A helper script for SSH'ing into EC2 instances by name

ec2ssh.sh

#!/bin/bash
# SSH into an EC2 instance by name
# Author: [email protected] (SoThree.com).

set -e
if [ $# -lt 1 ]
then
  echo "Usage: `basename $0` instance_name"
  exit 1
fi

# get instance id
instance_name=$1

# get the instance address so that we can SSH into it
echo "Obtaining the instance address..."
instance_address=`ec2-describe-instances  --filter "tag:Name=${instance_name}" | grep INSTANCE | awk '{print $4}'`
echo "Done. Instance address: ${instance_address}"

ssh ${instance_address}

Is this using an old version of the AWS console API? I working through a couple of small issues, one being that ec2-describe-instances is now aws ec2 describe-instances.
