I'm not sure how i missed the filename ....

Anyhow ... since the echo is ran on both execution it looks like the first part of the cmd never gets to be successfull or that echo would never gets executed on the redhat 6.1 server.

Code:
#redhat 6.1
ssh -l user server1 awk "' \$7 == \"6.1\" { exit 0 } END { exit 1 }'" /etc/redhat-release || echo $?  
1
#redhat 5.5
ssh -l root server2 awk "' \$7 == \"6.1\" { exit 0 } END { exit 1 }'" /etc/redhat-release || echo $?  
1

I was only following your own code, since you're the one that actually has redhat servers to test with.

Could you post the contents of the relevant /etc/redhat-release's then?

The only pertinent information is the redhat version.

Thanks.

Code:
GOOD
# cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 6.1 (Santiago)
BAD
cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 5.5 (Tikanga)

in that case:

Code:
ssh username@server grep -q "'6\.1'" /etc/redhat-release || exit 1
