Hmm, I don't think this helps...

$ nohup sleep 30 >/dev/null 2>&1 &
[1] 17842
$ kill $! >/dev/null 2>&1
[1] + Terminated           nohup sleep 30 > /dev/null
2>&1

Follow the nohup by a "disown %1", which will
remove the task from  
interacting with your shell.  Of course, either your shell
needs to  
support the disown functionality, or the task you run needs
to have  
the capability.  Otherwise consider:

     /usr/sbin/daemon echo "yeah" 2>&1 >
/dev/null

You could also hunt down DJB's daemontools, which have
similar  
intentions...

Hi,

I'm just curious how it's possible that you have the
/usr/sbin/daemon on 
your NetBSD. I can't find it on NetBSD 2.0.2, 2.1, 3.0 and
current but 
yes, there is one on the FreeBSD 5.4 here ... 

Regards,

r.

  I
didn't claim NetBSD has daemon, but a motivated person could
 
build one for NetBSD from here:

   http://www.freebsd.org/cgi/cvsweb.cgi/src/usr.sbin/dae
mon/

...and it would likely solve the OP's problem.
