Managing awk return code over SSH command
Hello all,

This bellow code works. I'm just trying to find a simplified way to achieve this. I'm sure there is an easier way and it must be to simple for me to find.

Verify that the OS version is 6.1. If not exit the script. Of course if i just put a && exit 1 at the end of the ssh command it returns true so the script exits.

Thanks.

Code:
#!/bin/bash

OSVER=$(ssh -l root server1 "awk '\$7 != 6.1 {print \"NOTGOOD\"}' /etc/redhat-release")

if [ "$OSVER" == NOTGOOD ]; then
        echo "ERROR: This release is for RHEL 6.1"
        exit 1
fi

ssh-argv0

SSH-ARGV0(1)                                                BSD General Commands Manual                                               SSH-ARGV0(1)

NAME

     ssh-argv0 -- replaces the old ssh command-name as hostname handling

SYNOPSIS

     hostname | user@hostname [-l login_name] [command]

     hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name]
     [-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command]

DESCRIPTION

     ssh-argv0 replaces the old ssh command-name as hostname handling.  If you link to this script with a hostname then executing the link is
     equivalent to having executed ssh with that hostname as an argument.  All other arguments are passed to ssh and will be processed normally.

OPTIONS

     See ssh(1).

FILES

     See ssh(1).
