linux - running process background

Question

I want to run a process in a remote linux server and keep that process alive after close the putty terminal,

what is the correct command?

Answer 1

don't use that nohup junk, i hate seeing that on servers; screen is a wasting pile of bits and rot -- use tmux.

if you want to background a process, double fork like every other daemon since the beginning of time:

# ((exec sleep 30)&)
# grep PPid /proc/`pgrep sleep`/status
PPid:   1
# jobs
# disown
bash: disown: current: no such job

enjoy.
