Hello RudiC,

I'm finally getting around to testing the code snippets you've provided. Here is the code I've added to my script as per the suggestion. The code is allowing me to connect to the list of servers from the $SOURCE_FILE, but I'm not capturing the vars from the first line of the 'IFS=$'\t' read' line. There is also no progress on which Input ip I'm connecting too when I'm in this read loop so I can't see if it's working.

My script ended after running through about 50 servers with the following error - id: cannot find name for group ID 1000.

Here is how I added the code to my script. I don't think I've added it correctly. Any pointers on what I did wrong?

Code:
exec < $SOURCE_FILE || exit 1
read header # read (and ignore) the first line
while IFS=, read -r InputHost\
 InputIP\
 MaintenanceWindowTag\
 UserAgentTag\
 ResourceProvisioner\
 OSType\
 OSVersion\
 OSDetail\
 Location\
 PowerState\
 ; do

IFS=$'\t' read FLAVOUR HOSTNAME IPADDRESS ACTIVE_KERNEL INACTIVE_KERNEL UPTIME <<- EOFREAD
        $(sshpass -p 'xxxxxxx' ssh -qno StrictHostKeyChecking=no -o ConnectTimeout=1 user@$InputIP <<- EOFSSH | tr $'\n' $'\t'
        cat /etc/redhat-release 2>/dev/null || lsb_release -a 2>/dev/null | grep Description | cut -f2
        hostname
        hostname -I
        uname -r
        rpm -qa | grep '^kernel-[0-9]' |grep -vE `uname -r`
        uptime | cut -d "," -f1
EOFSSH
        )
EOFREAD

       if [ "$status" == "$UNREACHABLE" ]
        then
                echo "$InputHost,\
                $InputIP,\
                cannot connect,\

        then
