## Usage:  cfvalidate   file.template [ file ...]
##############################################################################
## Convenience wrapper script for aws cli 'cloudformation validate-template'
## which requires a inline, file URL or S3 url for  templates to validate
## This script takes simple, absolute or relative filenames and validate them
## using the AWS API 
## https://aws.amazon.com/cli/
##
## Requires that the AWS CLI is in your path and the default profile configured
## 
[ $# -gt 0 ] || { echo "Usage: $0 template-file [file ...]"; exit 1 ; }

for f ; do
echo $f
aws cloudformation validate-template --template-body file://$f || echo Failed $f
done

Added screenshots of Oxygen External Tool configuration dialog and how it looks when the tool is added.
Something this simple could be inserted inline into Oxygen without the script.
