Top Forums Shell Programming and Scripting [SOLVED] Using "$!" to get the PID of the Last Ran Background Process Post 302703751 by mrm5102 on Thursday 20th of September 2012 11:38:20 AM

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

Nagios::Plugin::Config(3pm)				User Contributed Perl Documentation			       Nagios::Plugin::Config(3pm)

NAME
Nagios::Plugin::Config - read nagios plugin .ini style config files SYNOPSIS
# Read given nagios plugin config file $Config = Nagios::Plugin::Config->read( '/etc/nagios/plugins.ini' ); # Search for and read default nagios plugin config file $Config = Nagios::Plugin::Config->read(); # Access sections and properties (returns scalars or arrayrefs) $rootproperty = $Config->{_}->{rootproperty}; $one = $Config->{section}->{one}; $Foo = $Config->{section}->{Foo}; DESCRIPTION
Nagios::Plugin::Config is a subclass of the excellent Config::Tiny, with the following changes: o Repeated keys are allowed within sections, returning lists instead of scalars o Write functionality has been removed i.e. access is read only o Nagios::Plugin::Config searches for a default nagios plugins file if no explicit filename is given to "read()". The current standard locations checked are: /etc/nagios/plugins.ini /usr/local/nagios/etc/plugins.ini /usr/local/etc/nagios /etc/opt/nagios/plugins.ini /etc/nagios-plugins.ini /usr/local/etc/nagios-plugins.ini /etc/opt/nagios-plugins.ini To use a custom location, set a "NAGIOS_CONFIG_PATH" environment variable to the set of directories that should be checked. The first "plugins.ini" or "nagios-plugins.ini" file found will be used. SEE ALSO
