Use ansible to get the current AWS CLI versions across your systems, using the SG inventory groupings

#get the AWS cli version from the servers in Ansible in an SG
SG=securityGroupNameofSomeSort && ansible security_group_${SG} -m shell -a 'currentAwsCliVersion=$(aws --version 2>&1 | cut -c 9-) && INSTANCE_ID=$(wget -qO- http://instance-data/latest/meta-data/instance-id) && echo $currentAwsCliVersion $INSTANCE_ID' | grep -v SUCCESS >> /tmp/jonathan_current_ver_aws_cli.txt

#get just the first and last columns, to loop through.
cat /tmp/jonathan_current_ver_aws_cli.txt | awk '{print $1 " " $NF}' >> tmp.txt && mv tmp.txt /tmp/jonathan_current_ver_aws_cli.txt

#loop though things and get the <<CLI_VERSION>> <<AWS Instance ID>> <<AWS Name tag>>
IFS='
'
for i in $( cat /tmp/jonathan_current_ver_aws_cli.txt )
  do
    INSTANCE_ID=$(echo "$i" | awk '{print $2}')
    CLI_VER=$(echo $i | awk '{print $1}')
    TAG_NAME=$(aws ec2 describe-tags --filters "Name=resource-id,Values=$INSTANCE_ID" "Name=key,Values=Name" --region us-west-1 --output=text | cut -f5)
    echo "$CLI_VER $INSTANCE_ID $TAG_NAME"
    sleep 1
  done

Sometimes, simple forloops will still get the job done.
