... > file &

will leave stderr and stdin open. Instead, run:

nohup command ... > file 2>&1 <&- &

or:

nohup command ... > logfile 2> errfile <&- &

which will redirect stdout and close stdin.

Keep in mind that your command may abort if it can't read from stdin.
