All nohup does is block a HUP signal from being sent to the process when the shell exits. Some scripts like /bin/sh don't do that. Rarely, some applications ignore HUP.

How you enable or disable job control is shell-dependent.

man sh

man bash

man nohup

man -s 3HEAD signal

I don't believe that nohup will disconnect STDIN from the shell in all cases. When you log out, if you take STDIN with you, some programs might complain. You should also redirect STDIN to /dev/null if it's not already redirected.-- Darren

If you are interested in knowing how the program is doing later on you could always download and use an utility called 'screen'. Screen will allow you to detach an and later reattach the shell running the command. .7/M.

Also have a look at screen, it should be in /opt/csw/bin/screen
