Hey Methyl, thanks again for the reply.

In my original question I posted both Operating Systems that I have been testing on (i.e. SLES 11.1 (Bash v3.2.51) -and- AIX 6 (KSH))...
I guess I should have made it a little more noticeable, sorry about that...

Also, on the AIX one I have installed Bash version 3.2.16(1), which is what I've been using to write my scripts.

Thanks for your suggestion I'll give it a try and post back...
Also, before that, I wanted to mention that I'm ssh'ed into the SLES server and opened up my script using:
Code:
# gedit myScript &
# echo $!
30398
# ps -ef | grep [g]edit
root     30398 30317  0 09:42 pts/0    00:00:00 gedit checkNRPE

As you can see it actually worked this time!
This leads me to believe that possibly another "background process" (or something like that) is begin started when
I issue the command to start the Daemon...?

Does this sound like a possibility..?


Thanks Again,
Matt

Hello Again,

I just tried your command (with the 'nohup') and still getting the same results.

Here is the exact output when issuing those commands:
Code:
# nohup /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d &
[1] 2927
nohup: ignoring input and appending output to `nohup.out`
# echo $!
2927
[1]+  Done                    nohup /usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
# ps -ef | grep 2927
root      2937  2431  0 11:31 pts/4    00:00:00 grep 2927

So I'm guessing there is something weird going on within that command when I execute it...

I'm thinking of just starting the Daemon from within a Bash script, then within that script
just find the PID after it's started and write it to a file...


Thanks Again for Your Help,
Matt
