Hi.
Quote:
When invoked with the -p or -g flags, nohup arranges for
processes already running as identified by a list of process
IDs or a list of process group IDs to become immune to hang-
ups.

-- excerpt from Solaris man nohup
a useful addition to command nohup for Solaris users, but as era says, not usable (so far) in Linux -- nor aix, nor hp-ux, nor freebsd, etc. ... cheers, drl

$ nohup -p <PID>

on AIX UNIX ksh it work use it:
press (ctrl+z ) to stop that job
then run (jobs) it who id of stoped job_id
the for running that job in foreground use(fg %<job_id>)
the for running that job in background use(bg %<job_id>)
and to start it in nohup use (nohup `bg %<job_id>`)

In the version of aix that I use, I find:
Code:
$ jobs
$ version =o
aix 5.1
$ jobs
$ sleep 100 &
[1]     30552
$ nohup -p $!
Sending nohup output to nohup.out.
nohup: -p: A file or directory in the path name does not exist.
$ echo $!
30552

What version of aix are you using? ... cheers, drl

I tried that with AIX 5.3 ML6. Here is a link verifying that:

nohup Command

Still, i have seen in the meantime, while sifting through older documentation, that "-p" is nonstandard. I have never needed it until recently, when i looked it up and found that option - so i took it for granted, unaware that it is not as common as i thought.

i face the same problem with the nohup commnad,anyway if you want the nohup to run
successfully dont use the ctrl + Z,just close the telnet window and go out the system
login to the system again and you can see that your program is working
nohup /usr/bin/ksh <xxx>.sh
i try it on tru UNIX V4.0F and it works
