Apologies for not responding sooner to your helpful reply.
Here are some details of the Red Hat server I'm using:
Code:
$ uname -sr
Linux 3.10.0-1062.el7.x86_64
Code:
$ bash --version
GNU bash, version 4.2.46(2)-release (x86_64-redhat-linux-gnu)
I'm trying my hand at this script again. I've used your suggestion:
Code:
#!/bin/bash
for server in server1 server2
do
ssh -x "$server" '
echo "hello I am on `hostname`"
sudo yum update infolist
' 2> >(sed "1i\\
$server:" >&3)
done 3>stderr
I can successfully login to a server and I receive the echo that says "hello I am on 'hostname'" so the script is working and gives me this detail back. But I don't receive any other data back after running this script against my test server? Would this be the result if rpmdb open failed wasn't occuring on this test server? What I mean is...will the above script only show if rpmdb open failed exists and if it doesn't the script returns nothing back?
Thank you.

RHN_CHECK(8) Red Hat Network RHN_CHECK(8)NAME
rhn_check - check for queued actions on RHN and execute them
SYNOPSIS
/usr/sbin/rhn_check [-v] [--verbose]
DESCRIPTION
rhn_check is a client program that connects to the Red Hat Network backend servers and retrieves information associated with the queued
actions for this particular system. This script reads the digital server ID from /etc/sysconfig/rhn/systemid and uses that to identify the
machine to the Red Hat Network. Upon successfull authentication, rhn_check will start processing the queued actions sequentially.
ACTION TYPES
The following types of actions are currently processed by rhn_check:
action type description
() ()
refresh This action will refresh the hardware or software profiles of this
machine with Red Hat Network. This fucntion is called as
refresh(hardware) or refresh(rpmlist)
new_systemid This action is used by the RHn Backend to update the Digital
system ID of this machine with a new one.
update_packages This action will trigger rhn_check into running a package
update for a list of packages queued from the Red Hat Network.
rhn_check will use modules from the up2date client to download
the packages, solve dependencies and install the on the system.
FILES
/etc/sysconfig/rhn/systemid The digital server ID for this machine if the system has been registered onto Red Hat Network. This file does
not exist otherwise.
