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.
