When use awk in script, may suffer shell unexpected expanding:
ssh -o StrictHostKeyChecking=no sshrm1 "ifconfig eth0 | grep \"inet\" | awk '{print $2}'"
Above will not get right data, instead preceding \ before $
ssh -o StrictHostKeyChecking=no sshrm1 "ifconfig eth0 | grep \"inet\" | awk '{print \$2}'"
Another method is awk the return value from ssh rather than wrap it in ssh command.
